A guide to the stones we love

Agate is a banded form of chalcedony — a microcrystalline quartz that forms slowly inside pockets and gas bubbles in old volcanic rock, layer settling on layer over long stretches of time. That patient, ringed growth is exactly why it's found in such soft, earthy bands, and it's part of the stone's charm: every slice is a little cross-section of its own history. You'll find it the world over, from India to Botswana to the beaches of the UK, in colours from smoky grey to warm honey.

In folklore, agate has always been one of the great steadying stones — the kind kept in a pocket when life feels scattered and you'd like to feel more rooted in yourself. It's tied to the root chakra and a quiet sense of security. Many people simply hold a tumbled piece in the palm when their thoughts are racing, letting those slow layers be a reminder that steadiness, like the stone itself, builds up gently over time.

Also known as Amazon stone

Amazonite is a blue-green variety of microcline feldspar, and that dreamy colour comes from tiny traces of lead and water locked in its structure. It grows in coarse granite and pegmatite, often streaked with pale lines of albite that give it a soft, watery, almost tumbled-sea look. Despite the name it isn't actually found in the Amazon — it was named after the river long ago, and most of today's stone comes from Russia, Madagascar and the USA.

It's long been called the stone of truth and courage, kept close by people who want to speak their mind kindly and let a bit of old worry drift away. Sitting with the throat and heart chakras, it's said to soften both what you say and what you fret over. A common way to use it is to keep a piece where you have difficult conversations — by the phone, on the desk — as a small nudge towards honest, gentle words.

Also known as Baltic amber, succinite

Amber isn't a crystal at all, but the fossilised resin of ancient trees — sap that oozed out, trapped the odd insect or leaf, and then hardened and mineralised over millions of years. That organic origin is why it's so warm and light in the hand, sometimes still carrying a tiny prehistoric visitor inside. Most comes from the Baltic region, where it washes up along the shore, and from the Dominican Republic.

Because it holds a literal piece of sunlight and old life, amber has been treasured as a warming, protective talisman since the earliest times — one of humankind's very first gemstones. Linked with the sacral and solar plexus, it's associated with vitality and lifting a heavy mood. People often wear it against the skin, where its warmth is easy to feel; just keep it away from perfume and harsh cleaning, as it's soft and prefers gentle handling.

Amethyst is the purple variety of quartz, coloured by traces of iron and a little natural irradiation deep in the earth. It grows as glassy points lining the hollows of volcanic rock — the great geodes and 'cathedrals' from Brazil and Uruguay are amethyst-lined bubbles that took ages to fill. Zambian amethyst tends to a deeper, redder purple; Brazilian is often softer and more lilac.

It's the best-loved calming stone there is, long associated with peace, intuition and restful sleep — the Greeks even believed it guarded against overindulgence. Belonging to the third-eye and crown chakras, it's the stone of stillness. The simplest way to use it is to keep a piece by the bed for gentler nights, or hold it and breathe when a day has been a lot. One practical note: amethyst will slowly fade to pale if left in strong sunlight, so it's happiest somewhere shaded.

Also known as Vera Cruz amethyst

Vera Cruz amethyst is a distinct and much-loved find from Veracruz in Mexico: slender, prismatic, exceptionally clear crystals in the palest lilac, often doubly terminated and perched delicately on a pale matrix. It's far more fragile and far paler than the chunky purple geodes from Brazil and Uruguay, and collectors prize it for its clarity rather than its colour saturation.

It's considered one of the gentler amethysts — associated with quiet clarity and meditation rather than the deeper, more enveloping calm of dark amethyst. People often keep a small cluster where they sit to think. The crystals are slim and snap easily, so handle with real care, and keep it out of sunlight, which will bleach that delicate lilac away.

Also known as Bolivianite, trystine

Ametrine is a natural two-in-one: a single quartz crystal that grew with zones of both amethyst purple and citrine gold, the two colours meeting where differing temperatures set the iron within slightly differently. Almost all of it comes from one remarkable mine in Bolivia, which is part of what makes it feel a little special. Cut and polished, the boundary between violet and yellow can be beautifully sharp.

Naturally, folklore reads it as holding the calm of amethyst and the sunny warmth of citrine at once — a stone of balance. It bridges the crown and the solar plexus, and people reach for it when they'd like to feel both settled and quietly motivated: clear-headed, but with a bit of get-up-and-go. Like amethyst, its purple half can fade in strong sun, so keep it out of a hot windowsill.

Also known as Korite, Alberta ammolite

Ammolite is one of very few true gemstones of organic origin, formed from the iridescent aragonite shell of ammonites that lived in the inland sea covering Alberta some seventy million years ago. Only a small area produces gem material, and it's usually thin enough that it's sold as a doublet or triplet — backed and capped for strength. The colours can be as intense as fine opal.

In feng shui it's regarded as an exceptionally auspicious stone for prosperity and wellbeing, with each colour assigned its own influence. It's genuinely rare and worth treating as jewellery rather than a tumble. Keep it dry, shaded, and away from knocks and ultrasonic cleaners.

Also known as Ammonite fossil, Korite (when iridescent)

An ammonite is the coiled shell of a sea creature that swam the ancient oceans and vanished alongside the dinosaurs, and its spiral is one of nature's most perfect examples of the golden ratio — each chamber a little larger than the last, built as the animal grew. Most are now calcite or aragonite, the original shell slowly replaced; the rare iridescent Canadian material is sold as ammolite and is genuinely a gemstone in its own right. Whitby and the Dorset coast produce British ones, which makes them a lovely local find.

Because the spiral records steady growth over a lifetime, folklore ties them to cycles, evolution and taking the long view — a good stone for anyone in the middle of a slow change who needs reminding that progress is still progress. Hold one and you're holding a hundred million years, which does put a bad week in perspective. Being carbonate they're soft and dislike water, so keep them dry and dust gently.

Also known as Opal aura, rainbow aura quartz

Angel aura quartz is clear quartz that has been bonded with a fine vapour of precious metals (like platinum and silver), giving it a soft, iridescent rainbow shimmer. It's good to know it's a treated stone rather than a natural colour — the quartz is real, the shimmer is added — but the effect is genuinely lovely. The coating is delicate.

People give it a light, joyful folklore — tied to peace, gentle upliftment and a feeling of being softly supported, reaching for the crown. It's a pretty, high-hearted little companion for brighter days. Because the metallic coating can scratch or wear, handle it gently and keep water contact brief.

Also known as Blue anhydrite

Angelite is the pretty, powder-blue form of anhydrite — calcium sulphate that has lost its water. That's a detail worth knowing, because if angelite gets wet it will slowly reabsorb water and begin turning back into gypsum, softening and clouding; so it's very much a keep-dry stone. Most comes from Peru, in soft opaque pieces sometimes flecked with white.

With a name like that, it's little wonder it's tied to peace, comfort and the sense of being watched over. It sits with the throat and crown chakras and has a genuinely tender feeling in the hand. People often keep it somewhere they rest, or simply hold it in a difficult moment — it has the quality of a hand on the shoulder. Cleanse it with sound, sage or moonlight rather than water.

Also known as Obsidian nodules, Apache tear obsidian

Apache tears are small rounded nodules of obsidian that weather out of volcanic ash, tumbled smooth by nature and translucent when held to a light — unlike the fully opaque black obsidian they're related to. They come mainly from the American Southwest, and carry a sorrowful piece of folklore from that region about grief and remembrance, which is where the name comes from.

Because of that story they've become the gentle obsidian: kept for comfort through loss, for grief that needs holding rather than fixing, and for quiet protection while you're tender. People often keep one in a pocket through a hard season. Tough enough for everyday carrying, and fine with brief water contact.

Also known as Blue apatite

Apatite is a phosphate mineral — the same family that makes up the mineral portion of our own teeth and bones, which is a lovely bit of trivia to share. Its gem-quality blue and green forms are prized, though it's fairly soft at 5 on the Mohs scale, so it wants a little care. Fine material comes from Mexico, Brazil and Madagascar.

It has a reputation as a real get-up-and-go stone: motivation, fresh ideas, and finding your appetite for life again — fittingly, it's even linked with a healthy appetite in the everyday sense. Working with the throat chakra, it's associated with clear self-expression too. A common way to use it is to keep a piece on the desk when starting something new, as a small prompt to actually begin. Keep it out of prolonged sun, which can pale its colour.

Also known as Fluorapophyllite

Apophyllite forms delicate, glassy cubes and pyramids, often clustered on a bed of other zeolite minerals in the volcanic basalts of India. Its name comes from the Greek for 'to flake off', because it tends to peel and crumble a little when heated or dried out — a hint that it likes to be kept dry and handled gently. Freshly cleaved, it has a wonderful glassy shine.

It's thought of as a high, airy stone — one for calm, clarity and a peaceful feeling in a room, sitting with the third eye and crown. People often set a cluster where daylight can catch it and simply enjoy the fresh, uplifted atmosphere it seems to bring. It's popular in meditation corners for that reason.

Also known as Aqua aura, bonded quartz

Aqua aura is clear quartz that's been bonded with a fine vapour of gold in a vacuum chamber, which fuses to the surface and produces that unmistakable electric blue with an oil-on-water sheen. It's worth being straight about: the quartz is entirely natural, the colour is not. It's a modern treatment, not something the earth made, and there's no shame in that as long as it's sold honestly.

People give it a throat-chakra folklore — calm, clear expression and the courage to say the thing you've been sitting on — partly from the colour and partly from the gold. It's a striking piece for a shelf, and much loved simply because it's beautiful. The metallic bonding is thin and can scratch or wear, so handle it gently and keep water contact brief.

Also known as Blue beryl

Aquamarine is the sea-blue member of the beryl family (emerald is its green cousin), coloured by traces of iron and hardened to a durable 7.5–8 on the Mohs scale. It grows as long six-sided crystals in granite pegmatites, with much of the finest coming from Brazil, Pakistan and Nigeria. The name simply means 'water of the sea', which suits it perfectly.

Sailors once carried it as a talisman for safe passage, and it's still thought of as the traveller's stone and a stone of gentle courage — calming frayed nerves and helping honest words come from the heart. It belongs to the throat chakra and to the feeling of flow. A nice way to use it is to slip a piece in your bag before a journey or a hard conversation, bringing a little of that cool, unhurried sea-calm along with you.

Also known as Aragonite star cluster, sputnik

Aragonite is calcium carbonate — the same chemistry as calcite, but crystallising in a different structure, which is a classic textbook example of polymorphism. The familiar rusty-orange 'star clusters' or 'sputniks' from Morocco are interlocking blades radiating in all directions. It's also the mineral that molluscs use to build the nacre in shells and pearls, which is a lovely link to make.

It's kept as a grounding, patience-building stone — steadying, unhurried, good for anyone who rushes and then wonders why nothing sticks, working at the root and sacral. Being a soft carbonate it dissolves in acid and dislikes water, so keep it dry and handle the spikes with care, as they snap easily.

Also known as Star leaf stone

Astrophyllite forms golden-bronze blades that radiate outward like a starburst through dark matrix — its name means 'star leaf', which is about as apt as mineral names get. It comes from the same unusual alkaline rocks as eudialyte, mostly on the Kola Peninsula and in Norway. The blades are soft and micaceous, so polished pieces are cut to show the spray flat.

Its folklore is introspective: self-knowledge, recognising your own worth, and the slightly grand idea of seeing the light you carry. Whatever you make of that, it's a beautiful and unusual thing to own. Soft, bladed and water-shy, so it's best kept as a display piece and dusted rather than washed.

Also known as Blue quartzite aventurine

Blue aventurine is quartzite shot through with fine blue dumortierite fibres, which give it both its colour and the faint internal shimmer that defines any aventurine. It's a good deal less common than the green variety, and its restrained slate-blue makes it a favourite for palm stones and worry stones.

Where green aventurine is about luck and optimism, the blue is credited with calm clarity and self-discipline — thinking before speaking, and holding a line without heat, working at the throat and third eye. It's often chosen by people who want to be less reactive. Tough, durable and fine with brief water contact.

Green aventurine is a quartz shot through with countless tiny flecks of fuchsite mica, which give it a soft shimmer known as aventurescence — the very effect that lends the stone its name. It's an opaque, comfortably tough stone, most of it coming from India and Brazil, and it takes a lovely tumble-polish.

Long regarded as a bit of a lucky charm, it's associated with opportunity, gentle optimism and an easy, open-hearted confidence — the sort of stone people carry when hoping for a lucky break or simply wanting to feel more relaxed about taking a chance. It's a heart-chakra stone, warm and hopeful rather than showy. Keep it out of strong, prolonged sun, which can soften its green.

Red aventurine is quartzite glittering with tiny flakes of hematite or goethite, which lend it a warm brick-to-orange colour and a subtle sparkle. Paler, softer-toned material is usually sold as peach aventurine, and the two are essentially the same stone at different iron concentrations.

It's kept for motivation and physical vitality — a get-on-with-it stone rather than a contemplative one, sitting at the root and sacral. People reach for it during a slump or when a task has been put off one too many times. It's tough, everyday-durable and fine with brief water contact.

Also known as Chessylite

Azurite is a copper carbonate, and its astonishing deep-blue colour comes straight from that copper content — the same source that turns old bronze green. It's soft and a little fragile, and over long periods it can even alter naturally into green malachite, so pieces are sometimes found as a blue-and-green blend. Fine material comes from Morocco, the USA and Namibia.

Its intense blue has always tied it to insight and the thinking mind — a stone for those quiet moments when you're trying to see something clearly, sitting with the third eye. People tend to keep it near while pondering a decision. Because it's copper-based and soft, keep it dry and out of strong sun, and give hands a wash after long handling.

Also known as Grey moonstone, new moon stone

Black moonstone is a smoky grey-to-charcoal feldspar from Madagascar with a soft blue or silver sheen — technically closer to labradorite than to true moonstone, which is a recurring theme in this corner of the mineral world. Its darker body makes the flash look moonlit rather than bright.

It's become associated with new beginnings in their earliest, most private stage — the new moon rather than the full — along with intuition and a quiet, protective steadiness. People often use it when something is just an idea and not yet ready to be talked about. Handle it gently, as feldspar cleaves, and keep water contact brief.

Obsidian is volcanic glass — lava that cooled so fast it never had time to form crystals, leaving a smooth, glossy, jet-black material that our ancestors knapped into some of the sharpest blades ever made. That fiery, instant origin gives it a raw, honest quality. It's found wherever there's been the right kind of volcanism, from Mexico to Iceland.

It's one of the great protective, grounding stones, thought to gently draw off what you no longer need and help you feel solid and safe — rooted firmly at the base chakra. Many keep a piece by the door or hold it when they feel wobbly, letting its weight and darkness bring them back down to earth. It's often described as a mirror for looking honestly at oneself.

Also known as Schorl

Black tourmaline (schorl) is an iron-rich borosilicate that grows in long, ridged, striated columns — run a fingernail along one and you can feel the grooves. Remarkably, it becomes electrically charged when warmed or rubbed, which is part of why it's picked up such a protective reputation. Much of it comes from Brazil, Pakistan and across Africa.

It's the classic shield stone — kept by the front door or on the desk, long associated with protecting your space and quietly soaking up the day's stress, anchored at the root chakra. Think of it as a gentle bouncer for your good mood. A popular way to use it is to place a piece near where the world comes in — the doorway, the router, the workspace — and to cleanse it often, as it's said to work hard.

Also known as Heliotrope

Bloodstone is a dark-green chalcedony (a jasper, really) speckled with vivid red spots of iron oxide — the drops that give it its dramatic name. It's a tough, opaque stone, mostly from India, Brazil and Australia, and it takes a good polish. In the Middle Ages it was carried by warriors and believed to staunch wounds.

That old association with lifeblood carries through: it's an earthy stone of vitality and courage, kept close for strength when you're worn thin and simply need to keep going, working with both the root and the heart. It's a good one to hold when your energy is flagging — very much a get-through-the-week sort of companion. Everyday water contact is fine thanks to its hardness.

Also known as Fancy jasper bloodstone, plasma

Fancy bloodstone is a more mottled, multicoloured relative of classic bloodstone — green chalcedony with red iron oxide spots, plus yellows, creams and greys that make each piece more of a patchwork. Material without the red spots at all is properly called plasma. It's tough, common and inexpensive, which makes it a good everyday carrying stone.

It carries bloodstone's long reputation for vitality, courage and endurance — the stone for getting through rather than sprinting — grounded at the root with a heart note. It's a sensible choice for anyone facing a long slog. Hard-wearing and fine with brief water contact.

Also known as Blue lace agate's cousin, Mohave blue chalcedony

Blue chalcedony is the plain, unbanded form of the same microcrystalline quartz that gives us agate and carnelian — a soft, even powder-blue with a waxy, almost glowing translucence. Turkish material is particularly prized for its even colour. Where blue lace agate has stripes, this is a calm wash of colour throughout.

It's kept for kind, calm speech and for easing tension, sitting with the throat chakra — a soothing rather than stimulating stone, often chosen by people who find themselves snapping when tired. It's tough, takes a lovely polish and handles brief water contact without any trouble.

Also known as Blue sandstone, star stone

Blue goldstone is the cobalt-tinted sibling of brown goldstone, and again — it's glass, made rather than mined, with copper crystals suspended through it. Held under a light it looks uncannily like a night sky full of stars, which is why it's so often sold as 'star stone' and used for celestial-themed pieces.

Its associations are with ambition and calm focus — aiming for something distant without panicking about the distance. Honestly sold, it's a beautiful and inexpensive thing. Durable, stable, and needs no special care beyond avoiding knocks that could chip the glass.

Also known as Derbyshire spar, Blue John fluorite

Blue John is a banded purple-and-cream fluorite found in just two caverns in Castleton, Derbyshire — nowhere else on earth — and it has been mined there since at least Roman times. The bands come from hydrocarbons trapped in the crystal, and because the veins are nearly exhausted, only a few tonnes are now taken each year for craftsmen. Georgian Britain went mad for it, and grand houses still display Blue John urns and columns.

For a British collector it's a genuinely special stone: fluorite's calm, ordered clarity with a sense of place attached to it. It's kept for calm and gentle protection, and honestly quite often just for the pride of owning something so local and so scarce. It's soft and porous, so keep it dry and out of strong sun, and treat a piece as the heirloom it rather is.

Also known as Blue chalcedony lace

Blue lace agate is a pale, banded chalcedony threaded with delicate white and blue lacing — those wavy lines are growth bands, laid down as silica-rich water seeped through the rock over ages. Most of the best comes from Namibia and South Africa, and it's soft on the eye in a way few blue stones manage.

It's one of the most soothing stones there is, long tied to gentle communication, calm and the easing of an anxious, chattering mind — very much a throat-chakra stone. People keep it close before they have to speak up, or simply hold it when their inner voice has been unkind, and it seems to take the edge off. Being a quartz, it's fine with brief water contact.

Also known as Peruvian blue opal, Andean opal

Peruvian blue opal is a soft, milky sea-blue opal found in the Andes, coloured by traces of copper. It doesn't show the rainbow play of precious opal — its beauty is in the gentle, watery translucence, which cutters bring out with smooth domed cabochons. Fine, evenly coloured material is genuinely scarce.

It's kept for calm, clear communication and general soothing, sitting with the throat and heart — the sort of stone people reach for when they're frazzled. Its colour alone does half the work. Protect it from heat and prolonged sun, and never soak it, or it may craze.

Also known as Hawk's eye, falcon's eye

Blue tiger's eye — hawk's eye — is the earlier stage of the same stone as golden tiger's eye. The fibrous blue mineral crocidolite is gradually replaced by quartz; caught partway, it stays blue-grey, and oxidised further it turns the familiar gold. The same silky band of light slides across it as you tilt it, in a cooler, more restrained key.

Where golden tiger's eye is about courage and drive, the blue is kept for calm insight and perspective — taking the high, wide view of a problem rather than charging at it, which is where the hawk imagery comes from. It's a good one for stress and overthinking. Being quartz, it's durable and takes brief water contact happily.

Also known as Sunset agate

Botswana agate comes almost entirely from a single region of Botswana, banded in gentle greys, pinks and creams that make it instantly recognisable. Like all agates it formed layer by layer inside volcanic cavities, and it's tough enough for everyday handling. Its fine, even banding is prized by cutters.

It's traditionally the comforting stone for times of change and grief — steady, warm company while you find your feet again, working quietly with both the root and the crown. Some people call it the 'change stone' and keep a piece with them through a tender chapter, or give one to a friend going through something hard. A calm, undramatic sort of support.

Bronzite is a member of the pyroxene family with a warm brown body and a soft, metallic bronze shimmer created by tiny internal inclusions catching the light. It forms in igneous and metamorphic rock and is usually cut into tumbles and palm stones; much comes from Brazil and the USA. Being iron-bearing, it prefers to be kept dry.

It's associated with grounded confidence and a certain calm assertiveness — useful when you'd like to stand your ground kindly rather than sharply, sitting at the root chakra. Folklore even frames it as helpful for keeping your composure when others are being difficult. A good one to carry on days you need to hold a boundary without losing your warmth.

Also known as Bumblebee stone, eclipse stone

Bumblebee jasper comes from volcanic vents in Indonesia and gets its extraordinary yellow-and-black banding from sulphur and arsenic-bearing minerals deposited in soft sediment. And that's the important bit: it isn't a jasper (there's little quartz in it), and it contains arsenic compounds, so it should be bought as a sealed polished piece, kept dry, and handled with clean hands — wash them afterwards, and never leave it in drinking water. Reputable sellers seal it for exactly this reason.

Its folklore is all about boldness — seizing the moment, backing yourself, saying yes to the opportunity — which suits a stone born of volcanoes and coloured like a warning sign. It's a favourite for anyone in a timid patch. Just treat it as a display piece rather than a pocket stone, and keep it away from children and pets.

Blue calcite is a gentle sky-blue calcium carbonate with a very restful quality. As with its siblings it's soft (Mohs 3) and dislikes water, so it wants dry, careful handling; most comes from Mexico. Held to the light it has a lovely translucent glow.

It's long associated with calm, soft communication and peaceful recovery, sitting with the throat and third eye — a good stone for a bedside or a windowsill where you'd like an unhurried, gentle feeling. People often reach for it during times of rest and recuperation. Keep it out of water and strong sun.

Green calcite is a soft, minty-green calcium carbonate, cool and refreshing just to look at. Like all calcite it's gentle (Mohs 3), water-reactive and best kept dry; good material comes from Mexico and Brazil, often as smooth polished pieces that feel lovely in the hand.

It's thought of as soothing and renewing — a stone for letting go of tired old habits and welcoming a bit of ease, working with the heart chakra. Many keep one nearby when they're ready to turn over a new leaf, or to bring a calmer feeling to a busy room. Cleanse with sound or smoke, not water.

Orange calcite is calcium carbonate tinted a glowing, juicy orange by traces of iron and manganese. It's a soft stone (just 3 on the Mohs scale) and it reacts to acids and water, so it's a keep-dry, handle-gently sort of piece. Much of the brightest material comes from Mexico.

That warm colour gives it a naturally cheering feel, and folklore links it with creativity, playfulness and lifting the spirits on a flat day — a sacral-chakra stone of joy. People often pop it somewhere they'll see it when they feel stuck, letting its brightness get the ideas flowing again. Cleanse it with sound or sage rather than water, and keep it out of strong sun, which can pale it.

Carnelian is a warm orange-to-red chalcedony, its fiery colour coming from iron oxide within the quartz. It's a tough, glassy stone that the ancient Egyptians and Romans loved for seals and amulets, and it takes a beautiful polish; much comes from India, Brazil and Uruguay.

It's all about warmth and confidence — a lively stone kept close for courage, creativity and a bit of everyday spark, belonging to the sacral chakra. Carry it when you want to feel bolder, or set it where you make things, and it seems to lend a little momentum. Being a quartz it handles brief water contact well, though strong sun can very slightly soften its colour over time.

Cavansite forms little spheres and rosettes of the most extraordinary peacock blue, usually perched on a pale zeolite matrix, and almost all of it comes from a couple of quarries near Pune in India. The colour comes from vanadium, and the crystals are so delicate that good specimens are genuinely scarce and priced as collectors' pieces. Nothing else in the mineral world looks quite like it.

It's associated with insight and clear, calm communication — a third-eye and throat stone, favoured by people who want to think and speak with more precision. Mostly, though, it's admired: it's simply one of the loveliest blues in mineralogy. Fragile, water-shy and best kept out of strong light, so it belongs in a cabinet rather than a pocket.

Celestite (or celestine) forms clusters of pale sky-blue crystals — strontium sulphate, and in fact a key source of the strontium that colours fireworks and old TV screens red. It's soft and fragile at 3–3.5, and importantly it fades in sunlight, so it's a keep-shaded, keep-dry stone. The finest sky-blue geodes come from Madagascar.

It has a genuinely peaceful, uplifting presence, tied to calm, serenity and quiet reassurance, reaching for the crown and throat. People keep a cluster where they rest and let it bring a soft, hopeful hush to the space — it's a favourite for meditation corners. Just protect it from sun and water, both of which it dislikes.

Also known as Blue chalcedony, Mohave blue

Chalcedony is the umbrella name for the whole family of microcrystalline quartz — agate, carnelian, onyx and jasper are all chalcedonies — but on its own it usually means the soft, milky blue-white form. It grows from silica-rich waters seeping through rock, and it's tough and even-textured, taking a smooth, waxy polish. It's found worldwide.

This gentle form is regarded as nurturing and harmonising — long associated with kindness, easing tension and bringing people gently together, soothing the throat chakra. It's a lovely stone for a home where you'd like a little more calm and goodwill in the air. Being quartz, brief water contact is fine.

Also known as Peacock ore, bornite (often sold as such)

Chalcopyrite is a copper-iron sulphide whose surface tarnishes into extraordinary iridescent blues, purples and golds — the reason it's sold everywhere as 'peacock ore'. It's worth knowing that much material labelled peacock ore is chalcopyrite that has been acid-treated to force those colours, and that true bornite is a different (though related) mineral often sold under the same name. Naturally tarnished pieces tend to be subtler.

Its folklore is cheerful and uncomplicated: joy, creativity and a lift in mood, which suits something that looks like an oil slick made of treasure. It's a popular first mineral for children for exactly that reason. Being a sulphide it should be kept dry and handled with clean hands, and it's happiest as a display piece.

Charoite is a rare purple silicate found in just one place on earth — the Chara River region of Siberia — which is exactly where it gets its name. Its unmistakable swirling, feathery pattern of lilac and violet forms only under very particular geological conditions, so no two polished pieces look alike. It's moderately soft and best not soaked.

Folklore casts it as a stone of transformation and courage — comforting company through the deeper, more reflective patches of life, working with the crown and third eye. People tend to reach for it when moving through something big, finding it has a steadying, brave-heart feeling. Keep it out of strong sun, which can dull its colour.

Also known as Banded amethyst, dogtooth amethyst

Chevron amethyst is amethyst and white quartz that crystallised in alternating layers, producing sharp V-shaped bands — the chevrons that give it its name. The pattern records repeated pulses of mineral-rich fluid, each laying down its own stripe, so a polished piece is effectively a striped diagram of its own formation. It's tougher-looking and more graphic than plain amethyst, and takes a superb polish.

It's credited with amethyst's calm plus a sharper, more focused edge — the white quartz bands are often described as cleansing and clarifying, so the combination gets kept for clearing a cluttered head rather than simply soothing it. A good one for the desk when you need to think clearly under pressure. Like all amethyst, keep it out of strong sunlight or the purple will pale.

Chevron aventurine is green aventurine with distinct paler banding running through it, giving a striped or V-patterned appearance rather than the usual even green. The shimmer still comes from countless flecks of fuchsite mica caught in the quartz. It's a less common cut of a very familiar stone.

It's kept for the same reasons as ordinary green aventurine — luck, opportunity, an easy optimism — with the banding often read as adding structure or steadiness to that good fortune. A nice one for someone taking a considered risk rather than a wild one. Durable, and fine with brief water contact.

Chrome diopside is a vivid green pyroxene coloured by chromium, mined mostly in a bitterly cold region of Siberia where the season is short — which keeps supply limited. Its green rivals emerald in small sizes, hence the marketing name 'Siberian emerald', though it's softer and a completely different mineral. Larger stones tend to look almost black, so it's most beautiful cut small.

It's kept as a heart stone — forgiveness, renewal, and letting warmth back in after a cold patch. Its intense green suits growth and second chances. Being softer than most gems it wants gentle handling, brief water contact, and storage away from harder stones.

Chrysanthemum stone is a dark limestone or dolomite matrix in which pale minerals (often celestite or feldspar) have grown outward in radiating sprays that look uncannily like white flowers blooming in the rock.

Those stone 'flowers' give it a gentle, encouraging folklore — linked with the sense that good things are quietly unfolding in their own time, grounding and hopeful at once. It's a sweet reminder to be patient with yourself and let growth come at its own pace. A lovely piece to keep on a desk or shelf as a little visual metaphor.

Also known as Cymophane, cat's eye

Chrysoberyl is one of the hardest gems after diamond, sapphire and ruby, and its cat's-eye variety is the classic example of chatoyancy: a single bright line of light that glides across the dome as you tilt it, caused by parallel needle-like inclusions. When people say 'cat's eye' without qualification, this is properly what they mean, though the term gets borrowed for quartz and other stones too.

It has been carried for protection and good fortune across many cultures, with the eye itself read as watchfulness — a stone that keeps a lookout for you. It's also linked with seeing a situation clearly, which suits its remarkable optics. At 8.5 on the Mohs scale it's tremendously durable, so it wears well and takes water without any fuss.

Traditionally it's the stone of gentle expression and calm — kept close for soothing the heart and speaking softly and truly, sitting with the throat and heart. People keep it near when they need to say something tender, finding it helps the words come out kindly. As it's soft and copper-based, keep it dry and out of strong sun.

It carries a very hopeful feeling, long associated with joy, tenderness and an open heart — a heart-chakra stone through and through. People reach for it when they'd like to feel more forgiving, of others and of themselves, and to let a bit of lightness back in. Being quartz it tolerates brief water contact, though prolonged sun can pale its lovely green.

Also known as Serpentine cat's eye

Chrysotile is the fibrous form of serpentine, and honesty matters here: it is a form of asbestos. Solid, polished, sealed cabochons are considered safe to handle because the fibres are locked in place, but raw, crumbling or dusty material should not be cut, sanded or breathed anywhere near — that's a genuine health matter, not caution for caution's sake. Buy it polished and sealed, keep it intact, and don't work it yourself.

Handled properly, its silky golden-green chatoyancy is beautiful, and it carries serpentine's folklore of renewal and calm strength. Keep it dry, keep it whole, and if a piece starts to fray or shed, retire it rather than handle it.

Citrine is the sunny yellow-to-golden variety of quartz, coloured by traces of iron. Truly natural citrine is fairly rare and tends to a pale, smoky-lemon shade; much of the deep-orange 'citrine' on the market is heat-treated amethyst, which is perfectly lovely but worth knowing about. Natural material comes from Brazil, Bolivia and Madagascar.

It's one of the cheeriest stones going — famously the stone of abundance and optimism, kept close for confidence, warmth and inviting a little good fortune, belonging to the solar plexus (your seat of personal power). Many keep a piece where they work or keep their money. Natural citrine can slowly fade in strong sun, so a shaded spot suits it.

Also known as Rock crystal, master healer

Clear quartz is pure silicon dioxide, the most abundant and versatile crystal on earth — so useful that a sliver of it keeps time in watches and steadies signals in radios. It grows as glassy, six-sided points in an astonishing range of settings worldwide, from Brazil to Arkansas to Madagascar. Colourless and transparent, it's the blank canvas of the crystal world.

Known as the master healer and amplifier, it's thought to lift and clarify whatever you bring to it, and it works with every chakra — part of why beginners are so often pointed towards it first. A popular way to use it is to pair it with another stone to gently boost that one's qualities, or to hold it while setting a simple intention. One tiny caution: a clear point can focus sunlight like a lens, so don't leave one on paper in a bright window.

Also known as Salrose, cobaltoan calcite, pink dolomite

Cobalto calcite is calcite coloured an astonishing raspberry pink by traces of cobalt, usually forming a sparkling druzy crust over grey matrix. The best material comes from the Congo and is genuinely eye-catching — few natural pinks are this saturated. It's soft, delicate and priced as a specimen rather than a working stone.

Its folklore is unabashedly heart-centred: self-love, emotional healing and simple joy, and it's a popular gift for someone recovering from a difficult time. It's hard to be gloomy looking at it. Keep it dry, shaded and safe from knocks — the druzy crystals rub away easily.

Also known as Native copper

Copper is a native metal — one of the very first that humans learned to work — with a warm reddish glow and superb conductivity, which is exactly the quality that follows it into folklore. It's found in nugget and branching forms around the world, and it naturally tarnishes over time, so it likes to be kept dry and given the occasional gentle polish.

Because it conducts so beautifully, it's long been thought of as a stone that carries and enhances energy, associated with vitality and often paired with other crystals to help them 'sing' a touch brighter. Some people simply enjoy keeping a little copper alongside their favourite stones. Keep it out of water to slow the tarnish.

Also known as Lizard serpentine

The Lizard Peninsula in Cornwall is one of the few places in Britain where rocks from the Earth's mantle have been thrust up to the surface, and serpentine is the result — a soft, richly mottled green-and-red stone that Cornish craftsmen have turned on lathes for generations. Victorian holidaymakers took home serpentine lighthouses and vases by the crateload, and the workshops are still going.

It carries serpentine's general folklore of renewal and calm, with an added sense of connection to the land it comes from. It's a lovely stone for anyone with Cornish roots or a fondness for that coast. Soft enough to scratch with a knife, so keep water contact brief and store it carefully.

Also known as Covelline, peacock copper

Covellite is a copper sulphide with a deep indigo colour and a metallic iridescence that flashes bronze, pink and violet as it turns. It's remarkably soft — you can mark it with a fingernail — and forms thin platy crystals, which makes intact specimens uncommon. Fine material has come from Sardinia and Butte, Montana.

Its folklore concerns intuition and dreams, a reflective third-eye stone often described as helping you see what you're avoiding. People keep it near where they sleep or write. Being both soft and a sulphide, it needs a dry, protected home and clean hands.

Also known as Mexican lace agate, laughter stone

Crazy lace agate is a Mexican chalcedony whose bands, instead of running in orderly stripes, twist and fold into wild loops and swirls — the result of the host rock being deformed while the agate was forming. No two slabs look remotely alike, and cutters prize the most chaotic pieces.

Unsurprisingly for something so lively, it's known as the laughter stone: joy, good spirits and lightening a heavy mood, sitting with the solar plexus. It's often given to someone who's been taking things too seriously. Tough, cheerful and fine with brief water contact.

It has a naturally playful, grounding folklore — kept close to lift low moods, encourage a bit of fun and steady you at the same time, working with the base and sacral chakras. It's a good one for anyone who takes life a touch too seriously, and it's often given to children and the young at heart. Brief water contact is fine.

It's a very gentle, high-hearted stone, tied to peace, patience and setting down what's weighing on you, reaching for the crown and heart. It's a favourite for meditation and for quiet, restful moments — people often simply hold a piece and let their shoulders drop. An easy stone to care for, and lovely in the light.

Also known as Tree agate's cousin, dendritic chalcedony

Dendritic agate is translucent chalcedony containing black or brown branching inclusions that look convincingly like ferns, trees or frost on a window. They're not fossil plants, despite appearances — they're crystals of manganese and iron oxide that grew in branching patterns along fine cracks, a process called dendritic growth that follows the same mathematics as lightning and river deltas.

It's kept for growth and abundance, and for a deep sense of connection to the natural world — often called the stone of plenitude in older texts. Gardeners and plant-lovers gravitate to it. Durable and easy to care for, with brief water contact fine.

Also known as Gypsum rose, sand rose, selenite rose

Desert rose is a naturally sculpted rosette of gypsum (or sometimes barite) that forms in arid, sandy ground as mineral-rich water evaporates, trapping grains of sand between its blades — which is why each 'petal' has that soft, sandy tan colour. They're found in deserts from Mexico to Morocco. Being gypsum, they are very soft and dissolve in water.

Folklore gives them a quietly grounding, protective feeling, and links them with clearing away mental clutter — a good one to keep on a desk to sweep the cobwebs from a busy mind. Some traditions hold that each rose carries a guardian spirit. Never wet them, and dust gently — they're delicate.

Also known as Gembone, agatized dinosaur bone

Gembone is fossilised dinosaur bone in which the original bone has been replaced, cell by cell, with agate and other silica minerals — which means the honeycomb pattern you can see is the actual internal structure of the animal's bone, preserved in stone. The colours come from whatever minerals were in the groundwater: reds from iron, blacks from manganese. It's legally collected from private land in the American West.

It's kept as a profoundly grounding stone tied to endurance and ancestry, and it's hard to hold one without feeling the weight of the time involved. It polishes beautifully and makes an extraordinary talking point. Brief water contact only, as the matrix can be porous.

Dioptase produces small crystals of a green so saturated it has fooled people into thinking they'd found emerald — famously so in the eighteenth century, when a Central Asian find was sent to Moscow as emeralds and turned out to be something new entirely. The colour comes from copper, and the crystals are usually modest in size but jewel-bright, clustered on matrix.

It's regarded as one of the great heart stones, tied to emotional healing, forgiveness and starting again after grief or a long-held hurt. Its intensity suits that: this isn't a soft pastel comfort stone but something more vivid. Being copper-based and only moderately hard, keep it dry, handle it carefully, and wash your hands after long contact.

It forms in high-temperature metamorphic rock, with fine material from Brazil and Madagascar. The quartz-bound form is a comfortable 7 on the Mohs scale.

It's known as a patient, steadying stone — tied to calm confidence, focus and taking things one step at a time, working with the third eye and throat. It's a lovely companion when you're learning something new and need to keep your cool, and people often keep a piece by their books or study desk.

Also known as Green beryl

Emerald is the rich green variety of beryl, coloured by traces of chromium and vanadium, and treasured since antiquity — Cleopatra famously prized it. Most natural emeralds carry internal 'jardin' (garden) inclusions, and many are gently oiled to improve clarity, so they like careful handling despite their hardness. Fine material comes from Colombia, Zambia and Brazil.

It's the classic stone of the heart, love and loyalty — long linked with compassion, friendship and renewal, belonging to the heart chakra. It's a stone for cherished bonds and for keeping love growing, which is why it turns up so often in romantic tradition. Because emeralds are often oiled and included, keep them away from soaking and harsh cleaning.

Emerald in matrix is exactly what the name says: emerald crystals still embedded in the rock they grew in, usually white quartz or dark mica schist. It's a far more affordable way to own real emerald than a faceted gem, and arguably more interesting — you can see the hexagonal crystal shape and the geology that made it, rather than a cut stone divorced from its context.

It carries emerald's heart folklore — love, loyalty, growth — with an added note of patience and things developing in their own time, which suits a crystal still held in its birthplace. Beautiful on a shelf. The matrix is often softer than the crystals, so brief water contact and gentle handling.

Its folklore is unusual and worth knowing: it's thought to gently amplify whatever you already carry — which is why people like to pair it with kind intentions and a hopeful outlook rather than a bad mood. A heart-chakra stone, it's best kept close when you're feeling positive, on the idea that it gives back what you put in. Brief water contact only.

Eudialyte shows as raspberry-red patches scattered through a grey-green matrix, and comes chiefly from the Kola Peninsula in Russia and from Greenland — remote, cold places with unusual alkaline geology. Its name comes from Greek meaning 'easily dissolved', because it breaks down readily in acid, which is how mineralogists first distinguished it. Some material is very mildly radioactive at levels considered harmless in normal handling, though it's not a stone to sleep with under your pillow.

It has become known as a heart-and-root stone about following what you actually want — self-love, life purpose, and lining up your daily life with what matters to you. People reach for it when they feel they've drifted off course. Brief water contact, and store it as you would any specimen rather than carrying it constantly.

Fire agate gets its flashes of red, orange and green not from colour but from structure: microscopically thin layers of iron oxide within the chalcedony interfere with light, exactly as an oil film does on water. Cutting it is genuinely difficult, because the cutter must grind down to the fire layer without going through it, which is why good pieces command real prices.

It's kept as a courageous, protective stone with a warm, inner-fire character — often described as returning harm to sender in older folklore, though most people simply enjoy it as a confidence stone. It's tough, hard-wearing and fine with brief water contact.

It appeared on the market relatively recently, from Madagascar, and became popular almost immediately for obvious reasons.

Its folklore practically wrote itself: growth, potential, and blossoming into what you're becoming — a gentle encouragement stone rather than a dramatic one, sitting with the heart and root. It's a lovely gift for someone starting something new, or for anyone who needs reminding that they're further along than they think. Hard-wearing and fine with brief water contact.

It comes in dreamy ribbons of purple, green and blue, sometimes all in one 'rainbow' piece. It's soft (Mohs 4), so it wants gentle care; fine material comes from China, Mexico and the UK's own Blue John caverns.

It's long been loved as the stone of clear thinking — kept close for focus, tidy thoughts and a calm, ordered mind, working with the third eye and crown. It's a brilliant one for the desk or study when your head feels like a browser with too many tabs open. Two care notes: it can fade in sunlight, and being soft and sometimes porous, it's best kept dry.

Also known as Agatized coral, petoskey stone (related)

Fossil coral is ancient coral in which the original calcium carbonate has been slowly replaced by chalcedony, preserving the little flower-like patterns of each individual polyp — so what looks like a floral design is actually the architecture of a colony of animals. Florida and Indonesia produce the best-known material. Michigan's Petoskey stone is a related fossil coral, and that state's official stone.

It's kept for patience and gentle growth, and often for community — fitting, given that every pattern on it records thousands of tiny creatures living together. It's a lovely, quiet, unshowy stone. Being silica-replaced it's tough and takes brief water contact happily.

It's regarded as a soft, restoring stone — tied to resilience, gentle self-care and bouncing back after you've been giving a great deal, nourishing the heart. It's a lovely one to keep close when your own cup is running low. Because it's so soft and flaky, keep it dry and handle it kindly.

Also known as Lodolite, scenic quartz, shaman quartz, included quartz

Garden quartz isn't a mineral in its own right — it's clear quartz that grew around other minerals, trapping them inside like a landscape in a paperweight. Those drifting greens are usually chlorite, the rusty reds hematite, the soft clouds clay or feldspar, and because the quartz kept growing while they settled, each piece holds a scene no other piece can repeat. You'll hear it called lodolite (from the Spanish for mud), scenic quartz, or shaman quartz, all describing the same happy accident of geology.

People are drawn to it for exactly the reason it's named: it looks like a tiny world, and it invites you to look *into* something rather than at it. That makes it a favourite for meditation and for quiet, reflective moments — the folklore speaks of inner journeys, patient growth and finding your own way through. It's a lovely one to sit with when you want your thoughts to settle rather than race. Being quartz, it's hard-wearing and fine with brief water contact.

It forms as well-shaped crystals in metamorphic rock and is hard and durable, which is why it's been set into jewellery for thousands of years. Sources include India, Africa and Brazil.

It's a warm, energising stone of passion and vitality — long kept close for courage, devotion and a bit of inner fire when you need it, working with the root and the heart. Carry it when you want to feel more alive to things. Being hard and stable, it handles brief water contact without fuss.

Also known as Aventurine glass, monk's gold

Goldstone deserves an honest introduction: it's a man-made glass, not a mineral, created by melting silica with copper salts under controlled conditions so that tiny copper crystals form and glitter throughout. The technique is traditionally credited to Venetian glassmakers, and the legend of a monastic accident gave it the old name 'monk's gold'. Blue and purple versions use cobalt or manganese instead.

None of that stops it being lovely, and it's picked up a folklore of ambition and quiet drive — the glitter doing the talking. As long as it's sold honestly as glass, there's every reason to enjoy it. It's stable, durable and needs no special care.

Also known as Botryoidal chalcedony, purple grape chalcedony

Grape agate is botryoidal chalcedony — countless tiny spheres clustered together exactly like a bunch of grapes — found in Indonesia and usually a soft lilac-purple, though green and grey occur too. Despite the name it's not a banded agate; 'agate' is doing loose duty for chalcedony here. The little spheres formed as silica-rich fluid deposited in rounded layers rather than flat ones.

It's kept for calm and quiet reflection, associated with dreaming and inner stillness at the third eye and crown, and it's an undeniably charming thing to look at. Those spheres detach more easily than you'd expect, so handle it gently, keep water contact brief, and keep it out of strong sun to protect the colour.

Also known as Prase opal, Peruvian green opal

Green opal is the soft, opaque, non-flashing form of opal in a gentle sage or apple green, coloured by traces of nickel or included minerals. Most comes from Peru alongside the pink and blue material. Like all opal it contains water in its structure, so it must not be allowed to dry out abruptly or get hot.

It's kept as a renewing, balancing heart stone — steadying emotions and encouraging gentle recovery, rather than dramatic change. It has a calm, unhurried character. Keep it away from radiators, direct sun and hot cars, and don't soak it.

Also known as Rock salt, Himalayan salt crystal

Halite is simply rock salt in crystal form — the very same sodium chloride as the salt in your kitchen, grown into perfect cubes over millions of years as ancient seas evaporated. Pink Himalayan material gets its colour from iron; rare blue halite from structural defects in the crystal. It is completely water-soluble, which cannot be overstated: a wet halite is a puddle.

Salt has been used for cleansing and purification in almost every culture there is, and halite carries that straight through — clearing a space, clearing your head, and fresh starts. Keep it absolutely dry, away from humidity, and never wash it or leave it in a steamy room.

Also known as Haematite, bloodstone (old name)

Hematite is iron oxide, and it's surprisingly heavy for its size — pick one up and you can feel the iron. Polished, it takes on a bright silvery, mirror-like sheen; in raw form it can be reddish, and it's actually the source of the red in a great deal of the earth's soil and rock. Fine material comes from Brazil, the UK and the USA.

It's one of the great grounding stones, associated with feeling steady, protected and firmly rooted, sitting at the root chakra. Many people hold a tumbled piece when they feel scattered — its weight alone is oddly reassuring. One important care note: because it's iron-based it will rust, so keep it dry and out of water.

Also known as Herkimer quartz, double-terminated quartz

Herkimer 'diamonds' are not diamonds at all — they're exceptionally clear quartz crystals from Herkimer County in New York, and their fame comes from a quirk of how they grew. Sealed in pockets of dolomite for around half a billion years, they formed floating freely rather than attached to a wall, so they emerged with points at *both* ends and faces so bright they look cut and polished. Only stones from that area are true Herkimers, though similar double-terminated quartz comes from Pakistan, China and elsewhere and is often sold under the name.

Because they're pointed at both ends, tradition treats them as stones that both give and receive — amplifying whatever you bring, and bridging one thing to another. They're linked with mental clarity and, very commonly, with vivid dreaming; plenty of people keep one by the bed and report livelier nights. They're slightly harder than ordinary quartz and wonderfully durable, so an unset one takes everyday handling without complaint.

Heulandite forms as pearly, coffin-shaped plates in soft peach, white and green, usually in the same Indian basalt cavities that produce stilbite and apophyllite. Like all zeolites it has a porous internal structure that naturally holds water, which is both why it's industrially useful and why specimens should be kept dry.

It's kept for letting go — of grudges, of old attachments, of the version of a story you've been telling yourself — and for a general sense of peace, sitting with the heart and crown. It pairs beautifully with stilbite in a quiet corner of a room. Soft and fragile, so it wants a shelf rather than a pocket.

Also known as Green kunzite, green spodumene

Hiddenite is the green variety of spodumene, the same mineral as pink kunzite, coloured by chromium. It was discovered in North Carolina in the 1870s and named after the mineralogist who identified it; fine material remains genuinely rare, and much 'hiddenite' on the market is really pale green spodumene without the chromium colouring.

Like kunzite it's a lithium mineral with a tender, heart-centred reputation — gratitude, gentle healing and new growth after loss. Where kunzite is about receiving love, hiddenite is more often linked with appreciating what's already there. It fades in sunlight, so keep it shaded, and handle it carefully as spodumene cleaves easily.

Also known as Golden calcite, amber calcite

Honey calcite is calcium carbonate in a warm golden-amber, glowing beautifully when light passes through it. Like all calcite it's soft — you can scratch it with a coin — and reacts to acid and water, so it's a keep-dry, handle-kindly stone. Good clear material shows calcite's famous double refraction, where a line viewed through it appears twice.

It's associated with steady confidence and motivation, the sort that builds rather than surges — a solar plexus stone for anyone rebuilding self-belief after a knock. Its colour makes it a lovely thing to keep on a desk in winter. Cleanse it with sound or smoke, never water.

Also known as White buffalo stone, magnesite (often confused)

Howlite is a white borate mineral, marbled with soft grey veins that make it look a little like marble itself. It's quite soft and porous, which is why it's so often dyed to imitate turquoise (dyed blue howlite is very common) — natural howlite is white. It comes from the USA and Canada.

It's one of the calmest stones of all, traditionally kept close for a quiet mind, patience and easier, more restful sleep, working with the crown. A popular way to use it is to tuck a piece under the pillow, or to hold it when patience is wearing thin, as it seems to take the heat out of a moment. Being porous, keep it dry so it doesn't absorb water or dye.

Hypersthene is a dark member of the pyroxene family with a subtle silvery sheen from tiny internal inclusions. It forms in igneous and metamorphic rock and is usually cut into tumbles and palm stones; good material comes from Canada and Norway. It's a moderately hard, keep-dry sort of stone.

It's associated with calm decisiveness and a quiet, grounded clarity when you've a lot on your mind, working with the root and third eye. It's a good one to hold when you need to make a choice and stop going round in circles. A quietly practical stone rather than a showy one.

It's reasonably hard and comes from India, Sri Lanka and Brazil.

Fittingly, it's known as the stone of inner vision — long associated with gentle guidance, balance and finding your way through when things feel foggy, belonging to the third eye. People keep it close when they've lost their bearings a little and would like to feel pointed the right way. Brief water contact is fine.

It has been treasured across the world, but especially in China and among the Māori and Mesoamerican peoples, for thousands of years, carved into everything from tools to talismans. Sources include Myanmar, China and Canada.

It carries a feeling of good fortune, harmony and calm — a steady, lucky companion, working with the heart chakra. Long kept close to invite wellbeing and gentle prosperity into a home, it's often passed down through families. Being tough, it handles brief water contact well.

Also known as Sea jasper, orbicular jasper

Ocean jasper is an orbicular jasper — a chalcedony that grew in little spherical clusters, giving those charming 'orbs' of green, pink and cream. It famously comes from a single coastal deposit in Madagascar, some of it only reachable at low tide, which adds to its appeal. It's tough and polishes beautifully.

Its gentle, watery patterning suits its folklore: a stone of going with the flow and finding a bit of joy in the everyday, soothing the heart and solar plexus. It's a calming, happy little companion for anxious days, and people often keep a tumbled piece simply because it's cheerful to look at. Brief water contact is fine.

Fine material comes from South Africa and the USA. It's tough and takes a lovely polish that shows off those 'scenes'.

It's a comforting, grounding stone, long linked with calm, safety and a deep connection to the earth, working with the root. Hold a piece and you can almost feel the wide, quiet outdoors in your hand — it's a favourite for anyone who finds peace in nature. Everyday water contact is fine.

Red jasper is an opaque chalcedony coloured a deep brick-red by iron oxide. It's one of the oldest known ornamental stones, tough and even-textured, taking a smooth matte-to-glossy polish; it's found in India, Brazil and, really, worldwide.

It's a wonderfully grounding, steadying stone, kept close for strength, endurance and a feeling of being firmly supported, sitting solidly at the root. It's a good one for the long haul — think of it as quiet stamina in your pocket, and a favourite of anyone who needs to pace themselves through a demanding stretch. Everyday water contact is fine.

Also known as Whitby jet, Yorkshire jet, black amber

Jet is not a mineral but fossilised wood — ancient trees compressed over millions of years into a light, velvety-black material that can be polished to a deep shine (the very origin of the phrase 'jet black'). Whitby in Yorkshire is its most famous source, and it became hugely popular in Victorian mourning jewellery.

That history threads into its folklore: a protective, comforting stone, kept close through grief and to soak up heavy feelings, deeply grounding at the root. It's a tender, old-soul sort of stone for hard chapters. Being soft and organic, keep it dry and out of strong sun so it doesn't dry out.

Also known as K2 jasper, azurite in granite, raindrop azurite

K2 stone is a pale granite dotted with vivid blue orbs of azurite, found high in the Karakoram range near K2 itself — which is where the name comes from, and why supply is limited by the same brutal seasons that limit mountaineering. It's frequently mislabelled 'K2 jasper', though there's no jasper in it whatsoever; it's granite with copper mineralisation.

Folklore reads the pairing as granite's grounding steadiness carrying azurite's insight — clear thinking without losing your footing, at the third eye and crown. It's a genuinely distinctive-looking stone and a good talking point. The azurite spots are soft and copper-based, so keep it dry and out of harsh sun.

Also known as Kambaba stone, green stromatolite jasper

Kambaba jasper isn't really a jasper — it's a fossil stromatolite, formed from mats of blue-green algae that lived billions of years ago, layered and mineralised into stone. Those dark orbs and swirls are the colonies themselves, preserved in cross-section. That makes it one of the oldest records of life on earth you can hold in your hand, which rather outclasses its humble green appearance.

It's kept as a calming, nourishing stone — associated with steady growth, patience and a sort of deep biological reassurance, sitting with the heart and root. People often describe it as grounding without being heavy. It's tough enough for everyday handling and takes a lovely soft-sheen polish.

Also known as Chrome clinochlore

Kammererite is a chromium-bearing chlorite in a violet-magenta so rich it looks almost artificial, forming tiny platy crystals usually on a chrome ore matrix. Most fine specimens come from Turkey, and because it's exceptionally soft — around 2 on the Mohs scale — good crystals are fragile and highly collectable. It's related to seraphinite, which is the same family in green.

Its folklore is about gentle spiritual transformation and insight, a crown-and-third-eye stone with a soft rather than forceful character. Chiefly, though, it's admired: that colour is one of the great sights in mineralogy. Keep it dry, dust-free and untouched in a cabinet.

Also known as Pink spodumene

It's a lithium mineral (the same calming element used in some mood medicines), and importantly its colour fades in sunlight, so it's a keep-shaded stone. Fine material comes from Afghanistan, Brazil and the USA.

It's a very sweet, heart-soft stone, associated with gentle love, emotional healing and letting your guard down safely, purely a heart-chakra stone. People keep it close when they're learning to trust again. Protect it from strong sun, which will slowly pale that lovely pink.

Also known as Disthene, cyanite

Kyanite forms in striking blades of sky-blue, and it has a fascinating quirk — its hardness differs dramatically depending on which direction you scratch it (around 4.5 along the blade, 7 across), which is why its name comes from a word tied to that very property. It grows in metamorphic rock, with fine blue material from Brazil, Nepal and the USA.

It's one of the few stones said never to need cleansing, on the idea that it doesn't hold onto negativity — which makes it a favourite for keeping alongside other crystals. Long tied to calm, clear communication and smooth, honest connection, it belongs to the throat and third eye. Being bladed, keep it out of water, which can seep into its layers.

Labradorite looks like a plain grey feldspar until the light strikes it just so — then it flashes brilliant blue, green and gold in an effect called labradorescence, caused by light bouncing between microscopic internal layers. First found in Labrador, Canada, its finest material now comes from Madagascar and Finland. It's a moderately hard, slightly flaky stone.

Little wonder it's the great magical stone — traditionally kept close for protection, intuition and a bit of everyday wonder, working with the third eye and crown. Turn a polished piece slowly in the light and you'll understand why it's so loved. It can be flaky, so brief water contact only, and handle the edges gently.

Lapis lazuli is a rock rather than a single mineral — mostly deep-blue lazurite, flecked with gold pyrite and white calcite — and it has been treasured since antiquity, ground into the priceless 'ultramarine' pigment of Renaissance painters and buried with the pharaohs. The finest still comes from the same ancient mines in Afghanistan.

It's a stone of wisdom and truth — long treasured for insight, honest expression and a quiet inner authority, sitting with the throat and third eye. It's a regal, clarifying companion for the thinker and the truth-teller. Because it contains pyrite and calcite, keep it dry — water can harm both.

Its dreamy blue, marbled with white, is coloured by traces of copper. It's moderately soft and fades in sun.

It's one of the most soothing stones there is, associated with calm, cooling tempers and the peaceful feeling of the sea, belonging to the throat chakra. People hold it when they need to bring their temperature down, inside and out. Keep it out of prolonged sun, which can pale its colour, and avoid soaking.

Also known as Black moonstone, Norwegian moonstone, blue pearl granite

Larvikite is a handsome dark rock from the Larvik region of Norway, packed with feldspar crystals that flash silvery-blue as you turn them — the same optical trick as labradorite, in a stone so durable it's used to clad buildings. You've almost certainly walked past a polished larvikite shopfront without knowing it. It's frequently sold as 'black moonstone', which is a trade name rather than a mineral description.

It's kept as a grounding, protective stone with a clear-headed streak — folklore ties it to seeing situations plainly and making decisions without drama. That combination of solidity and quiet shimmer suits it. Being a tough rock it handles everyday life easily, though brief water contact is the safer habit.

Also known as Basalt, volcanic rock

Lava stone is basalt — molten rock that erupted, cooled and froze full of tiny gas holes, giving it that light, porous, matte-black character. It's found wherever there's been volcanism, and because it's absorbent it makes a wonderful diffuser: add a drop of essential oil and it holds the scent for hours.

It's a deeply grounding stone, kept close for courage and steadiness, rooted at the base chakra — fittingly, given its fiery birth. A very popular way to use it is as a bracelet you can scent with a calming oil, so it's both a grounding stone and a little wearable aromatherapy. Being porous it dries slowly, so brief water contact only.

Also known as Lemurian seed crystal

Lemurian quartz is clear quartz with distinctive horizontal ridges up its sides, like the rungs of a ladder — a natural growth feature. First found in Brazil, it gathered a gentle modern folklore around the idea of running your thumb up those 'steps' as a focus for meditation.

It's regarded as a gentle, meditative stone, tied to quiet reflection and a feeling of connection, reaching for the crown and working across all the chakras like clear quartz. The classic way to use it is exactly that: hold it, run a thumb up the ridges, and let your mind settle. Being quartz, brief water contact is fine.

Lepidolite is a lilac mica naturally rich in lithium — the very element used in some mood-stabilising medicines — which is part of why it has earned such a calming reputation. It's soft and flaky, sometimes sparkling with tiny mica sheets, and comes from Brazil, the USA and Madagascar.

It's perhaps the great stone for peace of mind — long kept close to ease worry, soothe the nerves and settle a racing heart, working with the crown, third eye and heart. It's a wonderful one to hold when anxiety creeps in, and many keep a piece by the bed. Because it's soft and flaky, keep it dry and handle it gently.

Also known as Lodestone (when magnetic)

Magnetite is the most magnetic naturally occurring mineral on Earth, and naturally magnetised pieces — lodestones — were the world's first compasses, guiding navigation for centuries before anyone understood why. Remarkably, magnetite crystals occur inside the bodies of some migratory birds and bacteria, apparently helping them sense direction.

Its folklore follows the physics: grounding, and the idea of attracting what you're aiming for. It's a favourite for anyone working on drawing something into their life. Being iron, it rusts readily, so keep it bone dry, and store it away from anything a magnet could damage.

Also known as Mountain mahogany obsidian

Mahogany obsidian is volcanic glass mottled with rich red-brown patches, the colour coming from iron oxides caught in the melt as it cooled. It has all the glassy character of black obsidian with a warmer, earthier look, and it takes a beautiful polish — carvers love it for figures and freeforms.

It's considered the gentler, more grounding face of obsidian — strength, steadiness, and quietly releasing patterns you've outgrown, working at the root and sacral. Where black obsidian can feel confrontational, this one is usually described as supportive. Tough and easy to care for, with brief water contact fine.

Malachite is a copper carbonate with mesmerising bands of green, formed as copper-rich water deposited layer after layer in caverns and cavities. It's been used as a pigment and an ornamental stone for millennia, though its copper content makes its dust toxic — so it's kept as smooth, sealed, polished pieces and handled with clean hands. Fine material comes from the Congo, Russia and Zambia.

It's a bold, protective stone of change — traditionally kept close during transformation, and thought to draw off what you're ready to release, working powerfully with the heart chakra. It's a good one when you're ready for something to shift, though folklore says it likes to be treated with respect. Never soak it or drink water it's touched, and wash hands after long handling.

Also known as Pink calcite, manganoan calcite

Mangano calcite is a soft, sugary-pink calcium carbonate, its gentle colour coming from manganese, and it often glows a soft red under UV light. Like all calcite it's soft (Mohs 3) and water-reactive, so it's a keep-dry stone; fine pink material comes from Peru.

It's one of the sweetest heart stones, associated with gentle self-love, comfort and a very soothing, forgiving feeling, wholly a heart-chakra stone. People keep it close when they need to be a little kinder to themselves, and it's a favourite gift for someone going through a tender time. Its pink can fade in sun, and it dislikes water, so shade and dryness suit it.

Also known as Vltavin, Czech tektite

Moldavite is a genuine oddity — a green natural glass (a tektite) formed around fifteen million years ago when a meteorite slammed into what's now the Czech Republic, melting earth and sky together. That means it's quite literally not entirely of this world, and its supply is limited to that one strewn field, so real pieces are increasingly rare and often faked.

Its folklore matches its dramatic origin: an intense stone of change, treasured by those who feel ready for a shake-up and a fresh chapter, reaching from the heart to the crown. It's not the gentlest of stones — many describe a real 'buzz' from it — but a thrilling one for a turning point. Being glass, it's stable, though its rarity means it's best handled with care.

Mookaite is an Australian jasper (a radiolarite, formed from the silica shells of tiny ancient sea creatures) in earthy swirls of red, yellow and mustard. It comes from the Mooka Creek area of Western Australia, which gives it its name, and it's tough and takes a warm polish.

It's a lively, grounding stone, traditionally linked with adventure, vitality and making the most of the day in front of you, working with the root and sacral. It's a good one to carry when you want to say yes to things and shake off a rut. Being a quartz, everyday water contact is fine.

Moonstone is a feldspar with a soft, floating inner glow called adularescence, caused by light scattering between microscopic layers — the effect that gives it its milky, moonlit look. Fine material, including the rainbow-flashing kind, comes from Sri Lanka and India. It's moderately soft and a touch flaky.

It's a gentle, intuitive stone of new beginnings — long loved for calm, natural cycles and quiet hope, sitting with the crown and sacral. Traditionally tied to the moon and its rhythms, it's a tender companion for fresh starts and following your instincts. Charge it under the full moon if you like, but keep water contact brief, as it can be flaky.

It's tough, takes a lovely polish, and comes from India and the USA. Despite the name it isn't strictly a banded agate, but the name has stuck.

It's truly the gardener's stone — associated with growth, new starts, abundance and a deep, calming bond with nature, working with the heart chakra. People keep one with their seeds or their plans, on the idea that it encourages things to quietly flourish. Being quartz, brief water contact is fine.

Also known as Nuummit, magician's stone

Nuummite is one of the oldest rocks used as a gemstone — roughly three billion years old — and comes from a single remote area near Nuuk in Greenland, mined by hand in short summer windows. Its darkness is scattered with needle-like crystals that flash gold, copper and green as the light moves, an effect quite unlike anything else. Genuine material is scarce and priced accordingly, so bargain 'nuummite' is worth a second look.

It's earned a formidable reputation as a stone of personal power and protection, often called the sorcerer's or magician's stone, and it's associated with honest self-knowledge — the kind of stone folklore says will show you yourself rather than flatter you. People tend to describe it as intense rather than gentle. Keep water contact brief and it will hold that flash for a lifetime.

Also known as Snowflake obsidian, flowering obsidian

Snowflake obsidian is black volcanic glass dusted with soft grey-white flecks — those 'snowflakes' are little radiating clusters of the mineral cristobalite that began to crystallise within the glass as it slowly cooled. It's found in the USA and Mexico, and it polishes to a striking contrast.

It's a gently grounding, balancing stone, kept close for calm, perspective and finding the light in darker moments, rooted at the base — a softer, more contemplative cousin of pure black obsidian. It's a kind, level-headed sort of companion, and a good one for steadying yourself after a rough patch. Brief water contact is fine.

They're famously tempting to touch and famously easy to ruin — the fibres crush permanently under a fingertip, so admire with your eyes.

Its folklore is one of gentleness and comfort, fresh starts and being kind to yourself, and its appearance does most of the persuading. Keep it in a display case away from dust and dry air currents, never wash it, and never, ever stroke it.

It's tough, takes a mirror polish, and has been carved into cameos and seals since antiquity.

It's a strong, steadying stone of self-control and protection — long kept close for willpower, focus and a feeling of being firmly anchored, sitting solidly at the root. It's a good one when you need to hold your nerve and see something through — a favourite for exams, deadlines and difficult stretches. Being quartz, brief water contact is fine.

Opal is a hydrated silica — it actually contains water within its structure — and precious opal's famous play of colour comes from light diffracting through microscopic spheres of silica packed inside. That water content is key to its care: if an opal dries out too much it can craze and crack. Fine material comes from Australia, Ethiopia and Mexico.

It's a dreamy, emotional stone, tied to inspiration, imagination and tender feelings gently brought to the surface, touching every chakra in its shifting colour. It's a stone for the sensitive and the creative. Keep it away from heat and prolonged dryness, and don't soak or scrub it — gentle care keeps that inner fire alive.

Opalite is worth being honest about: it's a man-made opalescent glass, not a natural stone, with a milky body that glows warm or cool depending on the light behind it. It's inexpensive and pretty, and there's nothing wrong with it — it's just good to know it comes from a furnace rather than the earth.

People give it a gentle folklore all the same — associated with calm, smooth transitions and a bit of quiet optimism, working softly across the upper chakras. It's an easygoing, undemanding stone for everyday calm. Being glass, it's stable and fine with brief water contact.

Also known as Iceland spar, clear calcite

Optical calcite, or Iceland spar, is clear calcite that splits light into two separate rays — put it over a line of text and you see the text twice, cleanly doubled. That property, called birefringence, made it genuinely important to the history of optics, and there's a persuasive theory that Viking navigators used it as a 'sunstone' to locate the sun through cloud. Its perfect rhomb shape comes from calcite's cleavage, not from cutting.

Predictably, its folklore is about clarity and seeing more than one truth in a situation — a good one for anyone stuck between two views of the same problem. It's also simply a wonderful thing to show people. Soft and soluble, so keep it dry and away from harder stones.

Also known as Orthoceras fossil, straight-shelled nautiloid

Orthoceras were squid-like creatures with long straight cone-shaped shells that lived some four hundred million years ago — even older than the ammonites they're often sold beside. Almost all of the polished material comes from Morocco, where fossil beds are cut and polished into plates, dishes and towers; the pale segmented shapes against the near-black limestone make them look almost like a design rather than a fossil.

They're kept as grounding, steadying pieces, tied to patience and to a sense of deep time — a handsome desk object with a genuinely humbling backstory. Because the matrix is limestone, they're soft and water-reactive: dust them, don't wash them, and they'll keep their polish for decades.

Also known as Apricot moonstone

Peach moonstone is moonstone coloured a warm apricot by traces of iron, with the same soft floating adularescence that gives all moonstone its glow. It's usually cut as smooth cabochons and tumbles, since the effect depends entirely on a domed surface catching the light.

Where white moonstone is associated with intuition and cycles, the peach is kept for gentle confidence and self-acceptance — being kind to yourself about being a work in progress, sitting with the sacral and heart. It's a comforting rather than mystical stone. Being feldspar it can flake along its cleavage, so handle it gently and keep water contact brief.

It's a warm, uplifting stone linked with renewal, gratitude and letting go of old resentment to make room for good things, belonging to the heart. People keep it close when they're ready to forgive and move on a little lighter. It's reasonably durable, but brief water contact is best.

Deeply grounding and patient in feeling, it's associated with steadiness, roots and taking the long, calm view, firmly a root-chakra stone.

Pink opal is the soft, opaque, non-flashing cousin of precious opal — hydrated silica coloured a gentle pink, mostly from Peru, and prized for its calm, chalky, almost porcelain look. Like all opal it holds water within its structure, which means it can craze or crack if it dries out or is subjected to heat, so it needs a little consideration.

It's one of the tenderest heart stones, associated with gentle emotional healing, quietness and self-kindness, and it's often recommended for anyone who's been running on empty. There's nothing loud about it. Keep it away from radiators, hot cars and direct sun, don't soak it, and it will keep its soft glow.

Prehnite is a soft green-yellow silicate, often beautifully translucent with fine internal needles of black tourmaline or epidote. It was one of the first minerals ever named after a person (an 18th-century Dutch colonel), and fine material comes from South Africa, Australia and Mali.

It's a very soothing, hopeful stone, kept close for calm, healing and quieting an overactive mind, working with the heart and solar plexus. It's lovely to hold when you simply can't switch off — some call it the stone for 'healing the healer'. Brief water contact only.

Prehnite with epidote is the classic combination: soft, glowing green-yellow prehnite threaded through with dark green or black needles of epidote, usually from Mali. The needles grew first and the prehnite formed around them, so the effect is of grass or pine needles suspended in resin. Similar-looking material with black tourmaline needles is also common.

It's kept as a healing, quieting stone — prehnite's calm with epidote's tendency to amplify whatever you bring, so folklore advises approaching it in a good frame of mind. It's very popular for meditation and for anyone who struggles to switch off. Brief water contact only.

Also known as Stonehenge bluestone, dolerite

Preseli bluestone is the rock that makes up the inner ring of Stonehenge — spotted dolerite quarried in the Preseli Hills of Pembrokeshire and somehow transported around 150 miles to Salisbury Plain roughly five thousand years ago, a feat archaeologists still argue about. It's a dense blue-grey igneous rock flecked with pale feldspar, and it rings when struck, which some researchers think may be why it was chosen.

Naturally, it has become a stone of ancestry, deep grounding and standing firm — you'd struggle to find a British stone with more history packed into it. It appeals to anyone drawn to the old places. Hard-wearing and easy to keep, with brief water contact fine.

Prophecy stone is a rugged, metallic stone from the Sahara in Egypt — a natural mix of iron minerals (limonite, hematite and sometimes marcasite) with real weight and character. Because it's iron-based, it will rust, so it's very much a keep-dry stone. Each piece has an unusual, almost sculptural shape.

It's a grounding, focusing companion, kept close for reflection and a settled, present feeling, rooting you firmly. It's a good one for coming back to the here and now when your mind has wandered off. Keep it away from water so it doesn't rust.

Purpurite is a manganese phosphate with a violet so deep and slightly metallic that it barely looks mineral at all. That colour develops as the surface oxidises, so freshly broken material can look duller and brightens with exposure. It's fairly soft and comes mostly from Namibia, usually as rough chunks and tumbles rather than crystals.

Its folklore is about breaking out of a rut — confidence, speaking up, and shedding habits that no longer serve you, sitting with the third eye and crown. It's a good one for anyone who's been staying quiet for too long. Keep it dry and out of harsh light, and store it separately as its softness makes it scratch easily.

Also known as Fool's gold, iron pyrites

Pyrite is iron sulphide, the famous 'fool's gold' — its brassy, metallic cubes fooled many a prospector, though there's nothing foolish about the mineral itself. It forms remarkably perfect cube shapes in nature, especially the prized specimens from Spain. It will slowly tarnish and can react to damp, so it likes to be kept dry.

It's a bright, confident stone of abundance, willpower and protection, kept close to invite a bit of prosperity and shield your good energy, belonging to the solar plexus. Keep it where you work or plan — it's a proper little powerhouse, and a classic on the desk of anyone chasing a goal. Never soak it; damp makes it rust and can release a little sulphur.

Also known as Llanite, vulcanite, Rainforest rhyolite

Que sera (also called llanite or 'vulcanite') is a speckled volcanic rock — a mix of quartz, feldspar and other minerals in soft greys, blues and pinks — with a wonderfully easygoing feel. Much of it comes from Brazil. Its name, from the phrase 'whatever will be', says almost everything about its reputation.

It's associated with going with the flow, wellbeing and a calm, 'whatever will be' outlook, balancing gently across the chakras. It's a brilliant one for anyone who worries about things they can't control — people keep a piece as a small, tangible permission to let go. Being largely quartz-based, brief water contact is fine.

Also known as White labradorite

Here's a lovely bit of mineral honesty: rainbow moonstone is not, strictly speaking, moonstone at all — it's a white variety of labradorite, and its blue flash is labradorescence rather than the softer adularescence of true moonstone. The trade name stuck because the effect is so moon-like, and it's now far better known than the correct one. Held to the light and tilted, good material throws blue, and sometimes flickers of gold and violet too.

It carries all the moonstone associations — intuition, new beginnings, emotional steadiness, the pull of natural cycles — with an extra reputation for lifting the mood, thanks to those rainbow flashes. It's a favourite for anyone starting something, or wanting to trust their gut a bit more. Being feldspar it can cleave along its layers, so treat it gently and keep water contact brief.

Also known as Sheen obsidian, iris obsidian

Rainbow obsidian looks like plain black glass until you catch it in strong directional light — then bands of green, purple and gold sweep across the surface, caused by microscopic layers of mineral inclusions scattering light as it passes. Cutters have to orient the stone very precisely to bring the effect out, which is why well-cut pieces cost more than they might seem to warrant.

Its folklore leans on that hidden light: hope, finding the good in a dark stretch, and releasing what hurts without being overwhelmed by it. It's often given to someone going through something heavy, as a small, beautiful argument that colour is still there. Durable and easy to keep — just make sure to view it in good light.

Red tiger's eye is golden tiger's eye whose iron content has been oxidised to a deep reddish-brown — sometimes naturally, and often by gentle heat treatment, which is a long-standing and accepted practice in the trade. The silky chatoyant band remains, glowing across a much warmer body colour.

It's the most fiery of the tiger's eye family, kept for vitality, motivation and physical confidence, working at the root and sacral. People reach for it when energy is flagging or when they need to stop deliberating and act. Tough, durable and fine with brief water contact — an easy everyday stone.

Rhodochrosite is a manganese carbonate in bands of rosy pink and cream, its colour coming straight from the manganese. It's soft (Mohs 3.5–4) and water-reactive, so it's a keep-dry stone; the finest banded material comes from Argentina, with superb crystals from Peru and the USA.

It's a warm, tender heart stone, traditionally kept close for self-love, healing old hurts and rediscovering a bit of joy, purely a heart-chakra stone. It's a comforting companion when you're learning to be gentle with yourself. Its pink can fade in sun and it dislikes water, so keep it shaded and dry.

Rhodonite is a rosy-pink manganese silicate, usually veined with black manganese oxide that makes a lovely contrast. It's harder and more durable than its cousin rhodochrosite, and comes from Russia, Australia and Brazil, taking a smooth, warm polish.

It's a compassionate, balancing stone, long associated with emotional healing, forgiveness and steadying the heart, working with the heart chakra. It's a good one for making peace — with others, and with the past — and is sometimes called the 'rescue stone' for its comforting, steadying feel. Brief water contact only.

Rhyolite is a fine-grained volcanic rock — the extrusive cousin of granite — often beautifully patterned in greens and earthy tones (rainforest jasper is a well-known variety). It forms from silica-rich lava that cooled quickly at the surface, and comes from Australia, the USA and Mexico.

It's a grounding, encouraging stone, linked with self-worth, resolve and moving gently forward, working with the root and heart. People keep it close when they're rebuilding their confidence or need a nudge to keep going. Being largely silica, brief water contact is fine.

Rose quartz is the tender pink variety of quartz, its soft colour usually attributed to tiny mineral inclusions rather than a single element. It forms in massive, cloudy pieces rather than clear points, which suits its gentle character, and it comes from Brazil, Madagascar and India — it's one of the most popular stones on earth.

It's the great stone of the heart — associated with love in every form, kindness, comfort and gentle self-care above all else, wholly a heart-chakra stone. Keeping a piece by the bed or over the heart is the classic way to use it; it's the softest, kindest stone there is. One care note: its pink fades to near-white in strong sunlight, so it's happiest in a shaded spot.

Also known as Red corundum

Ruby is red corundum — the same mineral as sapphire, coloured by chromium — and at 9 on the Mohs scale it's one of the hardest gems there is, second only to diamond. That toughness and its glowing red have made it a symbol of passion and royalty for millennia. Fine material comes from Myanmar, Thailand and across Africa.

It's a passionate, vital stone of love and courage — long treasured for warmth, confidence and a bit of noble fire, working with the root and the heart. It's a stone for living wholeheartedly. Being extremely hard, it's happy with everyday water contact.

Also known as Ruby fuchsite

Ruby in fuchsite pairs raspberry-red corundum crystals with shimmering emerald-green fuchsite mica, and the hardness gap between them is remarkable — the ruby is a 9 on the Mohs scale, the fuchsite as soft as 2. That means the stone as a whole must be treated as the soft one: it flakes and scratches easily along the mica.

Its folklore is a pleasing balance: ruby's courage and vitality softened by fuchsite's nurturing, restorative quality — strength that doesn't harden you, sitting squarely with the heart. It's often recommended for carers and anyone who gives a lot. Keep it dry and stored away from harder stones.

Ruby in kyanite pairs raspberry corundum crystals with blue-grey bladed kyanite, often with black or green mineral streaks running through. It's a striking natural combination and a good deal less common than ruby in zoisite, mostly coming from India and Tanzania.

Folklore reads it as ruby's fire held in kyanite's calm, clear channel — passion that stays articulate rather than boiling over, working across the heart and throat. It's a good one for anyone who cares deeply and struggles to say so calmly. Kyanite is bladed and lets water into its layers, so keep it dry and handle the edges gently.

Also known as Anyolite, ruby zoisite

Ruby in zoisite — properly called anyolite — is a striking natural combination: opaque green zoisite studded with raspberry-red ruby crystals and streaked with black hornblende. It comes from Tanzania, from the same geological region that gave us tanzanite, and it's usually carved into figures and freeforms because the colour contrast is so bold. The rubies are real corundum, just of ornamental rather than gem quality.

Folklore reads the pairing as ruby's fire tempered by zoisite's growth and calm — vitality without burnout, courage without recklessness, working across the heart and root. It's a good one for anyone who runs hot and needs to pace themselves, or who's rebuilding energy after a hard stretch. Tough enough for everyday handling, with brief water contact.

Rutilated quartz is clear quartz threaded with fine golden needles of the mineral rutile (titanium dioxide) — those glinting strands grew inside the quartz as it formed, and no two patterns are alike. Fine material comes from Brazil, where it's sometimes called 'angel hair' or 'Venus hair' quartz.

It's a bright, uplifting stone, traditionally thought to lift the mood and gently illuminate a way forward, working with the crown and solar plexus. It's a lovely one when you feel stuck in the dark and want a little light let in. Being quartz, brief water contact is fine.

Sapphire is corundum — the same mineral as ruby, simply any colour other than red. Blue is the famous one, coloured by traces of iron and titanium, but sapphire also comes in yellow, pink, green and the rare peachy padparadscha. At 9 on the Mohs scale it's second only to diamond among natural gems, which is why it wears so well in rings worn daily for decades.

Historically it's the stone of wisdom, integrity and clear judgement, long associated with royalty, clergy and oath-taking — a stone for meaning what you say. It's linked with calm, focused thinking at the third eye and throat. Being extremely hard and stable, it's about as low-maintenance as a gemstone gets.

Sardonyx is a banded chalcedony combining the reddish-brown of sard with the white of onyx in handsome, even layers — a stone the Romans carved into seals and cameos precisely because those layers cut so cleanly. It's tough and takes a fine polish; much comes from India and Brazil.

It's a steady, protective stone, long tied to strength, willpower and happy, lasting bonds, rooting at the base. It's a quietly reliable companion for commitments and long friendships, and was traditionally exchanged as a token of loyalty. Being quartz, everyday water contact is fine.

Scolecite is a zeolite — a family of minerals full of microscopic channels that hold water — forming delicate white sprays and blades with a wonderfully peaceful feeling. Fine specimens come from India. Because zeolites hold water within their structure, it's best kept dry.

It's a gentle, high-hearted stone, tied to inner peace, restful sleep and calm connection, reaching for the crown. It's a beautiful one to keep where you rest, and a favourite for meditation for the serene atmosphere it seems to lend. Keep it dry to protect its structure.

It's very soft (Mohs 2 — you can scratch it with a fingernail) and, crucially, it dissolves in water, so it must be kept completely dry. Fine material comes from Morocco, Mexico and the USA.

It's beloved as a cleansing, peaceful stone — kept close to clear the air, bring calm and gently refresh your other crystals too, belonging to the crown. The classic way to use it is as a charging plate: rest your tired stones on a piece of selenite overnight and it's said to reset them. Just never, ever get it wet.

That three-part structure gives it its beautiful patterned look. Fine material comes from Madagascar and the USA.

It's a nurturing, grounding companion, linked with patience, calm and feeling supported, rooting and warming at once. It's a comforting stone for when you need to feel held, and its earthy pattern makes it a lovely one to keep on a desk. As it contains calcite, keep it dry.

Also known as Serafina, silver-leaf chlorite

Seraphinite is a green chlorite mineral from one remote deposit in Siberia, and its charm is entirely in the silvery feathering that spreads across the dark green like frost or plumage — hence the name, after the seraphim. Those patterns are fibrous mica-like crystals catching the light. It's very soft, around the hardness of a fingernail, so it's cut into cabochons and palm stones rather than anything that gets knocked about.

Its folklore is unusually tender: renewal, gentle healing, and a feeling of being looked after, working with the heart and crown. It's a favourite among people who want something calming rather than energising. Because it's so soft, keep it dry, store it away from harder stones, and it will keep those feathers looking beautiful.

It ranges from soft to moderately hard, and some fibrous varieties should simply be admired rather than handled roughly. It's found worldwide.

It's an earthy, restoring stone, tied to renewal, gentle energy and a feeling of coming back to yourself, working with the heart. It's nice to hold when you'd like to feel refreshed and a little more like you again. Brief water contact only, and choose smooth, solid polished pieces.

Also known as Fossil shark tooth

A fossil shark tooth is enamel and dentine that has slowly mineralised over millions of years, which is why they survive when the rest of the animal doesn't — sharks shed thousands of teeth in a lifetime, so the seabed is scattered with them. Colour comes from the sediment they lay in: black, grey, brown, sometimes blue-ish. They belong to the apatite family, the same mineral family as our own teeth, which is a neat detail.

Carried for protection and courage more or less everywhere sharks are found, they've long been a talisman for facing something you'd rather not. There's something bracing about holding one — it's a survivor's object, from an animal that has outlasted several mass extinctions. Reasonably hard and easy to keep, though brief water contact is best on fossil material.
