Ametrine7 Mohs · quartz · solar-plexus, third-eye, crownIt is one crystal wearing two colours. Purple at one end, gold at the other, grown that way underground. The tell is the seam. Natural…
Ammonite3.5-4.5 Mohs · organic · root, crownThis was an animal. It swam, it died out with the dinosaurs, and it sank into seabed mud. The mud turned to rock and swapped the shell…
Angelite3.5 Mohs · sulphate · throat, third-eye, crownAngelite is a salt left behind where an ancient sea dried up. Burial and heat drove the water out of it. It wants that water back. Leave…
Apache Tears5-6 Mohs · volcanic glass · root, heartIt is not a stone. It is glass, lava that cooled too fast to become anything else. Hold one up to a lamp. The whole pebble glows smoky…
Aquamarine7.5-8 Mohs · silicate · throat, heartNearly every blue aquamarine in a shop window has been in an oven, at around 400 degrees, to burn the green out. It is permanent. No…

Black Kyanite4.5-7 Mohs · silicate · root, throatAfter certain people leave, you go around opening windows. Black kyanite gets sold for exactly that feeling. It grows in splayed blades…
Black Obsidian5-6 Mohs · volcanic glass · rootObsidian never got to be a crystal. Lava met air and cooled so fast the atoms stopped where they stood. What you hold is glass, made in…
Black Onyx6.5-7 Mohs · chalcedony · rootSomebody soaked this in sugar water for weeks. Then they cooked it in acid until the sugar turned to carbon inside the pores. That is…
Black Tourmaline7-7.5 Mohs · silicate · rootIt sits by the door, or you meant to put it there. Black, heavy, fine ridges running the length of it. Squeeze it or warm it and it…

The name…- Blue Aventurine6.5 to 7 Mohs · quartzite · throat, third-eyeBlue aventurine is a rock, not a crystal. That is the right place to start, because almost everything written about it starts somewhere…

Blue Kyanite4.5-7 Mohs · silicate · throat, third-eyeKyanite needs burial to exist. Clay rich rock gets pushed down and squeezed until the aluminium in it grows into blue blades. It came…
Blue Lace Agate6.5-7 Mohs · chalcedony · throatThe message is typed. You have read it four times and it is still sitting there. Blue lace agate built up in a lava cavity the same way…
Botswana Agate6.5-7 Mohs · chalcedony · crown, sacralBotswana agate built itself inside bubbles in old lava. Water came in, left a layer, dried, came back. Every grey and pink line is one…

Diopside belongs to the dense rock under the crust, and it stays there. The…
Chrysocolla2.5-7 Mohs · silicate · throat, heartRain got into a copper deposit and worked on it for ages. It broke the ore apart and left this blue-green crust in the cracks. It is the…
Chrysoprase6-7 Mohs · chalcedony · heartChrysoprase lives through almost anything except a sunny sill. Strong light pulls the apple green out of it, and it does not come back…

Crazy Lace Agate6.5-7 Mohs · chalcedony · solar-plexus, sacralHold it up and follow one band with a fingernail. It doubles back, folds over itself and starts again. That is because the rock cracked…
Dalmatian Stone6-7 Mohs · rock (aggregate) · root, sacralThose black spots are not tourmaline. The trade has said so for forty years and the trade is wrong. They are arfvedsonite, a softer dark…

Fire Agate6.5-7 Mohs · chalcedony · root, sacralTilt it under a lamp. Red and gold slide across the domes, then vanish when you hold still. That fire is not pigment. It is films of…
Fluorite4 Mohs · halide · third-eye, throat, heartFluorite survives almost nothing. A steel knife cuts it. One knock splits it clean along a flat plane, and long sun pulls the purple…
Galena2.5-2.75 Mohs · sulphide · rootIt is lead. The same lead that ran through Roman pipes and the same lead they took back out of petrol. Galena is soft, so it sheds fine…
Garnet6.5-7.5 Mohs · silicate · root, sacralGarnet grew inside rock that was being crushed. Heat and pressure squeezed the root of a mountain, and the garnet crystallised in the…- Golden Healer Quartz7 Mohs · quartz · solar-plexus, crownQuartz grows out of hot silica-rich water working through cracks in rock. Where that water is carrying iron as well, the iron comes out…

Hematite5.5-6.5 Mohs · oxide · rootIt looks like machined steel. It is rust. Iron and oxygen joined in an old sea and settled in layers on the floor. Burial pressed those…
Herkimer Diamond7 Mohs · quartz · third-eye, crownHold one up to a window. The faces throw the light straight back, and nobody cut them. They grew that way. Water full of silica crept…
Howlite3.5 Mohs · silicate · crown, third-eyeSomeone dyed it blue and sold it as turquoise. That is not gossip. It is the trade's default move. Howlite formed in old salt flats…
Iolite7-7.5 Mohs · silicate · third-eye, throatOld seabed mud got buried under a mountain and cooked until it came out as a different mineral. Turn it under one lamp. Violet blue from…

Kunzite6.5-7 Mohs · silicate · heartLight takes the colour out of it. Leave kunzite on a bright sill and the pink drains away, quite fast, and it never comes back. It grew…
Labradorite6-6.5 Mohs · feldspar · third-eye, throat, crownGrey and dull, like something off a driveway. Then you tilt it under a lamp and a sheet of blue switches on inside it. That flash is…
Lapis Lazuli5-6 Mohs · rock (aggregate) · third-eye, throatLimestone got cooked where hot magma pushed into it, and parts of it came out deep blue. One valley in Afghanistan has been mined for it…
Larimar4.5-5 Mohs · silicate · throat, heartSunlight takes the blue out of it, slowly and for good. Salt and long soaking dull it too. It filled gas bubbles in volcanic rock in one…
Leopardskin Jasper6.5-7 Mohs · rock (aggregate) · root, sacralThe name lies twice. It is not jasper, and those are not animal markings. It is old lava that cooled with crystals growing outward from…
Lepidolite2.5-3 Mohs · silicate · heart, third-eye, crownSomebody told you this one holds lithium. It does. The lithium is locked into the rock and it stays there. It cannot reach your blood…
Magnesite3.5-4.5 Mohs · carbonate · crown, heartSomebody dyed this. Most of the cheap turquoise in a mall case is plain white magnesite that was soaked in blue until it took. Undyed it…
Magnetite5-6 Mohs · oxide · rootHold it near a paperclip and the paperclip moves. That is not a trick. This rock is actually magnetic. It crystallized out of cooling…
Mahogany Obsidian5-6 Mohs · volcanic glass · root, sacralThis was lava moving too fast to become a crystal. It cooled into glass instead, and the red-brown clouds are iron that froze the second…
Malachite3.5-4 Mohs · carbonate · heart, solar-plexusMalachite is rust. Copper ore sat in wet ground and the water rebuilt it into a green carbonate, band by band. So it is a copper salt…

It sank into mud and the…- Pearl2.5 to 3 Mohs · organic · heart, sacralA pearl starts as a problem. Something works its way inside a mollusc and cannot be pushed back out, so the animal covers it.

Picture Jasper6.5-7 Mohs · chalcedony · root, third-eyeThose are not hills. They are layers of volcanic ash and fine mud that settled in still water, one on top of the next. Silica soaked…

Rainbow Obsidian5-6 Mohs · volcanic glass · root, third-eyeIt is glass. The lava cooled too fast for crystals to form, so nothing inside got to finish growing. Almost nothing. Tiny rods of…
Red Jasper6.5-7 Mohs · chalcedony · rootRed jasper is quartz too fine to see, stained through with iron oxide. Rust, basically. The same red as old brick and old blood.
