Stones of Gemini

12 stones.

Agate Banded chalcedony, translucent to opaque, in grey, white, brown, red and blue layers; a cut slice may show the bands as rings or as a landscape. Agate is the tradition's stone of steadiness. Pliny takes the name from the river Achates in Sicily and reports that it was carried against scorpion and snake bite, and that athletes wore it to keep their nerve. Its bands are the point: the tradition reads a stone that grew in patient layers as an argument for doing the same. Hold the agate and find one band with your thumbnail. Name one thing you will not be moved on today. Put it in your pocket.
Apatite Transparent to translucent, most often a strong sea-blue or blue-green, also yellow, violet and colourless. Bright, glassy, and usually small. Apatite was named from the Greek for deceit, because it was forever being mistaken for other stones: beryl, tourmaline, peridot. The tradition turned the joke round and made it a stone of accurate seeing, a reminder that appetite and appearance both mislead, and that the honest question is what a thing actually is. Hold the apatite and name one thing you have been pretending about. Say the true version aloud. Then get back to work.
Celestite Pale sky blue, sometimes colourless or faintly straw yellow; transparent tabular crystals with a glassy shine, usually standing in a geode Celestite was named in 1799 for its colour, from the Latin caelestis, of the sky. It has almost no old lore, because the fine crystals come from geodes opened only in the last two centuries. What tradition it has is about stillness. It is a strontium mineral, pale and soft and easily ruined, and the practice built around it treats it the same way, kept in one quiet place. Put it where you can see it from your pillow. Before sleep, look at it and say the one thing you are going to stop thinking about tonight.
Chalcedony Translucent and waxy: milk white, pale grey or soft blue-grey, sometimes faintly banded. The look is half-lit rather than glassy. Chalcedony is quartz grown too fine to see, which gives it a waxy, half-lit look. It is the parent of agate, carnelian and onyx, but the pale grey-blue kind is its own stone. Roman seal-cutters favoured it because it takes a crisp intaglio and does not stick to warm wax. The lapidaries give it to speech, and to people who must say the same thing patiently many times over. Hold the chalcedony while you say, in a level voice, the thing you have already said five times, a sixth time.
Chrysocolla Opaque blue-green to sky-blue, often mottled or veined with black, brown and rust-coloured host rock; chalky where it is soft, glassy where quartz has hardened it. Chrysocolla means gold-glue. Pliny knew it as the green copper substance goldsmiths used to solder gold, and the lapidaries kept the name long after the trade changed. Tradition made it a stone of the throat, for the thing that is true, has waited years, and still has to be said out loud without shouting. Hold the chrysocolla and say the sentence you have been avoiding, quietly, to the empty room. Then wash your hands and say it to the person.
Citrine Transparent pale lemon through golden to a smoky madeira brown; most stones on sale are heat-treated amethyst and carry a faint reddish cast. Citrine is the tradition's stone of the open hand. It belongs to the Sun and, in later folk practice, to trade: dealers called it the merchant's stone and kept it in the till rather than wearing it. The lapidary line groups it with the yellow stones held to lift a heavy mood and steady anyone who has to ask other people for money. Put a citrine where you keep your money. Handle it once, name aloud one thing you intend to earn, and leave it there.
Emerald Transparent to translucent deep green, almost always with visible internal fractures and inclusions; the trade calls that internal world the jardin, the garden. Pliny holds that no colour is more pleasing to the eye than the emerald's, and reports that gem-cutters rested their sight on one after fine work. From that comes its whole tradition: the stone of the long look and the patient love. Lapidaries gave it to lovers as a truth-teller, and said that it clouded when a vow was broken. Look at the emerald until your eyes rest. Then look up, name the promise you are still keeping, and go and keep it today.
Fluorite Transparent to translucent, in purple, green, blue, yellow and colourless, often several of those banded within one crystal. Glassy, and frequently found as clean cubes. Fluorite takes its name from the Latin fluere, to flow: smelters added it to ore to make the metal run clean. The tradition reads that literally, and gives fluorite to a mind clogged with too many half-thoughts. Agricola named the fluores in 1546, and the murrhine cups Pliny prized are widely thought to have been carved from it. Set the fluorite on the page you are avoiding. Look at it, name the first small step out loud, and start with that.
Howlite Opaque chalk white to grey-white, threaded with fine grey or black veins like a web; nodular and cauliflower-shaped in the rough Howlite came out of a Nova Scotian gypsum quarry and was described in 1868 by Henry How, a chemist. There is no ancient lore behind it and this entry will not invent any. Its tradition is modern and domestic: it is the stone people keep for a mind that will not stop working at night. The veining is why it is dyed so often, since it mimics turquoise. When your thoughts will not stop, hold it and trace one grey vein with a fingertip, slowly, end to end. Then trace another. Stop when you lose interest.
Kyanite Translucent to transparent blades of blue, paler at the edges and deeper along the central streaks; also grey, green, orange and near-black. It grows in flat, splintery fans. Kyanite's old name is disthene, two strengths, for the plain fact that it is soft along its length and hard across it. The lapidary tradition likes a stone that admits to being two things at once, and gives kyanite to people who must hold a difficult position and stay flexible about how they hold it. Lay the kyanite blade flat on your palm. Name the position you are keeping and the thing you will bend on. Both, out loud.
Pearl Opaque white, cream, rose, gold, grey or black, with a soft inner glow called orient that comes from the layering of the nacre rather than from any pigment. A pearl is not a stone. It is nacre, laid down in fine layers by a living mollusc around something that irritated it, and that is the whole of its meaning in the tradition: the grain of sand answered with patience. Pliny puts pearls in his book on sea creatures rather than his book on gems, and tells there how Cleopatra dissolved one in vinegar to win a wager. Put on the pearl and name, silently, the thing that hurt and the thing you made of it afterwards. Wear it for the day.
Sodalite Opaque deep royal blue, marbled with white calcite veins, with occasional grey or violet patches. Sodalite came out of Greenland in 1811 and has no ancient lapidary behind it, so what it carries is recent and honest: a stone for people who think faster than they can speak. Practice gives it to teachers, witnesses and anyone who has to hold a line of argument steady while being interrupted. Before you speak, hold the sodalite and put what you mean into one sentence. Say that sentence. Then stop talking.
