Clear quartz
Quartz, silicon dioxide (SiO2), in its colorless form; sometimes called rock crystal.
A well-formed crystal is colorless to faintly milky, glassy, and often six-sided, with a pointed end and fine horizontal lines on the long faces. Tumbled chips lose that shape and keep the glassy look, sometimes with inner cracks, clouds, or tiny specks. Color alone is not an identification, and a lot of cheap clear material in shops is simply glass.
What it actually is
| Name used here | Clear quartz |
| Mineral or material | Quartz, silicon dioxide (SiO2), in its colorless form; sometimes called rock crystal. |
| Hardness | Mohs 7. |
| How it forms | Quartz grows from silica-bearing water in veins, cavities, and pegmatites, and the same mineral, once broken, makes up an enormous share of sand. A clear piece is quartz that picked up little iron or radiation damage to color it. |
Trade names and mix-ups
Rock crystal is the older honest name, and it still means colorless quartz. Herkimer diamond is quartz from one New York county, not diamond, and aura quartz is ordinary quartz coated in a lab with a thin metal film. Master healer and programmable stone are shop slogans, not species, and they tell you nothing about whether a piece is coated, glued, or glass.
Care
Hard enough for pockets and desks, but a knock on tile can still shatter it along a hidden crack, and a jump from cold to hot sun can split it. Rinse dust off with plain water and dry it at once; do not boil it, bake it, or park it in a bowl of salt. Metal-coated aura pieces should stay dry, or the film dulls and flakes. Wipe with a soft cloth rather than a scouring pad.
Provenance
Gift-shop quartz is usually mass-mined and mass-tumbled, often far from the counter that priced it, and the harm is the ordinary harm of industrial rock removal rather than a story a slogan can fix. Ask where it was cut if the seller knows, and do not pay a healing-tax for a mineral that is common.
Symbolism
- a pause before speaking
- plain language
- one revised sentence
- daylight honesty
Folklore, only where it exists
Greek krystallos means ice, and classical writers, Pliny among them, repeated the idea that rock crystal was ice frozen so hard it would never thaw: bad geology, and a long human habit of making weather into a stone. Colorless quartz was carved into beads, cups, and later lenses in more than one culture, and European lapidaries assigned it virtues as they did to most pale gems. None of that is the twentieth-century system in which clear quartz is a master healer you can program like a device. The Wilde Altar keeps the older mistake and the newer slogan in the same drawer: stories about a stone, not behavior of silica. You may still use its plainness as a cue to say the smaller true thing, including in a toast for two grooms, two brides, or any spouses an old form forgot to name.
Cautions
An original practice
The Margin Draft
- A piece of clear quartz
- A draft on paper
- A pencil
- A glass of drinking water kept off the page and off the stone
- 1Set the quartz on the first paragraph you are willing to read aloud in daylight.
- 2Read that paragraph once, then cross out any sentence that exists only to make you sound kinder or grander than you were when you wrote it.
- 3Move the stone to the next paragraph and repeat. A wedding toast counts, including one for two grooms or two brides; so does a note to a landlord or to yourself.
- 4Stop after three paragraphs even if the draft is longer, and leave the quartz on the last line you actually changed.
- 5Stand up, finish the glass that never touched the stone, and decide whether the note is ready. The stone does not get a vote.
Leave the extra sentence. Say the smaller true thing. Then send it, or do not.
Return the quartz to its ordinary dish. Either send the shorter version or put the draft where tomorrow-you will find it without a treasure hunt.
A practical action. Send the revised note, or write a time tomorrow when you will finish it, and keep the crystal out of any glass.
Substitutions
- A clear drinking glass turned upside down as a paperweight
- A plain white index card in place of the stone
Beginner questions
- Is clear quartz the same as glass? No. Glass is amorphous; quartz is crystalline. They can look alike once tumbled, so mold seams and a very low price are worth a second look.
- Can sunlight charge it into a medicine? No. Short ordinary light is fine, sudden heat can crack a stone, and no amount of sun turns a rock into a treatment.
- Does it need salt? No. Salt is not a cleanser here. Skip the soak, and wipe the piece with a cloth.
