Labradorite
A plagioclase feldspar, a sodium-calcium aluminum silicate, known for labradorescence.
The body color is often dull gray, green-gray, or black until the stone is turned and a flash of blue, gold, or green moves across it in patches. The flash depends on the angle. A piece with no flash at all may still be the feldspar, but the flash is why anyone mined it for jewelry, and a painted rainbow will not move when you tilt the stone.
What it actually is
| Name used here | Labradorite |
| Mineral or material | A plagioclase feldspar, a sodium-calcium aluminum silicate, known for labradorescence. |
| Hardness | About Mohs 6 to 6.5. |
| How it forms | Labradorite crystallizes in mafic igneous rocks such as anorthosite and basalt, and the color play comes from light interfering in microscopic layered structures inside the feldspar. The layers grew in cooling rock; they are not a compressed aurora. |
Trade names and mix-ups
Spectrolite is a trade name for especially vivid labradorite from the Ylämaa region of Finland, not a separate species. Rainbow moonstone is usually pale labradorite mislabeled to borrow moonstone's reputation. Neither nickname changes the feldspar, and a coated gray bead with glitter glue is not labradorescence.
Care
It cleaves and chips, so rings and loose pockets full of keys are a gamble. Avoid ultrasonic cleaners, steam, salt soaks, and thermal shock. A lukewarm damp cloth and a full dry are enough; do not soak it. Long harsh sun is unnecessary and unkind to feldspar polishes. Dust, do not scrub.
Provenance
The European name dates to late eighteenth-century specimens from Labrador, but most commercial rough now is Madagascan, while Finnish spectrolite is a smaller trade, and Indigenous peoples of Labrador knew the stone long before a mineralogist named it. Their knowledge is not a product description: buy commercial stone, and do not strip a northern beach because a book called it free magic.
Symbolism
- the angle you choose
- a flash that moves
- privacy in a public room
- showing only what you mean to
Folklore, only where it exists
European science named labradorite in the late eighteenth century from Labrador finds; the spectacular Finnish material was branded spectrolite in the twentieth. There is no thick ancient magical literature under this name, because the name is young, and shops should not borrow Innu or Inuit teachings to fill the gap. What grew instead is a modern script about auras, shields, and a stone that changes your energy when the color flashes. The flash is optical interference. The Wilde Altar lets you use that angle-play as a metaphor you control: you decide what a room gets to see. That includes a dinner where you introduce a partner, boyfriend, girlfriend, husband, or wife, without a rehearsal of apology. It does not include a claim that the feldspar hides you from harm.
Cautions
An original practice
The Angle You Choose
- A piece of labradorite
- A lamp
- A notecard
- A pen
- 1In ordinary lamplight, tilt the stone until you find a flash, then tilt it until the flash leaves. Notice that you did that with your wrist.
- 2On the card, write two short lines: what you are willing to talk about tonight, and what you will decline with a sentence you have already chosen.
- 3If you are bringing a partner, plan the introduction in the words you both actually use. No one at the table is owed a glossary of your life.
- 4Set the stone on the card by the door while you dress or wash up. It does not go in a glass.
- 5Read the two lines once, put the card in a pocket or a bag, and leave the stone at home unless it is a polished piece you have already decided is sturdy enough for a pocket.
The color moves when I move. I show what I came to show. The rest is not a puzzle for the room.
Put the labradorite back in a cloth so it does not knock against metal overnight. The card can be recycled after you are home.
A practical action. Use the sentence you wrote if the moment arrives, and leave when you meant to leave.
Substitutions
- A CD or a piece of iridescent gift wrap, tilted under the lamp the same way
- A gray button with no flash, if the point is the card and not the optic
Beginner questions
- Is labradorite the same as moonstone? No. They are related feldspars with different optical effects. Rainbow moonstone is often labradorite under a borrowed name.
- Does the flash mean it is protecting my aura? No. The flash is light in microscopic layers. Any privacy you have tonight comes from your choices and from other people behaving.
- Can it go in a gem elixir? No. Do not drink water that held it, and do not expect a feldspar to treat anything.
