Labradorite is the stone people buy twice. The first time, they buy it from a photo showing a strong blue flash. The second time, they buy it because the first bracelet arrived looking grey — and they want to understand why before spending again.
The answer is in how the stone is cut. Labradorite's colour is not pigment; it is light interference from microscopic layers inside the feldspar. Those layers sit on one plane, so the flash only appears when the light hits that plane at roughly the right angle. A bead cut with the plane facing sideways will look like plain grey stone from the front and blaze blue from the side.
What labradorite is, in mineral terms
Plagioclase feldspar, in the range between albite and anorthite. The optical effect is called labradorescence, and it is produced by repeated twinning — thin alternating layers that split and recombine light. Depending on the layer spacing, the flash can be blue, green, gold, or a mixed "spectrolite" range from Finland.
Hardness is 6 to 6.5 on the Mohs scale, with two cleavage directions, so it behaves much like moonstone: it cracks rather than dents, and thin edges are vulnerable. Body colour is dark grey to near-black, which is why a strong flash reads as dramatic against it.
How to tell real labradorite from copies
The flash should move and switch off. Tilt the bead. Real labradorite either shows a narrow band that sweeps across the face or turns grey. Glass imitations tend to glow from every angle with a canned, slightly metallic sheen.
Look for the grey body. Natural material has visible dark feldspar between the flashing zones, often with fine cracks or black inclusions. Copies are uniform.
Check the flash boundary. On real stone the blue zone has an irregular edge that follows the internal structure. On coated or glass beads the boundary is crisp and identical on every bead.
Weigh it. Feldspar is dense for its size. Glass beads of the same diameter feel noticeably lighter in the hand.
What to look for when you buy
Flash coverage per bead. A strand where every bead flashes strongly is expensive and usually hand-selected. Expect variation: most bracelets have a few strong beads, several partial, and a couple that read as plain grey. That is honest material.
Flash colour. Blue is the most common and the most consistent across beads. Gold and green flashes are normal too. Purple and full-spectrum flashes come from specific deposits and cost more.
Bead size. Larger beads show more flash area, so 8mm and 10mm read better than 6mm. Our size guide explains fit for each.
Surface quality. Labradorite is often sold with a slightly matte or "raw" polish. That is a style choice, but check the drill holes for chips — feldspar chips at the rim and cuts elastic.
Care and wear
Warm water, mild soap, soft cloth, dry immediately. No ultrasonic, no steam, no sudden temperature change. Labradorite is sensitive to cleavage cracks, and a filled crack can propagate with vibration.
Because the flash depends on the bead's orientation, restringing can change how the bracelet looks — beads rotate on the cord over time, which is why a bracelet that flashed blue on day one may look flatter a month later. That is not the stone fading; it is the beads turning. Full method in the crystal care guide.
What the meaning claims can and cannot support
Labradorite is marketed with a heavy vocabulary — transformation, intuition, psychic protection, "the stone of magic". The name association comes from Labrador, Canada, where it was first documented, and the folklore grew afterwards, mostly in the twentieth century.
There is no clinical evidence that the stone does any of those things. What is true is that the optical effect is genuinely unusual, it is the reason the stone is priced where it is, and it gives you a concrete thing to check before buying. Our buying guide covers the rest of the checks.
Frequently asked questions
Is labradorite natural? Yes, when it is feldspar with labradorescence. Glass with a printed or metallic flash is the common substitute and looks uniform from every angle.
Why does my labradorite look grey? Because the flash is directional. If the bead's internal layers face away from the light, you see the grey feldspar body. Rotating the bracelet usually brings the blue back.
What is labradorite's hardness? 6 to 6.5 on the Mohs scale, with two cleavage directions. It chips on impact and should not be cleaned ultrasonically.
Where does labradorite come from? Labrador in Canada, Finland for spectrolite, and Madagascar, which supplies much of the commercial bead material. Vincryst lists origin per product page.
Is labradorite the same as rainbow moonstone? No. Rainbow moonstone is white labradorite sold under a different name. True moonstone is a different feldspar intergrowth with a softer, floating sheen.
