Labradorite 11x40mm Faceted Marquise

Gray until it turns, then blue across the whole face.

Hold a strand up and turn it slowly. One bead goes flat gray, the next throws a sheet of blue across its whole face, and a third gives you a thin edge of gold before it closes again. Faceted labradorite does this bead by bead, so no two strands look alike. The body color runs gray to near black, which is why people reach for it: a neutral that lights up when the wrist moves.

The color play has a name of its own, labradorescence, borrowed from the stone that made it famous. What makes it happen is ordinary enough: light reflecting off thin twin layers inside a gray to black body. What tradition made of it is less ordinary. Because the flash appears and disappears as the bead turns, labradorite has long been called a stone of transformation, and that is how crystal tradition still describes it. The observation behind the belief is one any maker makes at the bench: the light sits inside the stone all the time, and the angle is what decides whether you can see it.
