Labradorite fascinates by its magnificent play of colors, often in shades of blue-green, called labradorescence, and its metallic luster. Worn as jewelry, labradorite will be enhanced by the light. The American Indians called it "stone of fire" for this reason. Its main deposits are in Canada, on the Labrador Peninsula where it was discovered, but also in the United States, Madagascar, Mexico, Russia, and Finland for spectrolite (a variety of labradorite with all the colors of the rainbow in its reflections).
