Labradorite 3x6-6x9mm Faceted Irregular Drop - 8 Inch Stone Type_Blue Moonstone and it can be mottledLabradorite is remarkable for the way its aggregate layers refract light, creating iridescent flashes of blue, gold, pale green or copper red. This effect is known as labradorescence, taking its name from the stone. Labradorite is usually gray to green, dark gray, light gray or black. It was discovered in Labrador, Canada in 1770 and named for the area, though it is referenced as a highly revered stone in much older Inuit tribal legends.
