Labradorite 1x2mm Square Rondelle - 15-16 Inch Shape_Star Cut These form as a crissLabradorite 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.
