Labradorite is a member of the Feldspar family and is treasured for its remarkable play of color, known as labradorescence. The stone, usually a smoky quartz-looking gray-green, dark gray, black or grayish-white, is composed in aggregate layers that refract light as iridescent flashes of peacock blue, gold, or pale green. Labradorite is named after the peninsula of Labrador in Canada, where it was first discovered in 1770.
According to an Inuit legend, the Northern Lights are captured in the minerals on the coast of Labrador.
The most impressive pieces are mined in Finland and Madagascar.
