Labradorite is a member of the Feldspar family and is treasured for its remarkable play of color, known as labradorescence. The stone, usually gray-green, dark gray, black, or grayish-white, is composed of aggregate layers that refract light as iridescent flashes of peacock blue, gold, pale green, or coppery red. The predominant blue varies within the light, displaying hues from deepest blue to various shades of pale, almost blue-green.
