Labradorite is a relative latecomer to the crystal community, having not been discovered until the 19th century. It is named after the region in Canada where it was first found, although large deposits have since been discovered in Norway. This normally drab colored rock is prized for its iridescence. When the light strikes a piece of labradorite just right, it will flash a brilliant array of blues, greens, oranges, and yellows.
