According to an Eskimo legend, the Northern Lights were once imprisoned in the rocks along the coast of Labrador. It is told that a wandering Eskimo warrior found them and was able to free most of the lights with a mighty blow of his spear. Some of the lights were still trapped within the stone, and thus we have today the beautiful mineral known as labradorite.
