Labradorite is a feldspar mineral. It has a labradorescence which is the meaning behind its name. The crystals are often found in thin and tabular shapes with colors ranging from purple to grey blue, green, yellow, and brown. The mineral has a pearly sheen and some specimens have a schiller effect. Linked to the glimmering gold and green lights of the Aurora Borealis, the Labradorite stone is as mystical as its iridescent changing colors suggest.
