Labradorite was named after the Canadian peninsula "Labrador", where it was first discovered. Labradorite has a dark, smoke grey base, but displays irridescent colors when moved in the light in an effect called "schiller" or "labradorescence". These rainbow of colors can include gold, green, yellow, and orange. Labradorite is said to help arthritis, rheumatism and other bone and joint problems. It is said to have a calming effect which helps to clarify ones views. Rox Jewelry carries beautiful labradorite jewelry, including pendants, bracelets, earrings, rings and necklaces.
