From GIA, Carlsbad, Calif. - For most people, jade evokes an image of a brilliant green gemstone. Surprising to many, it also occurs as luminous examples of many other colors including white, orange, and lavender. Because of its beauty and durability, jade has been treasured around the world for centuries.
