What was traditionally called jade
is in fact two separate and distinct minerals: jadeite and nephrite. The term 'jade' can also be loosely applied to materials that contain jadeite or nephrite, such as maw-sit-sit and other materials. Jade has been treasured for centuries by cultures around the world, including the Mesoamericans and the Chinese, who consider it to be an auspicious gem. Choose jade gems from various shapes, sizes and colors, including green jade and lavender jadeite.
