Jade is the general name given to two gemstones, jadeite and nephrite. Despite that they may be similar in appearance, the two minerals have little else in common. The term "jade" does not refer to a specific mineral but is rather a historical term used for both jadeite and nephrite when sophisticated separation techniques were not available.
