jade,

common name for either of two minerals used as gems. The rarer variety of jade is jadeite, a sodium aluminum silicate, NaAl(SiO3)2, usually white or green in color; the green variety is the more valuable. The commoner and less costly variety of jade is nephrite, a calcium magnesium iron silicate of varying composition, white to dark green in color. Jade has been prized by the Chinese and Japanese, as well as by pre-Colombian Mesoamerican peoples, as the most precious of all gems. The Chinese in particular are known for the objets d'art they carve from it, and they traditionally associated it with the five cardinal virtues: charity, modesty, courage, justice, and wisdom; they also attributed healing powers to it. It was much used for implements by ancient peoples, especially in Mexico, Switzerland, France, Greece, Egypt, Asia Minor, and New Zealand. Jadeite is found in upper Myanmar, in Japan, and in Guatemala; nephrite in New Zealand, Turkistan, Siberia, China, Silesia, Wyoming, California, and British Columbia.
