Jade

Jade (jād) , noun

[French, from Sp. jade, from piedra de ijada stone of the side, from ijada flank, side, pain in the side, the stone being so named because it was supposed to cure this pain. Sp. ijada is derived from Latin ilia flanks. Compare Iliac.]

1.
(Mineralogy) A stone, commonly of a pale to dark green color but sometimes whitish. It is very hard and compact, capable of fine polish, and is used for ornamental purposes and for implements, esp. in Eastern countries and among many early peoples.

The general term jade includes nephrite, a compact variety of tremolite with a specific gravity of 3, and also the mineral jadeite, a silicate of alumina and soda, with a specific gravity of 3.3. The latter is the more highly prized and includes the feitsui of the Chinese. The name has also been given to other tough green minerals capable of similar use.
