|Most jade on the market is composed of nephrite; jadeite is very rare and in its emerald-green, translucent form is called Imperial Jade.||Jade is the gem name for mineral aggregates composed of either or both of two minerals, Jadeite and Nephrite. Jadeite is a sodium-rich aluminous pyroxene; nephrite is a fine-grained, calcium-rich, magnesium, iron, aluminous amphibole.|
All jade is composed of fine-grained, highly intergrown, interlocking crystals of one or both of these minerals. Though neither mineral is very hard (6-7), jade is one of the toughest gem minerals known.
