What is Jade?

Jade is an ornamental stone. The term jade is applied to two different rocks that are made up of different silicate minerals. Nephrite jade consists of the calcium- and magnesium-rich amphibole mineral actinolite. The rock called jadeitite consists almost entirely of jadeite, a sodium- and aluminum-rich pyroxene. The trade name Jadite is sometimes applied to translucent/opaque green glass.

The English word ‘jade’ is derived from the Spanish term piedra de ijada or ‘loin stone’, from its reputed efficacy in curing ailments of the loins and kidneys. ‘Nephrite’ is derived from lapis nephriticus, the Latin version of the Spanish piedra de ijada.

A jade necklace and other jewelry are among the most popular examples of accessories out there.
