Jade is an ornamental stone. The term jade is applied to two different rocks that are made up of different silicate minerals,|
namely the rock Nephrite (jade) and the rock Jadeitite.
Burma (Myanmar) and Guatemala are the principal sources of modern gem jadeitite, and Canada of modern lapidary nephrite.
Nephrite jade was used mostly in pre-1800 China as well as in New Zealand, the Pacific Coast and Atlantic Coasts of North America,
Neolithic Europe, and south-east Asia. In addition to Mesoamerica, jadeitite was used by Neolithic Japanese and European cultures.
