Jadeite is formed only in the subduction zones of continental margins, where rock undergoes metamorphism at high pressure but relatively low temperature. Jadeite is the principal mineral making up the most valuable form of jade, a precious stone particularly prized in China. Most gem-quality jadeite jade comes from northern Myanmar.

Jadeite is presumed one of the most precious materials of Pre-Columbian Costa Rica. It, along with other similar-looking greenstones (e.g. chalcedony, serpentine, and green jasper) were cherished and worked for years. Jadeite was used to decorate the body and was presumably a symbol of power.
The term also includes jade and jadeite, although these are perhaps more frequently identified by these latter terms. [2] The greenish hue of these rocks generally derives from the presence of minerals such as chlorite, hornblende, or epidote. [3] Greenstone minerals were presumably selected for their color rather than their chemical composition.
