|Jadeite is a pyroxene mineral with composition NaAlSi2O6. It is monoclinic and has a Mohs hardness of about 6.5 to 7.0 depending on the composition. |
The Latin version of the name, lapis nephriticus, is the origin of the term nephrite, another variety of jade. Jadeite is formed in metamorphic rocks under high pressure and relatively low temperature. In all well-documented occurrences, jadeitite appears to have formed from subduction zone fluids in association with serpentinite.
Jadeite from the Motagua Valley, Guatemala, was used by the Olmec and Maya, as well as the indigenous peoples of Costa Rica.
Typically, the most highly valued colors of jadeite are the most intensely green, translucent varieties, though traditionally white has been considered the most valuable of the jades by the Chinese.
