Jadeite is a pyroxene mineral with composition Na Al Si 2 O 6. It is hard (Mohs hardness of about 6.5 to 7.0), very tough, and dense, with a specific gravity of about 3.4. It is found in a wide range of colors, but is most often found in shades of green or white. Jadeite is formed only in the subduction zones of continental margins, where rock ...

Jadeitite consists almost entirely of the pyroxene mineral jadeite and is typically mined as a source of the ornamental rock or gemstone, jade.
Colloquially 'jade' objects in Mesoamerica are composed of jadeite, but may also refer to other similar-looking, relatively hard greenstones such as albitite, omphacite, chrysoprase, and quartzite. [3] Variation in color is largely due to variation in trace element composition. In other words, the types of trace elements and their quantities ...
The jade trade in Myanmar consists of the mining, distribution, and manufacture of jadeite —a variety of jade —in the nation of Myanmar (Burma). The jadeite deposits found in Myanmar's northern regions are the source of the highest quality jadeite in the world, noted by sources in China going as far back as the 10th century.
