| Name: | From "piedra de ijada" stone of the flank, as it was thought to cure kidney pains. | ||
|---|---|---|---|
A greenish black to creamy white ornamental stone or gemstone, highly valued in China and Korea. Translucent emerald-green jadeite-jade is the most prized variety.Rarely also blue, lavender-mauve and pink in colour, depending on mineralogy and impurity elements.
Many different rocks and minerals have been marketed as jade, especially nephrite and serpentine, but also green quartz, vesuvianite (californite), etc. Gemmologists, however, usually restrict the name to just jadeite and nephrite, both characteristically forming very tough, fine grained rocks. Nephrite is much more common than jadeite, and is a tremolite and/or actinolite-rich rock.
