Nephrite is a variety of the calcium and magnesium and iron-rich amphibole mineral tremolite or actinolite.
It is one of two different mineral species called jade. The other mineral species known as jade is jadeite. While nephrite jade possesses mainly grays and greens (and occasionally yellows, browns or whites), jadeite, which is rarer, can also contain blacks, reds, pinks and violets.
Nephrite jade is an ornamental stone, used in carvings, beads, or cabochon cut gemstones.
Western Canada is the principal source of modern lapidary nephrite. (And our source at BigGreenBuddha.com) 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 southeast Asia.
