Tremolite Jade

This page is currently not sponsored. Click here to sponsor this page.
A variety of Nephrite

A generic term, referring to all varieties of nephrite which consist mainly of tremolite. While all white jades are tremolite jades, not all tremolite jades are white. Hetian Jade, Manasi Jade and Meiling Jade, which are typical representatives of tremolite jades, come in a variety of colours that are caused by inclusions of impurities. Hetian Jade can be white, yellow, bluish or black, and Manasi Jade is typically pale green, but they all mainly consist of tremolite with only traces of actinolite present.

Varieties of Tremolite JadeHide

Hetian JadeOne of the classic Chinese jades. It consists almost entirely of tremolite, but may contain up to 5 wt.-% of impurities such as diopside, epidote, clinozoisite, olivine, dolomite, quartz, magnetite, pyrite, apatite, limonite and carbonaceous matter, which...
Manasi JadeA green jade which consists mainly of tremolite with only minor actinolite. The green colour is caused by microscopic inclusions of green silicates, mainly chlorite and serpentine group minerals, and it frequently also contains diopside, grossular and chr...
Meiling JadeA typical tremolite jade, which comes in a variety of colours ranging from white to grey. The white colour varieties are the most valuable ones.
White JadeTremolite jades with a low content of impurities are termed white jades. They typically are white or nearly so and generally are the most valuable jades.
