Diopside

透辉石属辉石族。单斜晶系,晶体呈短柱状,透明至不透明,玻璃光泽。颜色呈浅绿至深绿,随含铁量增加,颜色会加深,变成褐色,甚至黑色。

透辉石的典型产状是接触交代变质成因,是一种常见的矿物,但是达到宝石级的晶体不多。结晶良好的晶体主要产自大理岩和金伯利岩中。但绝大多数提供市场商业流通的宝石级晶体,主要来自缅甸和斯里兰卡的砾岩中。

·星光透辉石中相交的针状内含物

一种含铬元素的铬透辉石,色泽鲜艳翠绿,具有璀璨的光泽度,颜色酷似祖母绿,市场认可度颇高。铬透辉石大都出自俄罗斯、芬兰,有“西伯利亚祖母绿”之称。但大颗粒成品宝石不多见,大都在1~4克拉。另有一种产自印度的透辉石,含有大量相交的针管状内含物,可形成四射星光,称星光透辉石,其颜色大都呈深黑绿色,很少有绿色。

When colored by chromium, it is bright green and is known as chrome diopside. Diopside can exhibit chatoyancy. Star diopside is primarily found in India and most often appears as a blackish-green cabochon with four rays.
