中国彩色钻石概要特点

彩色钻石是一种极端珍稀的矿产与宝石财富.本文较全面论述了中国已经发现的主要彩钻产地及矿体的简要地质特征,从原生矿和砂矿角度,分别论述了山东、辽宁、湖南、贵州等地的彩钻矿体地质特点,并总结了中国彩钻的主要特点:含量极低,晶体完整度不一,多含有包裹体,晶体蚀象发育,透明度高,以山东彩钻为代表的中国彩钻的颗粒度相对较大,可做高端宝石应用.本文还指出,中国彩钻的价值从根本上还没有得到发掘,市场价值从根本上尚未得到体现.

Characteristics of China's colored diamonds

Colored diamonds belong to a kind of extremely rare ore resources and gemstone wealth. This paper describes in detail the main producing areas of colored diamonds in China and the geological characteristics of the orebodies and, from the angles of primary deposit and placer, deals with geological characteristics of colored diamond orebodies in such provinces as Shandong, Liaoning, Hunan and Guizhou. According to the results achieved, China''s colored diamonds are characterized by extremely rare content, varying crystal completeness, existence of inclusions in most diamonds, well-developed crystal corrosion and high transparency. China''s colored diamonds represented by those from Shandong have relatively large grain sizes and hence can be applied as high-end gemstones. It is also pointed out that the value of China''s colored diamonds has not been fundamentally tapped, and their market value has not been fully manifested yet.
