Gemmological Characters of Malipo Emerald from Yunnan Province

摘要: 云南麻栗坡祖母绿主要有伟晶岩脉型和云英岩脉型两种矿化类型。通过野外矿床地质勘测,配合现代测试分析技术,对麻栗坡祖母绿的矿床地质特征、宝石学特征、谱学特征及呈色机理予以初步探讨,证实麻栗坡祖母绿由Cr³⁺和V³⁺杂质离子致色,属贫Cr和Fe、富V的祖母绿类型。

Abstract: Malipo emerald deposit in Yunnan Province has two types of pegmatite vein and greisen vein. Through investigation in field and by means of the advanced modern testing method, the geological and gemmological characters of Malipo emerald are studied systematically. It is verified that the colour of Malipo emerald is caused by impurity ion of Cr³⁺ and V³⁺, and Malipo emerald belongs to the type which is poor in iron and chrome and rich in vanadium.
