摘要
钻石原石因形状、表面纹理发育而特征多变,尤其是透明度不佳而给测试带来不少困难。钻石作为一种珍贵宝石,对其的各种处理技术越来越复杂而难以鉴别,尤其是高温高压处理技术,时至今日仍是宝石学中最困难的课题。本文以一颗馆藏典型的褐色钻石原石为例,采用宝石显微镜、UV-Vis-NIR光谱仪、傅立叶变换红外光谱仪、光致发光仪和拉曼光谱仪探讨其检测方法及褐色钻石典型的鉴定特征。
Because of shape and the variable characteristics of surface texture,especially poor transparency,Rough diamond is very difficulties to test and identification.Diamond as a precious gemstone,its various treatment techniques are more and more complex and difficult to identify,especially the high temperature and high pressure treatment technology,is still the most difficult subject in gemology today.In this paper,a typical brown rough diamond collected by the Guangdong Provincial geological science Education Center is taken as an example.Gem microscope,UV-Vis-NIR spectrometer,Fourier transform infrared spectrometer,photoluminescence spectrometer and Raman spectrometer were used to investigate the detection methods and typical identification characteristics of brown diamonds.
