摘要

关于作者，见文章末尾。《GEMS & GEMOLOGY》，Vol. 54, No. 4, pp. 428-429, http://dx.doi.org/10.5741/GEMS.54.4.428©2018美国宝石学研究所许多宝石级钻石不具有此类诊断特征，需要进行高级宝石学测试，以确定它们是开采、实验室生长还是经过处理的。例如，铬石榴石包裹体可以表明钻石形成于橄榄岩环境，而辉长石和蓝晶石包裹体则表明钻石形成于榴辉岩环境。对宝石学家来说，其他值得诊断的特征是所谓的“闪光效应”颜色，这种颜色装饰着铅玻璃填充的裂缝和锥形管，表明是激光钻孔。自1986年以来，宝石级合成钻石已经商业化;然而，最近我
