摘　　要：现代技术对钻石业的影响在不断的扩大,通过改善钻石的颜色并由此提高其价格的方法变得尤为先进,如何有效的区分天然与优化处理的钻石一直是宝石学的研究热点,对鉴别彩色钻石而言其任务更加艰巨。笔者运用美国海洋光学公司生产的微型光纤光谱仪(USB4000),对来自中国、俄罗斯、韩国等地的17颗钻石样品进行了谱学分析,结果表明该测试方法能高效、快速、低成本地区分天然、高温高压处理、辐照处理的钻石,且同种类型不同颜色的钻石样品之间又存在着较明显的差异。因此,该方法为钻石的检测提供了可行性依据,具有非常广阔的应有前景。Modern technology is increasing its impact on the diamond sector.Methods for changing the color and consequently the value of diamonds are becoming more and more advanced.So how to identify the nature and the treated diamond is always being the focus of gemology.The authors use USB4000,which is manufactured by American Ocean Optics company,to test 17 diamond samples which come from China,Russia,and Korean etc..The results show that USB4000 can distinguish nature,high temperature high pressure treatment,and irradiated enhanced diamonds efficiently and quickly.And the same kind of diamond with the different colors exist remarkable difference.So,it provides a method to identify the diamonds and will have a wide application prospect.
