摘　　要：对一件外观酷似翡翠的雕刻样品进行常规宝石学特征测试,结合了红外吸收光谱仪、紫外可见光谱仪、X荧光能谱仪分析,结果表明,该样品折射率为1.57,相对密度为2.68,红外吸收光谱测试为绿柱石,紫外可见光谱分析未发现由Cr引起的684nm吸收峰,X荧光光谱分析含Fe和V元素,通过分析该样品为绿色绿柱石,Fe和V是其呈现绿色的原因。因不含Cr元素,故不能定名为祖母绿。A engraving sample with the appearance similar to jadeite was tested on its gemological characteristics with the standard gemological methods.It was analyzed by infrared absorption spectrometer,ultraviolet visible spectrometer and X-ray fluorescence spectrometer.The results showed that the refractive index of the sample was 1.57,the relative density was 2.68,the infrared absorption spectrum was beryl.The absorption peak of 684nm caused by CR was not found in the ultraviolet visible spectrum,and the X-ray fluorescence spectrum indicated it contained Fe and V elements.Through the analysis,the sample was defined as green beryl,and Fe and V were the reasons for its green.But it was not suggested to be named as emerald for it did not contain Cr element.
