摘　　要：近期本实验室收到一粒蓝宝石仿制品,外观与蓝宝石极为相似,蓝色,透明。经常规宝石学特征测试并结合红外光谱仪、紫外可见光谱仪、X荧光光谱仪等大型仪器分析,结果表明该样品矿物名称为假蓝宝石,折射率为1.703~1.718,双折射率为0.015,相对密度为3.60,多色性强,红外吸收光谱特征吸收峰为988 cm^(-1)、822 cm^(-1)、725 cm^(-1)、606 cm^(-1)、548 cm^(-1)、498 cm^(-1)、428 cm^(-1),X射线荧光光谱测试含有Fe和Ga,过渡元素Fe应该是致色元素。Recently,our laboratory received a sapphire imitation,which looks very similar to sapphire,especially in blue color and transparent.After using standard gemological test,combined with infrared spectrometer,ultraviolet-visible spectrometer,x-ray fluorescence spectrometer and other instrument analysis,the results show that the sample is sapphirine,with the refractive index of 1.703-1.718,the birefractive index of 0.015,the relative density of 3.60,and strong pleochroism.The characteristic absorption peaks of the infrared absorption spectrum are 988cm^(-1),822cm^(-1),725cm^(-1),606cm^(-1),548cm^(-1),498cm^(-1),428cm^(-1).The x-ray fluorescence spectrum test contains Fe and Ga,the transition element Fe should be a color-causing element.
