我国罕见的有色宝石矿物——透视石

Dioptase A Rare Colored Gem

本文报导了作者对新近在我国发现的透视石所做的测定结果．在实测过程中，使用了显微硬度计、宝石显微镜、偏光显微镜、平面光删光谱仪、激光光谱仪、Ｘ射线自动衍射仪以及红外光谱仪等仪器．所得的结果补充了前人工作的不足．

This paper is about the determination of the dioptase which has been found in our country recently. In the course of our research, we used several kinds of instrument, such as microscopic hardnessmeter, Gemmological microscope, polarizing microscope, plane grating spectrograph PGS laser microprobe spectrogroph, X ray automatic diffractometer, and so on. The result is of good value. At the end of this report a brief comment about the value of the dioptase at gemmology is given.
