COMPARATIVE STUDY ON THE COLOR OF NATURAL EMERALD,SYNTHETIC EMERALD AND GREEN BERYL

摘要: 天然祖母绿、合成祖母绿、绿色绿柱石在成分和外观上有一定的相似性。为了探讨这三种宝石在颜色和成分上的差异，对其进行了对比研究。电子探针分析表明，三者颜色与微量元素铬、钒有关．MPV-3显微光度计下对颜色定量测量的结果表明，三者的视觉透过车、兴奋纯度、主波长和可见光吸收光谱等方面的差别较大。这些差别的存在导致了宝石在颜色的色调、饱和度和明亮程度上的不同。

Abstract: Natural emerald，synthetic emerald and green beryl sometimes have similar appearance. Author analyses them by electron microscopy and visible light spectrometer in order to determine the difference among them in chemical com position and color indexes. The result shows that their colors are related to the concentration of trace elements, Cr and V; the color index of each one is characteristic.
