摘　　要：通过对实验室收到的三件浅紫色样品进行常规宝石学测试,记录下它们的颜色、透明度、光泽、密度和折射率等信息,然后在正交偏光镜下观察其结构特点,确定这三件样品分别为集合体、单晶体与集合体混合体和单晶体。最后使用大型仪器电子探针和红外光谱仪对这些样品进行了测试分析,确定三者的主要成分均为硬玉,因此这三件集合体硬玉、单晶体与集合体混合体硬玉和单晶体硬玉的命名分别为翡翠、硬玉和硬玉。Three light purple samples received by the laboratorywere subjected to fundamental gemological tests.Their color,transparency,luster,specific gravity,refractive index,and other information were recorded,and then their structural characteristics were observed under the orthogonal polarizing microscope,and the three samples were identified to be the aggregate,the monocrystal and aggregate mixture,and the monocrystal.Finally,the samples were tested and analyzed by large-scale EPMA and infrared spectrometer,and the main components of the three samples were tested to be jadeite.Therefore,these three pieces of aggregate jadeite,single crystal and aggregate mixture jadeite,and single crystal Jadeite were respectively named asFeicui,jadeite,and jadeite.
