摘　　要：本文通过扫描电镜(SEM)、X射线粉末衍射仪(XRD)、傅里叶红外光谱仪(FIR)及宝石学常规仪器对"永楚料"翡翠、缅甸翡翠及墨翠的宝石学性质进行分析对比.结果表明危地马拉"永楚料"翡翠、缅甸翡翠及墨翠在查尔斯滤色镜下、紫外荧光下表现一致."永楚料"翡翠的折射率约为1.65,稍低于缅甸翡翠和墨翠;密度约为3.36,稍高于缅甸翡翠和墨翠;"永楚料"翡翠的结构为变晶结构,主要组成矿物为绿辉石,含有少量透辉石,"永楚料"翡翠的红外光谱与绿辉石的标准红外光谱近于一致.The gemological properties of ＂Yongchuliao＂Jadeite,Burma Jadeite and Mocui jadeite were analyzed and compared by scanning electron microscopy（ SEM）,X-ray power diffraction（ XRD）,Fourier infrared spectrometer（ FIR） and gemological conventional instruments. The results showed that the ＂ yongchuliao＂ Jadeite of Guatemala,Burma Jadeite and Mocui jadeite are consistent under the Charles filter and ultraviolet fluorescence. The refractive index of＂yongchuliao＂jadeite is about 1. 65,slightly lower than that of Burma Jadeite and Mocui jadeite. The density of ＂yongchuliao＂Jadeite is about 3. 36,heavier than that of Burma Jadeite and Mocui jadeite. The structure of ＂yongchuliao＂Jadeite is the crystalloblastic structure,which mainly consists of omphacite with a small amount of diopside,The infrared spectrum of ＂yongchuliao＂Jadeite is basically the same as the standard infrared spectrum of omphacite.
