摘要: 采用宝石显微镜、偏光显微镜、电子探针、X射线粉末衍射仪和傅里叶变换红外光谱仪等测试方法对近期在北京珠宝市场上大量出现的一种仿苏纪石材料样品进行了常规宝石学、矿物学、谱学特征研究。结果表明,该仿苏纪石材料是以透闪石为主要矿物、石英为次要矿物的染色玉石;其与天然苏纪石的主要鉴别特征为:该仿苏纪石材料的密度较大,表面较粗糙以及特征的红外光谱。

Abstract: Recently,some imitated sugilite products appear in the Beijing jewelry market.The gemmological,mineralogical and spectral characteristics of the imitated sugilite samples are studied by using the gem microscope,polarizing microscope,electron microprobe(EMP),X-ray powder differaction(XRD) and Fourier transform infrared spectrometer(FTIR).The results show that the imitated sugilite samples are mainly composed of tremolite and quatz with dyeing.The identification characteristics between the imitated sugilite and natural sugilite are that the imitated sugilite is of higher density,rougher surface and characteristic infrared spectra.
