和田仔料随着市场的追捧,其价格越来越高,仿制品层出不穷。借助宝石显微镜、偏光显微镜、X射线粉末衍射和红外光谱等测试手段,对武汉市徐东古玩珠宝市场上出现的一种仿黑皮仔料材料进行了宝石学、矿物学以及谱学特征鉴定。结果显示,该仿黑皮仔料材料由黑色霞石岩、白色软玉以及有机黑胶三部分拼合而成;其与黑皮仔料的主要鉴定特征在于：前者在横截面上有明显的拼合痕迹以及特征的红外光谱有机官能团区吸收峰。

The price of nephrite gravel is becoming higher and higher due to the growing market demand,and more and more imitations are produced.By means of gemmological microscope,polarizing microscope,X-ray powder diffraction and Fourier transform infrared spectrometer,an imitated black nephrite gravel composite stone,which is found in Wuhan Xudong Antique and Jewelry Market,is identified in terms of gemmological,mineralogical and spectral characteristics.The results show that the material is mainly made up of three parts： the black nephelinite,the white tremolite and black organic glue.The differences of the identification characteristics between the imitated and natural black nephrite gravel are that the cross section of the former has obvious signs of composite stone and characteristic infrared spectra organic absorption peak.
