白玉是和田玉的主要品种之一，首先采用常规宝石学鉴定手段对白玉及其石英岩、大理石、岫玉和玻璃等仿品进行了测试，重点采用激光拉曼光谱仪对它们的拉曼光谱特征进行了测试，结果表明，白玉及其仿品的拉曼谱峰明显不同，其中白玉的拉曼谱峰主要表现在：1059cm-1、1029cm-1和930cm-1是 Si-O的伸缩振动，747cm-1和673cm-1是 Si-O-Si的伸缩振动，528cm-1是 Si-O的弯曲振动，415cm-1、392cm-1、368cm-1、221cm-1、177cm-1、157cm-1和120cm-1与晶格振动有关。

White nephrite is one of the main varieties of nephrite. Firstly, white nephrite, quartzite, marble, serpentine and glass are carefully observed and tested by the conventional gemological testing means. What`s more, with the help of laser Raman spectrometer, their different peak positions, peak shapes and relative strength characteristics of Raman spectra and vibration patterns are described and analyzed. The Raman spectral band positions and assignments for white nephrite are shown as follows:1059cm-1, 1029cm-1 and 930cm-1 are caused by the Si-O stretching vibrations, 747cm-1 and 673cm-1 are caused by the Si-O-Si stretching vibrations, 528cm-1 is caused by the Si-O bending vibration, 415cm-1, 392cm-1, 368cm-1, 221cm-1, 177cm-1, 157cm-1 and 120cm-1 are related to the crystal lattice vibrations.
