碧玺充填探讨

Research on Filling Treatment of Tourmaline

采用宝石显微镜、红外光谱仪和荧光能谱仪对广州市荔湾广场的105件碧玺样品进行了测试分析。结果表明,绝大多数碧玺样品都存在充填处理的现象,其内部充填物为黄色与白色絮状物,并具有蓝色闪光、流动构造等特征;其中,充填现象不明显的碧玺样品在红外吸收光谱仪和荧光能谱仪下也可检测到有机物及Pb。

The 105 tourmaline samples collected from the different merchants from the Liwan Plaza in Guangzhou City are studied by using the gemmological microscope, IR and XRF. The results indicate that the most of the tourmaline samples have the filling phenomenon, where the fillings are yellow and white flocculus, with the characteristics of the blue flash and flow structure. Meanwhile, the organics and Pb also could be found by the IR and XRF in the samples which have unnoticeable filling phenomenon.
