一种新方法处理软玉的鉴定特征

首次报道了一种拼合处理的软玉及其鉴定特征。通过常规宝石学测试、红外光谱和X荧光能谱分析,对该类样品进行了鉴定。结果显示,从外观上,样品的＂皮＂与主体结合处的颜色分界截然,有明显的粘结痕迹和大量的蜡与气泡;拼合面两侧区域的红外光谱完全不一样;X荧光能谱显示,其＂皮＂较主体部分缺少Ca峰。根据测试结果认为,样品应为染色岫玉软玉拼合石。

Identification Characteristics of a Sort of New Treated Nephrite

The composite nephrite and its identification characteristics are firstly reported in the article.The samples are identified by using the conventional gemmological test,infrared spectrum and XRF analysis.The results show that the colour at the interface between the surface part and the main body part of the samples is obvious in the appearance,with the obvious cohesive marks.Many wax and air bubbles can be seen in the composite part.The infrared spectra of the two sites at the composite surface are completely different.X-ray fluorescence spectrum shows that the surface part has no Ca spectrum,and the main body part contains a lot of Ca.The sample is considered as the dyeing composite stone with serpentine and nephrite acorrding to the testing results.
