摘要
针对近期瑞丽珠宝市场上出现的商贸名称为“泰国猫眼”的饰品,采用常规宝石学测试、红外吸收光谱、拉曼光谱、X-射线荧光光谱、紫外-可见光谱对其材料属性、物质成分及鉴定特征进行研究。红外光谱及拉曼光谱测试均显示非晶态SiO2的振动模式特征,表明为一种人工玻璃制品,具有平行纤维状结构及黑色长针状包体。化学成分分析表明主要组分为SiO2,约占70.25%,次要组分有PbO、K2O、CaO、Al2O3、Fe2O3、BaO、MnO、ZnO,其金黄体色由微量的Fe、Mn元素所致。依据国标《珠宝玉石名称》GB/T16552-2017应定名为玻璃猫眼。区别于普通玻璃猫眼的特征是具有“乳白-蜜黄”效应,从侧面透光观察可见到大量分布稀疏的多边形的褐-黑色斑点,无“蜂巢状”纤维结构。
Recently,a new kind of gemstone with the trade name of"Thailand cat's eye"appears in Ruili jewelry market.Conventional gemological testing,infrared spectrum,UV-visible spectrum,Raman spectrum,X-ray fluorescence spectrum methods are used to study the material properties,material composition and identification characteristics of the samples.The results of infrared spectra and Raman spectra show the vibration mode characteristics of amorphous SiO2,indicating that it is a kind of artificial glass product with parallel fibrous structure and black long needle inclusions.Chemical composition analysis shows that the main constituents are SiO2,accounting for about 70.25%,and the secondary components are PbO,K2O,CaO,Al2O3,Fe2O3,BaO,MnO,ZnO.Its gold luteal color is caused by trace Fe and Mn elements.The sample shall be named as Glass Cat eye according to Gems-Nomenclature GB/T16552-2017.It is different from the ordinary glass cat's eye for that it has the"milky white-honey yellow"effect,and a large number of sparsely distributed polygonal brown-black spots can be seen from the side through light,without the"honeycomb"fiber structure.
