摘　　要：本实验室接收了一件蓝绿色与白色相间的手串,其表面色调呈现出不均匀的块状分布特征,并伴随有网格状的纹理。该手串与针钠钙石的外形极为相似,商家以针钠钙石进行销售。为深入探究该试样的物质成分及微量元素含量,通过常规的宝石学仪器设备,对其折射率、密度以及发光特性等关键指标进行了详细的检测与分析。此外,还借助了Nicolet iS5型傅里叶变换红外光谱仪以及X射线荧光能谱仪等先进设备,对该样品进行了深入的科学研究。经过综合分析与比对,研究结果显示:该样品的折射率为1.51(点测法),相对密度为2.10。红外光谱分析进一步证实,该样品实质上属于玻璃材质,其主要致色元素为铁(Fe)。根据《GB/T16552-2017》的相关规定,该样品的定名应为仿针钠钙石或玻璃。The laboratory received a beaded bracelet with an alternating blue-green and white color,exhibiting an uneven blocky distribution on the surface,accompanied by a grid-like texture.The bracelet closely resembles the appearance of a sodalite,and is marketed as such by the vendor.To further explore the material composition and trace element content of the sample,routine gemological instruments and equipment were used to conduct a detailed examination and analysis of key indicators such as refractive index,density,and luminescence characteristics.Additionally,advanced equipment such as a Nicolet iS5 Fourier Transform Infrared Spectrometer and an X-ray fluorescence spectrometer were employed for in-depth scientific research on the sample.After comprehensive analysis and comparison,the results showed that the refractive index of the sample is 1.51(measured by the point method),and the relative density is 2.10.Further infrared spectroscopy analysis confirmed that the sample is essentially made of glass material,with iron(Fe)as the main coloring element.According to the relevant provisions of the"GB/T16552-2017"standard,the sample should be named as imitation sodalite or glass.
