Tairus合成绿柱石的宝石学特征

以泰国曼谷Tairus有限公司生产的Tairus水热法合成绿柱石样品为研究对象，对其宝石学特征进行了测试与研究。结果显示，样品的常规宝石学特征（如RI，相对密度）与其天然绿柱石的相同；肉眼可见其锯齿状生长纹，可作为其合成绿柱石的特征。当这种合成绿柱石产品的内部特征不明显时，可采用FTIR和EDXRF分析技术对其进行诊断性鉴定。

Gemmological Characteristics of Tairus Synthetic Beryl

The study represents the gemmological characteristics of ＂Tairus＂ hydrothermal beryls, which were procured by the Tairus Co. Ltd. The results show that the standard gemmological characteristics, such as RI and SG, overlap with those of the natural counter- parts. Microscopic features, such as ＂chevron＂ growth could readily identify the materials as synthetic which is visible even with unaided eyes. However, there might be cases when the internal features may not identify the material that the FTIR and EDXRF analysis could be needed to conclude the stones as synthetic.
