| 摘 要： | 俄罗斯水热法合成祖母绿是珠宝界较关注的产品。选用5粒俄罗斯水热法合成祖母绿样品进行了常规宝石学特征测试、电子探针成分分析、红外吸收光谱和紫外-可见吸收光谱测定。结果表明，俄罗斯水热法合成祖母绿样品以低碱、富Fe与Cr为特征，折射率和相对密度明显偏高，红外吸收光谱特征峰出现在4052cm叫附近；俄罗斯水热法合成祖母绿样品的致色元素为Cr与Fe。同时，对比分析了俄罗斯、桂林水热法合成祖母绿样品和天然祖母绿样品的宝石学特征。

| Abstract: | The Russian hydrothermal synthetic emerald has caught the attentions of the gemmologists. Five Russian hydrothermal synthetic emerald samples are tested for the conventional gemmological characteristics, chemical compositions, infrared absorption spectra and ultraviolet-visible absorption spectra. The results show that the Russian hydrothermal synthetic emerald samples are characterized by low alkali, rich Fe and Cr and higher RI and SG. In addition, 4 052 cm^-1 is the characteristic absorption peak of the Russian hydrothermal synthetic emerald samples and the colouring elements are Cr and Fe. The gemmological characteristics of the Russian and Guilin hydrothermal synthetic emerald samples are also comparied with that of the natural emerald samples. |
