天然蓝玉髓是中国台湾所产的名贵宝玉石之一,素有“台湾蓝宝”的美誉。但是世界上此种蓝玉髓的产地不止宝岛台湾一处,此外还有印度尼西亚和美国等地。三地所产蓝玉髓在常规仪器下检测无明显区别,所以本文通过红外反射光谱和激光拉曼光谱等大型测试仪器【1,3】,对不同产地的蓝玉髓的振动光谱特征进行了研究。结果表明,以上三个产地的蓝玉髓确实存在着差别特征。 Natural blue chalcedony is one of the precious gemstone produced in Taiwan, China, known as “Taiwan’s Sapphire ” in the world. However, the origin of this kind of blue chalcedony in the world is not only one in Taiwan, but also in Indonesia and the United States. The blue-chalcedony produced by the three places has no obvious difference under the normal instrument detection. Therefore, the vibrational spectral characteristics of blue-chalcedony in different areas have been studied by the large-scale testing instruments such as infrared reflectance spectroscopy and laser Raman spectroscopy [1, 3] the study. The results show that there is indeed a difference between the above three areas of blue chalcedony.
