一种砂金石英的包裹体研究

Study on the inclusions of the aventurescence effect quartzose jade

砂金效应是宝石的特殊光学效应,系内部的片状包裹体反射形成的闪烁现象。近期国际市场出现一种乳白色的具有明显砂金效应的宝石。通过常规宝石学测试,结合红外光谱仪、显微拉曼光谱仪等测试手段,认为该宝石为一种石英质玉石,其砂金效应系由内部大量的片状石墨包裹体反射形成。

The aventurescence effect is a special optical effect of gemstones,which is a scintillation phenomenon formed by the reflection of the internal lamellar inclusions.Recently,there is a milky white gemstone with obvious aventurescence effect in the international jewellery market.Through conventional gemological testing,combined with infrared spectrometer,microscopic Raman spectrometer and other testing methods,it is believed that the gemstone is a kind of quartzose jade,and its aventurescence effect is formed by the reflection of a large number of internal graphite inclusions.
