具有白色条带的粉红色翡翠的宝石学特征

Gemmological Characteristics of Pink Jadeite Jade with White Ribbons

  • 摘要: 目前在香港翡翠市场出现了一种具有白色条带的粉红色翡翠。采用偏光显微镜、电子探针、拉曼光谱、红外光谱、阴极发光等测试技术,对其白色条带的形成以及粉红色部分的致色成因进行了较全面的宝石学特征分析与研究。结果发现,白色条带是由于剪切应力而呈碎裂结构形成,粉红色部分是由含极少量Mn和Fe元素而致色。

     

    Abstract: At present the pink jadeite jade with white ribbons is on sale in the market of Hongkong. The formation of the white ribbon and the colouration mechanism of the pink part are studied by using the polarizing microscope, electron microprobe, Raman spectrometer, infrared spectrometry and cathodoluminescence, etc. The results indicate that the formation of the white ribbon is caused by the shear stress to be cataclastic texture and the pink part of the jadeite jade is coloured by a very few of Mn and Fe.
