Discussion on Identification Method of Faceted Ruby from Mozambique under Non-Laboratory Condition

  • 摘要: 红宝石的产地对其市场价格有着较大的影响,本文总结了在非实验室条件下仅用便携式仪器识别莫桑比克红宝石的方法。结果显示,莫桑比克红宝石颜色范围广,较其他产地(缅甸、泰国、斯里兰卡)红宝石的饱和度高但明度较低;目前无星光红宝石品种;荧光强度不一;10倍放大镜下可见点状、针状包裹体的强反光等特征。同时,对非实验室条件下识别刻面莫桑比克红宝石的方法进行可行性分析,对莫桑比克红宝石样品的光学特征、光谱特征、内含物、化学成分等进行测试,结果表明,莫桑比克红宝石中Cr、Fe的质量分数变化较大,并影响颜色色调、饱和度及荧光;莫桑比克红宝石的内部常见沿生长带分布的尘埃状包裹体,针状、楔状金红石及管状出溶的水铝矿包裹体,包裹体组合及样式与其他产地明显不同。因此,非实验室条件下识别刻面莫桑比克红宝石的方法具有一定的可行性,但包裹体种类以及如何更准确地鉴别等方面还有待深入研究。
    Abstract: The locality of ruby has a great influence on the price in the market. In this paper, authors summed up several methods for identifying ruby from Mozambique with portable instrument under non-laboratory conditions: (1) The colour of ruby from Mozambique has a wide range, mostly with high saturation and low brightness; (2) The star varieties with commercial quality has not been reported so far; (3) The fluorescence varies; (4) Typical inclusions are point-like and needle-like solid inclusions, visible strong reflection of inclusion under 10 magnifier. The authors verified the validity of the methods through the study of optical characteristics, absorption spectrum, inclusions and chemical composition and the results showed that Cr and Fe contents in ruby from Mozambique change greatly and influence ruby’s colour and fluorescence. Dust-like inclusions along the growth zone, needle-like or wedge-like rutile and tube-like exsolved hydrargillite commonly are always seen in the ruby. The randomly distribution of inclusions and the lack of needle-like rutile lead to the lack of star species for commercial request. To sum up, the identification method of facet ruby from Mozambique under non-laboratory condition has a certain degree of feasibility, however inclusion variety and exact identification need in-depth study.
