| 摘 要： | 绿松石属于中档宝石，传统的绿松石定性分级方案比较粗略，对绿松石的颜色的分级采用的是肉眼分级。笔者采用Gem Dialogue颜色分级标准对14粒绿松石戒面进行了颜色评价．并以颜色、铁线、质地、切工为评价因子对样品进行了定量化分级。在与市场价格的对比中发现。采用定量化分级标准所得出的绿松石样品的质量指数符合市场调查所反映的绿松石样品的价格的变化趋势。绿松石常呈集合体出现，且结晶程度不一，颗粒大小不等，颜色、致密度、透明度常不一致，因此文中采用的量化分级必须建立在分类细化的基础上。

| Abstract: | Turquoise is a mid-class gem. The evaluating of the turquoise's quality given by the gemologists before are always roughly . The evaluating of the turquoise's color also is always given by naked eye. In virtue of Gem Dialogue classification rules on color, the paper graded the 14 turquoise samples according to color, pattern, texture and cut. Compared to the samples' marketing prices, the result of the turquoise samples given by quantitative-analysis is corresponding. The turquoise always appears aggregation, its color, texture, transparence are different from high-class to inferior-class. So, the quantitative-analysis about the turquoise has some limits. |
