摘　　要：由于市场上出售的玫瑰石缺少统一的规范和标准,常引起玫瑰石交易的混乱。本文采用电子探针和 拉曼光谱等大型仪器,并结合显微镜放大观察、折射率测定、净水称重、荧光观察,对玉石市场上三种典型商售“玫瑰石”玉石的成分、谱学特征及常规宝石学鉴定特征作了对比分析和研究。结果表明,菱锰矿、蔷薇辉石和红柱石可以通过外部特征、荧光、折射率等方面进行基本区分,三种“玫瑰石”玉的电子探针和拉曼光谱测试结果都有明显区别,菱锰矿的主要矿物成分为菱锰矿,含有石英条带;蔷薇辉石的主要组成矿物为蔷薇辉石,红柱石主要矿物为红柱石,包含白云母、黑云母、石英等次要矿物成分。拉曼测试显示菱锰矿样品具有1075cm^(-1)、1086 cm^(-1)、291 cm^(-1)、179cm^(-1)的特征拉曼位移,蔷薇辉石样品有 1006cm^(-1)、668 cm^(-1)、300cm^(-1)的特征拉曼位移,红柱石的特征拉曼位移在 1060cm^(-1)、950cm^(-1)、545 cm^(-1)、300 cm^(-1)附近。本文对三种“玫瑰石”玉的分析可以为珠宝从业者和消费者提供有效的鉴定依据。The lack of unified norms and standards for the "rose stone" as jade often causes chaos in the rose stone market. This paper has a discussion on gemological characteristics of three typical rose stone as jade such as rhodochrosite, rhodonite and andalusite. The rhodochrosite as jade consists of rhodochrosite and a small amount of banded quartz. The andalusite as jade consists of andalusite and a small amount of muscovite, biotite and quartz. Rhodonite is characterized by 1006 cm^(-1), 668 cm^(-1)and 300cm^(-1)Raman lines shifts, rhodochrosite is characterized by 1075 cm^(-1), 1086 cm^(-1), 291 cm^(-1)and 179 cm^(-1)Raman lines shifts and andalusite is characterized by 1060 cm^(-1), 950 cm^(-1), 545 cm^(-1)and 300 cm^(-1)Raman lines shifts.
