Recently, a new kind of gem product whose business name is "Cuihua Jade" appears in the jewelry market. It contains purple, green and white parts and is easily mistaken for nephrite. The authors chose three samples, used conventional gemological methods and polarizing microscope to investigate their gemological characteristics and mineral components, and then employed XRD and EPMA to emphatically probe into their mineral components. The results show that the "Cuihua Jade" is a kind of multi-mineral aggregate jade and of metasomatic origin, with its main mineral components being diopside, tremolite, fluorite, quartz, plagioclase and calcite, in which the tremolite exhibits network distribution in the sample. The refractive index of the green part is 1.61 (point measurement), and that of the purple part is 1.43 (point measurement). The average density is about 3.03 g/cm³. The color of the sample is mainly caused by purple fluorite and green tremolite.
