Abstract: The nephrite was first found in Nanping, Fujian recently. The primary studies show that Nanping nephrites have white to light green color, RI of 1.61-1.62, density of 2.979- 2.989 and hardness of 6.0- 6.1. The nephrites consist simply of tremolite, but sometimes some diopsides. The chemical compositions of the nephrites are close to the theoretical value of tremolite, with low content of FeO. Comparing to XinJiang nephrites they have a stronger 3671cm-1 hand in their IR spectra, which might indicate their lower content of F. Nanping nephrite occurred in Precambrian metamorphic rocks, marble and diopside marble, and was formed through the regional metamorphism.
