The Shoushan stone (agalmatolite) is one of craft carving stones with great reputation in China.The testing results of the X-ray diffraction and inf ra red spectrum show that the major composition of Shoushan stones is composed of k aoline minerals, pyrophylite and illite, in which the kaoline minerals, particul arly dickite and dickite's and kaolinite's transition minerals, are in majority . The analysis results indicate that the nacrite is discovered not only in Tianhua ung stone ( the highest-grade Shoushan stone) but also in the Jimuwo stone ( o ne of ordinary Shoushan stones) which is derived from the primary ore of the Shous han stone.
