This small and remote deposit has produced the gemmiest cassiterites of China, and since the old Bolivian material of olden days. But, it remains seldom known and specimens very few compared to those from Ping Wu in Sichuan Province - which have another habit entirely. This is a sharp, very gemmy and translucent crystal cluster showing the gemminess and luster that make these cassiterites so desirable. The piece has very minor (and in situ) edge wear, and is complete on 3 sides, with matrix attachment in back. It has razor sharp edges on the left and right. NOTE last shot shows the piece strongly backlit.
