Mount Xuebaoding, a huge mountain located in western China's Sichuan Province on the Tibetan Plateau, is known for producing the world's finest crystals of scheelite, and has also produced what many consider to be the world's best cassiterite crystals. Now largely mined-out and in danger of permanent closure due to expansion of an adjacent nature reserve, Mount Xuebaoding is producing very little to no new major specimens. This is a superb, very large lustrous black cassiterite crystal on muscovite matrix, showing complex twinning and aesthetic placement on the matrix. An excellent example of this tin mineral from a major locale for the species. Ex - Proctor Family Trust Collection.
