Although the Huanggang Sn-Fe deposit has received great international reputation due to its production of numerous precious mineral crystal specimens, it is rarely known in China. This paper gives a brief introduction of output features of the mineral crystals in the Huanggang deposit, focusing on the briefly description of the varieties and characteristics of the main output areas such as I,II,V districts. Mineral crystal is a new discipline, which has received wide attention in some foreign developed countries. In contrast, mineral crystal in China is still in the initial stage. Many precious mineral crystal specimens are destroyed or sold off due to ignorance of its value, which lead to huge losses. In the future, it needs to arouse public attention in order to make further development of the mineral crystal research, as well as collection land trade.
