摘要：
Gemstone deposit is an interdisciplinary subject in ore deposit geology and gemology, it establishes an important bond between gemology and geology. As part of the earth material, gemstone represents a beautiful part of minerals and rocks from our mother planet. In addition, it is an important object of research for exploring composition, characteristic and evolution of the earth. With deeper understanding of gemstones' origin of characteristics and effects, accompanied by the discovery and application of new gem varieties, gem deposit has become an informative discipline both in geology and gemology. In this investigation, the history and development of gemstone deposit are reviewed; distribution of gem resources is summarized; and a brief discussion on gem mineralization is presented. We believe it is essential to study gem mineral and gem rock mineralization in order to understand gemstone deposit well, but one also needs to study the formation process of forming jewelry-class gem and jade. In addition, there are quite a number of researches focused on the formation mechanism of gem's characteristics and effects, such as play color, aventurescence, alexandrite and moonlight effects, but there are much to be learned on how these mechanisms are realized in nature. In general, research contents of gemstone deposit are incomplete and nonsystematic that the formation mechanisms of many gemstones are still under speculation. It is predicted that for a long time to come, researches in gemstone deposit will be focused on the data collection and documentation of individual deposit cases, as well as comprehensive analogical analysis comparing similar gemstones from different locations. © 2017, Editorial Office of Earth Science Frontiers.
