China has traditionally been a territory of a great conundrum with a diversity of natural resources including minerals and gems, and especially green colored stones (e.g. jade, prehnite and peridot). Peridot has been found in a number of different areas of China. Since 1979, China has mined the peridot from the Zhangjiakou-Xuanhua area of Hebei Province (Koivula and Fryer, 1986; Keller and Fuquan, 1986). Recently, the significant deposit of gem-quality peridot has been found in the area called Yiqisong, Yanbian of Jilin province. At first glance, these peridots strikingly show a medium toned yellowish green attribute with high clarity. The average size of relatively clean stones was up to 2 ct. This article describes their detailed gemological characteristics, namely, basic properties, internal features, absorption spectra and chemical compositions.
