宝石学

Jadeite Jade, as a kind of Jade with high quality, has many excellent gemological characteristic, such as gorgeous and changefully color, the tightness and the hardness of its texture, beautiful luster and transparence, and good toughness. Those characteristics attribute to its petrological and mineralogical characteristics.
