Product name: Authentic Jade Pi Disc with Natural Jadeite Stone, Certified Green and White Donut, Chinese Amulet 55mm in diameter. The word Jade refers to two different minerals: Jadeite and Nephrite. To be considered Jade, both must form very fine granules or intertwined fibers. The Nephrite Jade, very common in Asia, is often called Chinese Jade, since it makes beautiful pieces carved with various motifs such as Buddhas, dragons, as well as some oriental symbols. Large deposits of Nephrite Jade are found in places such as: British Columbia, Canada; Alaska and Wyoming, the United States; Australia and New Zealand. Jadeite Jade is the other type of Jade identified by Gemologists, which is a rarer and more difficult to find type of Jade. Basically, it can be found in four places in the world: Myanmar or Ancient Burma, Japan, Russia and Guatemala.
