Types of Jade
Nowadays the world can touch on hundreds of jewelry classes of jade, such as Hotan (tian) Jade, Qinghai White Jade, Jasper, Russian and Canadian Jasper. Chinese people love the color of pure jade but North Americans enjoy the slightly flawed ones since they believe if the chromite spot on the jade is rather unique. International jades can be distinguished from the mineralogical point of view. "Jade" actually includes two different types of minerals: amphibolite jade nephrite (Mohs hardness 6-6.5), and Hui Yu Shi "jadeite (Mohs hardness of 6.5-7). Both of which are formed under high pressure and low temperature conditions, the infiltration of different elements in the process resulting in a different color.
- Some nephrite common colors are white, yellow, brow, grey, dark green, and a color close to the beauty of wax cream.
- Nephrite jade is produced in Xinjiang Hotan region or also known as "Tian Yu", white mutton, fat jade, the most delicate and moist type of jade. The most precious varieties of nephrite are produced mainly in China and in northern British Columbia where they are called Canada nephrite jade. The nephrite physical and chemical traits are rather consistent with the color tone of a soothing greenish color. Most of the minerals contain jasper unique black spots. Then we have the best rare mineral in the Arctic where the jade has smooth, fine texture that is also a bit moist. Dicui, a green jade has the best varieties of many nephrites.
