In terms of mineralogy, jade is divided into two categories, one is nephrite and the other is jadeite. Both nephrite and jadeite belong to the chain citrate. Nephrite is a calcium-magnesium citrate in the hornblende family, so nephrite is also known as hornblende or flashing jade. The jadeite is the sodium aluminosilicate in the pyroxene family, so jadeite is also known as pyroxene jade or jade. Nephrite usually refers to some jade species in China, including: Hetian jade, jade jade, Dushan jade, Lantian jade, etc. Among them, Hetian jade is the best, mainly produced in our Xinjiang Hetian, and has a long history. The best quality, the mineral is a tremolite, Yangshi stone series. The main component is a dense and tough variant of tremolite. Specific gravity 2.9-3.02, hardness: 6-6.5, refractive index: 1.62-1.655, color is white, blue, yellow, red, black and so on. Is a silicate, so it is chemically stable Nephrite Jadeite is a dense block-like aggregate that is closely intertwined by very fine crystals. Moss hardness 6.5 ~ 7. The colors are white, pink, green, light purple, violet purple, brown and black, etc., pure and even, rich and emerald green and fine texture, warm and high. Myanmar is known for its high-quality jadeite, and the United States and the former Soviet Union also have output. Jadeite is defined as a fibrous aggregate composed of pyroxene minerals dominated by jadeite minerals. But jade is not equal to jade. Jadeite is composed of a silicate mineral of sodium and aluminum, which is colorless or white. There are many types of jadeite, and he is different from nephrite. Its ore deposit is produced in the terraces of the Wulu River and its tributaries, and flows from the northeast to the southwest into the pro-Dunjiang River. jadeite The color of nephrite is relatively uniform, with white, dark green, black green, etc., no bright green. It is oily and lustrous and has no greening properties. The proportion of nephrite (3.00) is slightly lower than the proportion of jadeite. The refractive index of nephrite (1.62) is also slightly lower than that of jadeite.
