Ancient China attached great importance to the color of Hetian jade. It is not only an important symbol of quality, but also attached to a certain ideology. The ancients may be influenced by the Five Elements. According to the Quartet and the Central Committee, the five colors of jade are distributed, the east is green, the west is white, the south is red, the north is black, and the center is yellow. In ancient times, the five colors of cyan, red, yellow, white and black were positive colors, and the others were intercolored. Thus jade is also divided into five colors. The color of jade contained in Wang Yi's "Jade Theory" is: "Red as a cockscomb, yellow as steamed chestnut, white as a cut-off fat, ink as pure paint, and a jade symbol. And sapphire has nothing to say. Today's white people often have, There are black, but there is no such thing as the yellow. This means that jade has five colors of white, cyan, black, red and yellow, and is usually cyan and white. Fu Heng and other 纂 "Western Maps" said that the jade from the Yuyu River is: 绀, yellow, green, blue, white color. Li Yuan’s "Western Regions Wen Cun" said that the jade produced by Yarkant is different in color, white, yellow, red, black and blue. The above said that there are five colors of jade, but the Ming Dynasty scientist Song Yingxing believes that jade is only white and green. He said in "Heavenly Creations": "Where jade is only white and green, green Chinese famous dishes Jade, its red jade and yellow jade, all of them are stone scorpions, the price is not jade, but not jade. "The ancients said that the jade color is not the same, after our investigation and jade jade actually only white, blue, ink, yellow Four-color. In addition, in some areas of the Kunlun Mountains and the Altun Mountains, jasper is also produced, which is also a nephrite. The genesis is related to ultrabasic rocks, similar to the Canadian Jasper and the Xinjiang Manas Jasper, but it can also be attributed to the Saitama range. Different colors of jade, the quality is not the same, such as "Xinjiang Gegu Theory, Treasures" said: "Jade out of the Western Regions in the country, there are five colors ... where the utensils are white, yellow jasper is also expensive." China White has been a symbol of purity since ancient times. "Han Shu Heng Heng": "Shows white people." So people love white. White jade is not only white in color, but also in good texture. Deep people love it and are listed as treasures. Now, according to the color of the jade jade, it can be divided into white jade, white jade, sapphire, jade, topaz, jasper, and jade jade. Other colors and jade can also be divided into small varieties.
