The reporter recently learned from the Xinjiang Product Quality Supervision and Inspection Institute that after 10 years of scientific research, the Hetian jade sample as a Chinese treasure has already had national standards. This is the first national standard for the release of Hetian jade in China. It will provide a physical reference to the trading of Hetian jade in China, which will greatly promote the development of the industry.
It is understood that Hetian jade national standard samples are classified into six categories: white jade, green white jade, sapphire, jasper, sugar jade and ink jade. Compared with the local standard of Hetian jade physical samples implemented in Xinjiang on June 1, 2010, the national standard of Hetian jade samples has fewer classifications of “Yanzhi Baiyu†and “Yellow Jadeâ€.
Lan Yuping, chairman of Urumqi Houdexuan and Tianyu Cultural Development Co., Ltd., said in an interview with reporters that the value of a piece of Hetian jade should be identified from the five sequences of seed, quality, color (skin), weight and land. And assessment. To put it simply, it is to distinguish between what kind of jade material is, what kind of fineness its texture is, what kind of color is the skin color of jade, what is the weight, and finally where is the origin of this jade material? . Lan Lanping said that many people nowadays, when talking about the value of jade materials, overemphasize the fact that the best seed material has reached tens of thousands of yuan, but avoid the weight requirement of the seed material that reaches this price. This precondition of 20-200 grams is reached.
