The origin of Russian nephrite was also a Chinese territory in ancient times and has now been placed under Russia. The physical properties of Russian materials are basically the same as those of Xinjiang mountain materials. Some of them are relatively transparent. They may be slightly colder, have a colder tone, have a stiff feeling, and have a poor oiliness. Now the price of the best Russian material on the market has exceeded that of Xinjiang. Because Xinjiang has not produced the finest mountain materials for several years, the quality of the new mineral materials produced now is not comparable to that of the Russian. Therefore, the potential for good Russian appreciation is still very huge. From the comparison of Xinjiang jade and Russian jade in the near future, Russian white jade is generally a little redden in terms of mountain materials, while Xinjiang jade is green. Russian jade (Russian jade) Qinghai jade is also a nephrite, because the market price is relatively low, often posing as Xinjiang Hetian jade. However, Qinghai jade and the traditional Hetian jade still have some differences: Qinghai jade is translucent, better than the transparency of the jade, the texture is slightly thicker than the jade, the specific gravity is slightly lower than that of the jade, and the texture is not as fine as Hetian jade. Lack of the feeling of dampness and fatness of sheep fat, often there is a transparent water line; the color of Qinghai material is also slightly wrong, often with grayish greenish yellowish, and also black and white, black and yellow, green and white, green and yellow. The jade material is used as a pretty color. Qinghai jade is basically mountain material. Qinghai jade You should never listen to the jade boss's flickering, what "the processing technology is different, there are polished, there are matt, are sheep fat jade." There is a saying in the line: "Good jade is not polished, good jade is not dyed." Not to buy interior paint, what polished, matt? Yes, since it is a good jade, do you polish it and do it like Qinghai? (A polished and waxed jade can shield the jade from the jade, making the jade look more beautiful, oily and delicate, more like Xinjiang Hetian jade.) Russian jade At present, there is no quality grading standard for white jade in the country (because the composition, whiteness and structural exquisiteness of jade can be measured, and the oiliness and temperature are not defined by quantitative indicators), which causes confusion in the market. There is a local standard for nephrite in Xinjiang. This should be made to introduce Xinjiang jade into the national market and go to the world market. Its standard of sheep fat white jade is relatively low. According to this standard, the superior Xinjiang material, Russian material and Qinghai It is expected that the mountain materials are all sheep fat white jade! ! (Xinjiang mineral rock appraisal agencies are implementing this standard) This is quite different from the standard of sheep fat white jade in our industry! Hetian jade In the true sense, the sheep fat jade refers to the top white seed material produced in the Baiyu River riverbed in Xinjiang and Yutian. However, at present, such top grades have long been basically out of production, and the so-called "goat fats" that we can currently see on the market are mostly the seeds that have been washed away by the snow melting in the Kunlun Mountains of Xinjiang. For the mountain material (or mountain water), the high quality of the material is the same as the seed material. As for other materials such as minerals mined on the Kunlun Mountains, Russian minerals, etc., the texture has been very different from the seed material. The high quality is white, but it does not belong to the real sense of fat.
