In general, Xinjiang is considered to be Hetian jade in the narrow sense, Qinghai jade, Russian jade, and Korean jade are “Hetian jade†in a broad sense. However, the difference in quality between the materials and the price difference between them is quite large. How does Hetian jade distinguish between Russian jade and Qinghai jade? First, Xinjiang Hetian jade: Xinjiang Hetian jade is produced in Hetian jade in Kunlun Mountain and Altun Mountain. The subdivision can be divided into mountain material, mountain water material, Gobi material and seed material, among which the seed material is the best. Xinjiang Hetian jade has always been famous, mainly due to its warm color, fine jade, and strong oiliness. Xinjiang Hetian jade has a vibrite content of 95%~99%, which is a blanket-like interweaving structure. The mineral particles are extremely fine and there are few impurity minerals. These are the fine texture of Xinjiang Hetian jade, the density is high, the perception is dignified, and the weight of the hand is heavy. It is an important reason for the strong light and strong color of the oil. Xinjiang Hetian jade has great toughness, is not easy to be broken, and is wear-resistant. It is superior to Qinghai, Russian and Korean in terms of jade carving art and fine carving. Xinjiang Hetian jade has a Mohs hardness of 6.5 to 6.9, which makes it easy to scratch the glass without any damage. It will make a metal-like sound when struck. Second, Russian jade: Russia's production in the Kunlun Mountains extended to the rest of Russia, probably in the early 1990s began to enter the Chinese jade market. Because the origin of Russian materials is very close to Hetian, the quality of all aspects is also the closest to Xinjiang Hetian jade. The jade quality of Russian materials is relatively pure and rich in color. Common colors are white, yellow, brown, brown, green, blue and white, and often a variety of colors are concentrated in a piece of jade carving. From the cross section, the Russian material, from the edge to the center, the color is brown, brownish yellow, yellow, cyan, cyan, white; the mineral particles are also coarse and thin from the edge to the center. At present, many of the pretty color carvings on the market are mostly Russian. Russia does not have a good water head in Qinghai, and it is not as good as Xinjiang Hetian jade oil. The Russian material looks slightly powdery and porcelain-like, some dry, and its color is flamboyant, especially the white jade white over the head. Of course, the good Russian material is also very beautiful, and it is easy to be confused with Xinjiang Hetian jade. However, it is not difficult to find out that the Russian material is slightly looser, slightly thicker and slightly moisturized than Xinjiang Hetian jade. The Russian material is mainly based on mountain materials. It seems that there is no seed material and mountain water material. Therefore, the Russian material lacks the high-quality varieties of Xinjiang Hetian jade seed material and mountain water material. For the sake of operation, the following also summarizes the following: 1. Russian materials are slightly powdery and porcelain, and some are dry. 2, Russian material color is slightly unassuming, white jade white is too overdone. 3, Russian materials white jade, white jade, sapphire often bring some sugar color. 4. In the Russian material, there are more works of more than two colors. Third, Qinghai material: In the early 1990s, Qinghai was discovered and exploited near Sanchakou, Kunlun Mountain, Golmud, Qinghai. Qinghai is mainly based on mountain materials, with a small amount of Gobi materials and mountain water materials. The Qinghai material is translucent, which is more transparent than the “Hetian jade†species of other places of origin. It often presents the white transparent “ribs†unique to Qinghai materials (the old pit materials generally do not have such ribs). The Qinghai material water-permeable (shuitou) Lingxiu and Xinjiang Hetian jade have a sharp contrast, and each has its own characteristics. The hardness of Qinghai material is below 6 and the specific gravity below 2.9 is lower than that of Xinjiang Hetian jade. Especially when it is reflected in Qinghai white material, its fine density and moisturizing feeling are obviously not as good as Xinjiang Hetian jade. After playing, it will show a slight grayishness. Shortcomings. However, the blue and white jade and sapphire in Qinghai are conquered by the jade players with their rich and colorful varieties, elegant and refreshing style, and delicate and uniform texture. In short, Qinghai is one of the very high-quality and very unique "Hetian jade" species. It is much easier to identify than Korean. In practice, we should pay more attention to the following points: 1. The Qinghai material is higher in transparency (water head) than the “Hetian jade†species in other producing areas. 2. Qinghai materials often present their own unique white transparent “ribsâ€. 3, Qinghai white material's fine density and moisturizing are obviously not as good as Xinjiang Hetian jade, after the play will also show a slight grayish shortcomings.
