Hetian Yushan material identification
Hetian Yushan material identification refers to the broad distinction between Qinghai mountain material and Russian mountain material.
Qinghai jade is a single mineral jade composed of microcrystalline tremolite aggregates. The tremolite content is mostly greater than 99%, and the impurity minerals are less. It has the characteristics of different origins: gray-white-white, yellow-gray white jade, stone flowers, brain flowers, flocculent flowers, waterline, water-spotted, scorpion-like spots, high transparency White jade, the hardness is slightly lower; mainly based on mountain material, a small amount of mountain water material (Gobi material) is produced, but no seed material is found; the visual feeling after polishing is water gas rather than oily, perspective I saw a waterline (jad) in Yuli, and Hetian Baiyu did not. Qinghai jade is mainly white jade, and there are many scorpion-like stripes inside, which are relatively easy to identify. This is an important feature that Qinghai jade will not be mixed with Hetian jade.
Russian jade is very similar to Hetian jade. From the physical properties, both of them belong to the tremolite class, and the composition is not much different. Moreover, the quality of Russian jade is also good, the price continues to rise, and some of the best products are not lost to Hetian jade. This has a subtle effect on the identification between the two.
From the source of jade material, 95% of Russian jade is mountain material and seed material, but relatively speaking, seed material is relatively rare in the market. Compared with Hetian Yushan, the Russian materials are less dirty (impurities), cotton, and sputum, and are very white. A large Russian material often has no dirt, cotton, or sputum. Relatively speaking, Hetian Yushan material has more dirty (impurities), cotton, and enamel.
In terms of jade, ordinary Russian materials are very white in color, but they give people a feeling of dryness, death, and rigidity, lacking oiliness and delicateness. If you look closely at the internal structure, you will find that Russian jade is like a piece of cotton, and Hetian jade seed is very delicate. With a strong glaze, the internal structure is porridge-like and oily. The difference in this composition is actually more fundamental and more precise. We used to evaluate a good jade in ancient times. We must talk about whether it is warm or not. In fact, it is delicate and oily. For example, we use the white fat jade as the top grade of jade. In addition to the color, we must also moisturize. Russian jade is precisely white, but lacks oiliness. With the use of oil-free one measure, Russian jade and Hetian jade are judged high, and the specific jade pieces are generally distinguished. 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.
Hetian Yushan material price
Hetian jade is one of the more popular collections. From 1990 to 2006, Hetian jade purchase price increased by 1111 times.
In February 2012, a piece of Hetian jade weighing 25.5 kilograms in Wuhan rose from more than 200,000 yuan in 1986 to 500 million yuan.
In addition to the factors of hype, the real reason for the rise in the price of Hetian jade does exist. With the mad exploitation of Hetian jade, the sheep fat jade seed material has basically been met. Because it is too scarce, jade is an important part of Chinese cultural genes. More and more people love jade and can afford jade, which makes Hetian jade more and more expensive.
The soaring price of Hetian jade has caused serious damage to the ecological environment of the Yulong Kashi River. The local government has banned disorderly and illegal indiscriminate excavation, which makes the jade raw materials flowing into the market even rarer. In addition, the influx of hot money into the art and collectibles investment market has also boosted the price of Hetian jade.
Hetian jade is a rare mineral resource in China and a non-renewable mineral resource. Its value is unique because of its unique quality, hard work of mining, rare in the world, the color and moistness of jade, the exquisiteness of carving, the size of jade pieces, the value of the collection and preservation, the market demand space and appreciation potential are very Big, the price of Hetian jade has increased to varying degrees every year, especially for fine products, and the rate of appreciation is doubled every year. Investing in the collection of “stones†is risky and should not follow suit blindly.
