According to the traditional classification, Yangzhiyu is the best of Hetian Yuzhong, “Gem-grade materialâ€, which is only produced in Xinjiang in the world and is only present in the seed material. The reason why it is called sheep fat jade is because its appearance is white, the texture is fine, the gloss is moist, and it shows a strong sense of grease, and even the feeling of not grasping and fearing. From the physics point of view, the content of tremolite in sheep fat jade is more than 99%, far from the reach of other nephrites, so it is extremely rare and precious. Now the real sheep fat jade can be said to be few and far between, it is difficult to see on the market, even if it is, it is only limited to "circle" circulation, and the price is very high, it is said that each gram has reached 30,000 to 50,000 yuan. And it is not something that can be obtained without money, because the owner of Yangzhiyu is mostly "not bad money". If you want to transfer it to your hand, you have to see if the transferor is willing. In recent years, there has been a Russian material on the market, which is called black leather because of its black skin. Some of these materials are almost comparable to Hetian jade fat jade, and have become the object of pursuit by players for a time. The price has skyrocketed. The price of kilograms has risen from tens of thousands to the current seven or eight hundred thousand, and there is still no "brake". meaning. It seems that in the case of the increasingly scarce of Hetian Yangzhiyu, black leather as a material that can satisfy people's "salt desire" is also an alternative and supplement.
