The jade of the ancient jade
Most of the high-grade jade products are made of inferior jade. The important reason is that many high-grade jade such as Hongshan jade, Liangzhu jade, Yangshao jade, and Longshan jade, etc., use a lot of locally produced jade. Instead of or rarely using the jade-quality Xinjiang Hetian jade material, the imitation can use the cheap jade material to imitate the high ancient jade, and even use the colorful stones to imitate the high ancient jade. There are also many low-end imitations. Glass products are used in large quantities, and pigment materials are added to the glass raw materials to imitate the mottled ochre that appears after the jade is damaged. In addition, the high price of Xinjiang Hetian jade material also makes the counterfeiters who pursue profiteering deterred.
The vast majority of Yin Shang jade, the use of Xinjiang Hetian jade material with excellent texture, whether it is "women good" jade, the Yin Shang jade of other unearthed collections that the author once studied, and the Yin Shang jade that the author himself collected, the material is absolutely Most of them are Xinjiang Hetian jade, and only a small part of them use Henan's Dushan jade, Xinmi jade and Liaoning jade jade. Xinjiang Hetian jade is unique in the world of jade materials because of its warmness, compactness, exquisiteness, high hardness and great importance. It has been the first choice for jade carving in China since ancient times, and it is the best in jade, and it is the best in jade. It is already hundreds of thousands of dollars a kilogram. The jade used in Hetian jade carving has the unparalleled crystal and warm characteristics of other jade materials. Because the hardness is around 6.5 degrees, it is not easy to wear.
Because of the preciousness of Hetian jade, most of the replicas of Yin Shang jade do not use Hetian jade, and do not use Hetian Yangzhi Baiyu and Ziyu. From the Han Dynasty to the prehistoric jade, the ancient jade's materials are intricate, but from the Shang Dynasty to the Han Dynasty for more than a thousand years, most of the jade materials of these ancient jade articles used Xinjiang Hetian jade. The jade material of Xinjiang Hetian jade is dense and delicate, the gloss is warm and the hardness is high. Even the glass can be scored. The steel knife is scratched without leaving traces. It is more important. It has the feeling of pressing hands, and the cross section and the damaged surface are uneven. The texture, luster and specific gravity of other jade materials are very different from Hetian jade. It is worth noting that the Russian white jade that appears on the market is very similar in texture to Hetian jade. Many of the replicas have used Russian jade. The biggest difference between Russian jade and Hetian jade is that it is not as warm as Hetian jade.
Obviously, as long as we know that most of the ancient jade since the Shang Dynasty used the basic characteristics of Hetian jade and Hetian jade, the difference between Hetian jade and other jade materials and stones, the true understanding of the high ancient jade in this historical stage. Great help.
Conclusion

Although through continuous practice, combined with the book knowledge of predecessors, When identifying ancient jade, it is less "medicine" and less eye-catching. However, the endless stream of imitation high ancient jade will also "advance with the times", making the ancient jade more difficult to distinguish.
The author believes that we must start to study the authentic ancient jade, and we must also thoroughly study the real jade, and at the same time we must also study the imitation of ancient jade, in order to have the ability to discriminate.
