What are the characteristics of real Hetian jade?

Hetian jade color seal Wenrun Guangjie texture tough jade is superior to other jade due to the birth of Xinyi in ICJ (now Hetian) and Hetian jade has been loved by the world for its outstanding jade. Recently, China Bao The Jade Association recommended it as a Hengshi variety, but the definition of Hetian jade has always been controversial in the jade world. From the geological point of view, Hetian jade has a clear scientific meaning, including a variety of soft jade series represented by jade. Produced in Kunlun Mountain, China, the soft jade deposit formed by the contact between magnesia and the acidic magmatic rock (Tang Yanling et al. 1994; Yang Boda 1996) can be seen from the characteristics of Hetian jade:

(1) It belongs to nephrite, and there are a series of varieties such as jade, topaz, sapphire, and jade, especially from jade;

(2) The nephrite deposit belongs to the type of contact metasomatism;

(3) The above-ground distribution is typical of Kunlun Mountain. It is different from other nephrite mines in the world. It has a unique position in the world of nephrite. It has typical significance. The nephrite varieties found in other parts of the world are single, and most of them are jasper. Only Hetian jade has a variety of varieties, especially in the world of jade, and the jade is the world's crown of nephrite. Hetian jade usually refers to the soft jade produced by Hetian. The Chinese nation created by Hetian jade has a glory for seven thousand years. The jade culture is also unique in the world.

The Chuanyu jade seed material has been washed and honed in the river bed for thousands of years. It is naturally smashed, it will color in the soft texture and penetrate the texture in the cracked place. This skin color is very natural, called live skin. The color on the skin should be from deep to light, and the color on the crack should be from shallow to deep. The brown pine-like, water-grass-like color intrusion appears.

Not only can the fake skin be pretending to be a seed material, but it can also cater to the tendency of the love jade to enjoy various skin colors. The jade is generally placed in a dye-impregnated sponge to achieve ochre by erosion and penetration. Most of the fake skin color is jujube red skin, which generally floats on the surface, the color is too bright, there is no transitional natural layering, and it is dry and not moist. At the same time, the fake skin is in the loose area of ​​jade, also known as dead skin. This skin color is easy to fade and fade with hot water.

The rounding of the rolling material is to put a small piece of the lower material of the mountain material, the Qinghai material, the Russian material and the jade jade material into a roller machine, and grind it into an oval shape, which resembles a seed material, and then dyes it to make a fake leather. What's more, the large piece of mountain material is cut into small pieces and then polished in a ball mill for imitation of Tianyu seed.

Due to the prosperity of the Hetian jade market in recent years, many fakes, defective products and Tianyu have entered the market in a large amount, so we have to face a very serious problem, that is, how to distinguish the authenticity of Hetian jade.

At the time of identification, the jade can be aligned with the light source. Since Hetian jade is transparent to the naked eye, when the light is illuminated, the back of the jade can be shaken with fingers to see the shadow of the shadow. And the fake Hetian jade, even if it looks at the light, the jade looks very turbid, and the jade is generally thick, the color is too dead, and there is no feeling of "warm and jade". Through this trick, it is easier to identify the authenticity of Hetian jade. In addition, if the conditions permit, you can use a small knife to engrave a few times. Because the real Hetian jade has a high hardness, if the silk is not infiltrated, it can be judged as Hetian jade. In addition, the authenticity can be discerned by tapping. True Hetian jade is crisp and powerful when tapping, while fake is dull. The master also reminded that in recent years, some people even used artificial glass to pretend to be Hetian jade, so as to lie to the inexperienced consumers. The way to identify is to put the fake on your face and you will feel that the temperature is not as cold as the original.

Through the above methods, we can effectively verify the true and false of Hetian jade to a certain extent, so that we can also reduce the possibility of being deceived in the mall.
