1.Xinjiang Hetian jade is not white, nor is it transparent! This is because Hetian jade tremolite has a high content and is made from a combination of minerals! And other jade species in nature are whiter than Hetian jade!
2.After playing with Hetian Yu in his hand for 20 minutes, his hands were very oily.
3.The cleavage on the Hetian jade, which is what people call the cracks, will heal in the pan play!
4.In the process of playing or wearing Hetian jade, the jade will fade back to white, and it will become more and more beautiful! The skin color of the seeds will become more and more gorgeous!
All the jade that meets the above characteristics must be Hetian jade!
Hetian jade is of excellent quality and well-known at home and abroad. In recent years, with the soaring price of Hetian jade, the Hetian jade collection team has been growing. Through years of carving experience and summary, we have mastered a set of practical identification methods for Hetian jade collectors.
One look: look at the gloss, color, transparency.
Luster. Luster is the ability of jade to reflect light. Hetian jade luster belongs to the oil luster - waxy luster.
"Warm and luster" means that the luster has a strong oiliness and a moisturizing feeling. This luster is soft and pleasant to look at. From the overall situation, Hetian jade is stronger than other jade, which is a key point in identifying Hetian jade.
Color. The hues of Hetian jade are relatively rich, with 4 basic tones such as white, cyan, yellow, and black, as well as some transitional colors, such as blue-white, off-white, and so on. In addition, there are many skin colors of Hetian jade, and the use of skin color can be used to make beautiful jade.
Transparency. Transparency is the degree to which jade allows visible light to pass through, and the transparency of Hetian jade is between slightly transparent and translucent, and in general, the transparency of Hetian jade (or "water head") is better than that of Dushan jade, and inferior to Qinghai jade.
Second, take it: feel the weight and heat in your hand.
Weight. The density of Hetian jade is larger, which is greater than that of ordinary jade, and there is a feeling of pressure when holding Hetian jade in your hand. There are slight differences between different varieties, generally Hetian green jade has a higher density, and white jade and black jade have less density.
Heat. Thermal conductivity is the ability of a substance to conduct heat. Any material with strong thermal conductivity can transfer heat quickly. When you touch Hetian jade with your hand, you will have a cold sensation because Hetian jade can quickly spread the heat from your hand.
Three tests: use a knife to cut and test the hardness.
Hardness is one of the important signs for identifying Hetian jade. Jade with high hardness has good polishability, which can make jade shiny and easy to preserve. The hardness of Hetian jade is 6 to 7 on the Mohs scale, which is somewhat greater than that of ordinary jade.
Use a small iron knife (or steel knife) to carve Hetian jade, and the jade body is not damaged. It is also possible to use Hetian jade to carve ordinary glass, and the glass is scratched, while Hetian jade is not damaged, which is not possible with most other types of jade. The hardness of Dushan jade is also very large, but the color of Dushan jade is more mixed, often there are multiple colors on a piece of jade, and the transparency is low, which is easy to distinguish from Hetian jade.
The hardness of Qinghai jade is about lower than that of Hetian jade, and the edges and corners of the single-sided blade of the broken blade are cut, and there will be slight scratch marks. This is a reliable way to distinguish between Hetian jade and Qinghai jade.

National Cultural Market Research and Evaluation Center.
Material is the primary premise of jade collection, and high-quality jade is essential for a piece of jade.
Two: identify the modeling ornament:
Modeling is the framework of jade aesthetics, and it is also an important factor in determining the value of jade collections
The jade process is a technical condition for changing materials into utensils, and its properties are relatively stable and not easy to be truly recognized, which is a difficult problem in appreciation. Where the work is neat and smooth, skilled and seiko must be beautiful or relatively beautiful, on the contrary, the board is sluggish and weak, dragging mud and water, it is a sign of a sharp decrease in the value of the collection, and it cannot be collected.
Four: Try to buy skin color jade:
Hetian Ziyu is a layer of maroon or brownish yellow jade skin distributed on the outside, so it is customary to call it skin color jade. There are autumn pear, reed flower, jujube red, black and other colors, jade artists with a variety of skin colors named jade, such as autumn pear skin, tiger skin, jujube skin red, sprinkled golden, black skin and so on. Many jade stones in the world have this color, but they are not as beautiful as Hetian jade.
Buying skin color jade has the following advantages:
1.Ziyu with steel seal (national appraisal certificate) is not controversial and can determine its value preservation and appreciation.
2.There is a saying in the industry: "The material is gone, and the fairy can't recognize it." It mainly refers to some high-quality mountain materials (even Russian materials) that can be compared with sub-materials, and are filled with **** by unscrupulous businessmen, but the purchase price is several times different.
At present, the Hetian jade that can be seen on the market mainly includes Xinjiang Hetian materials, and the end materials, Gobi materials, etc., which are all authentic Hetian jade. In addition, there are Russian materials and Qinghai materials, which are collectively known as Hetian jade. There are also many unscrupulous merchants who use Afghan jade or even quartzite to pass off as Hetian jade. >>>More
