On a Weibo, I saw an appraisal sticker, and He Tianyu took out a new imitation...
This time, the replica, called wollastonite, is said to have appeared in the market for a long time, but it is not very common. The refractive index is 1.62 and the specific gravity is 2.93, which is completely the same as that of Hetian jade. Their difference is that the hardness is low, around 5, the gloss is a little waxy, grainy structure. Therefore, when distinguishing, it can be distinguished by the difference between gloss and structure.
The Chinese people’s feelings for Hetian jade are really inexhaustible. It is said that at least in the late Shang Dynasty (about 13th century BC), the seed jade produced by Baiyu River has been imported into the Central Plains in large quantities, and it has been made into a beautiful jade. Looking at the world, China's jade culture is also standing out from the crowd!
People are eager for Hetian Yutai. On the one hand, it leads to the high price of Hetian jade, on the other hand, it brings a variety of imitations that are incomprehensible. For this opportunity, Xiaobian will give you a few!
Like wollastonite, it resembles the natural jade of Hetian jade, mainly including Dushan jade, jade jade, dense jade, Dongling jade, and Guizhou jade.
First, Dushan jade - look at the color
Dushan jade is one of the four major jade stones in China, but unlike Hetian jade, it is not a nephrite series, but a kind of petrochemical plagioclase, which is a multi-color jade. The color change of Dushan jade is very large, and the multi-color intertwined with each other is the biggest feature of Dushan jade. Some good quality Dushan jade can even be compared with jade!
Second, the jade jade - look at the color knife
Saitama is named after the place of production in Xiuyan County. Its scientific name is serpentinite. The main mineral component is serpentine, which is also not a nephrite series.
Regardless of hardness, or from texture, color, and luster, Saitama's gap with Hetian jade is more obvious. The hardness of white sapphire is low, water texture is often seen in the texture, and the gloss of the oil is weak; and the specific gravity of the white sapphire is small, and the performance is not strong, the transparency is large, the texture is uneven, and the impurities are more.
Third, Afghan jade - look at the glossy knife
Afghan jade has been active in the domestic jade market with the image of Hetian jade counterfeiters. However, due to its oiliness and gloss, it is comparable to other traditional Chinese stones such as Daiyu, Hetian jade and Dushan jade. The year attracts more and more attention from low-end and mid-end customers. Afghan jade is a carbonate jade, the main ingredient is calcite, so it is also called calcite jade. The hardness of Afghan jade is not high, and there are obvious scratches with a knife.
Fourth, Beijing white jade - look at the glossy knife
Jingbai jade is white in color and fine in texture. The color is pure white, flashing blue, flashing green, flashing gray, etc. Although the color is similar to white jade, it is definitely not as moist and delicate as white jade, which can be distinguished from glossy surface and hardness. In short, the identification of quartzite jade and Xinjiang white jade, observed with the naked eye, in addition to color, is mainly the difference in gloss, toughness, texture and so on. Quartzite jade is glass luster, brittle, often has uneven impurities, and has a poor moisturizing effect.
Five, glaze - look for bubbles to see the texture
Glass, commonly known as "feeder", is a kind of natural glass. In the market, the appearance rate of the imitation of Hetian jade is not low. Generally speaking, the color of the glass is in one go, there is no natural change, and most of the inside will have bubbles. At the same time, the pores of the glass are much thicker than that of Tian Yu, and the fracture is bright and shell-like.
