1, hetian jade is fine in texture. The so-called delicate texture is a sense of moisture. Good Hetian jade is moist as "coagulated fat", white jade is like sheep fat, such as lard, and topaz is like chicken oil.
2. The tiny cloud-like and cloud-like jade flowers are visible to the naked eye, which is the unique texture feature of Hetian jade.
3. Hetian jade has a mild luster. This is because there are very small bumps on the surface, similar to ground glass. You can see it with a magnifying glass of 10-20 times, so the reflection of light is not very strong. Hetian jade is "chiseled", like a refined man, with a gentle temperament and inherent talent, so it is moist-the word "moist" can best summarize the characteristics of Hetian jade, as the saying goes, "moist as jade", which represents the aesthetics handed down from China people.
4. "Strong and dense pulse" is not only reflected in the delicate appearance, but also an important standard is hard and not eating a knife. A real hetian jade, carved on its surface with ordinary tools, will not leave any scratches. On the contrary, hetian jade can not be easily carved with a knife. And it can scratch the glass without hurting itself. Observing the carvings, Hetian jade is not easy to crack when carving because of its strong toughness, while other jade is poor in toughness, fragile and easy to crack. Therefore, many quartzite jadeites are pressed out with molds at high temperature, and there are no traces of hand carving.
5, because of the "tight pulse", it is very heavy, and there is a heavy sense of oppression on the hand. Hetian jade is dense and delicate, moist and soft, oily and shiny, and heavy. These characteristics actually come from one thing: pulse combination. Because it is tight, it is heavy, so it is delicate and moist, so it is tough, so it is not very transparent.
6. Look at the color. Hetian jade is divided into white jade, topaz, sapphire, blue white jade, jasper and jet due to different colors. In the case of similar texture, topaz is the most expensive because of scarcity, followed by white jade, and sapphire, sapphire and jet are of lower value. Sheep fat jade refers to extremely white color, delicate texture and very expensive price. Many white jade is blue in white or gray in white.
7. Look at the skin. Hotan seeds often have skins. Looking at the skin has become an important basis for distinguishing seed materials. Now there are a large number of Hetian jade artificially dyed in leather color on the market. On the one hand, playing with leather is fashionable, on the other hand, it can also make people believe that it is seed material. This kind of processing mostly comes from Xinjiang and Henan. The basic differences between genuine leather and artificial dyed fake skin are: fake skin floats on the surface, with thin layer and bright color; The color of dermis permeates into it, with natural color and slightly concave and convex surface, which is called "pore" in the industry. It is difficult to distinguish between artificial dyeing and dyeing on hetian seed material with skin. Dyeing can strengthen skin color, make it more vivid and pleasing to the eye, and cover up defects at the same time. Some people dye the rolled Hetian mountain materials and pretend to be seed materials. Its characteristic is that it is rolled by a roller, so the whole is obviously smoother than the seed material, and there is no "pore" in the dyed skin, and the color obviously floats on the surface.
