The type of jade refers to the quality of its intrinsic texture, which is reflected by the fineness, density, transparency and hardness of the flesh. In other words, the finer, denser, more transparent and harder the jade is, the better the quality of the jade will be, and vice versa. Among various jade and gemstones, only jadeite introduces the concept of "species", while other types of jade and gemstones do not have the concept of species. Why is tender jade unpopular? The "types" of jade are also very varied and complex. Different jades have different types, and the difference between good and bad is also very large. The difference between good and bad jade can be distinguished by "old kind" and "young kind". Old kind of jade refers to jade with good texture, and young kind of jade refers to jade with poor texture. The most prominent feature of tender jade is that its structure is loose and not very dense, which means that its cutting or polishing surface will be very rough, and will have many star spots, or fly wings. Why is tender jade unpopular? Among the tender types of jade, there is one that is the most deadly, and that is tender and hollow jade. The tender hollow jade has good water content and delicate texture, but it has a fatal weakness: it is too tender. Although its skin is very thin and has good light transmittance, its texture is loose and worthless. It is sold as kilogram material in the jade market. Why is tender jade unpopular? The reason why tender and hollow jade is tender is that its structure is relatively loose, its density is poor, and its density is also very low. Generally speaking, the gaps between the jadeite crystals are relatively large. Therefore, the appearance of tender hollow jade looks very beautiful, but in the actual processing process, due to its low hardness, it is difficult to carve it finely and it is also difficult to polish it to a shine. People in the industry call it "not receiving light" or "poor quality". Moreover, even if the tender and hollow jade is processed into a finished product, it will become dry over time. Due to the lack of moisture, its color will become lighter and lighter, that is, the color will fade and fly away. It will slowly become uglier and uglier. Therefore, the value of the tender and hollow jade is naturally not high, and it is not favored by jade experts. But even if experts don't like it, there are others who do, and they are the people who make B-goods and C-goods. The tender brick materials are the raw materials for their processing and production. Why is tender jade unpopular? So, in the process of gambling on jadeite, how do you identify the quality of jadeite raw stones? We can observe and analyze the gambling stone through the skin and fog characteristics combined with the window. The skin of tender jadeite will be thicker and the fog layer will also be thicker, which usually appears in jade materials with black gauze skin and black fog. Why is tender jade unpopular? This is because during the later transformation of the jadeite raw stone by surface geological actions, the thick skin and thick fog of the raw stone blocked the further penetration of minerals into the interior of the jadeite, making it difficult to form secondary mineral deposits in the crystal gaps of the jadeite. The interior of the jade cannot be filled and compact, so its density will be poor, and its quality will naturally be poor as well. At the same time, because there is no infiltration of minerals, the jade maintains its original purity and appears very clean on the surface, thus concealing its tenderness.
