One: look at the jade material:
Materials are the primary premise of jade collection, and high-quality jade materials are very important for a jade. At present, the usual price, the same level of jadeite is 6-8 times that of mountain material. In the market or online, it is more common to sell skinless mountain materials or Russian materials as fillers. Russian material is also a mountain material, and the material composition is the same. It is called Russian material because the ore is mined in Russia and the price is much lower. It is characterized by white color, but the jade is too watery, that is, the transparency is too heavy, and the density and oil texture are not as good as the authentic Hetian jade! It is difficult for people with little experience to tell if they sell rice in Russian. At present, there are only a few on the market or online.
Real suet jade, there is no national standard at present, produced in frozen glaciers. Sheep fat jade is as white as sheep fat, which is not only white but also never turns green. It has a high degree of grease and is comparable to jade with unusual mountain material or sheep fat color. Some old players have been playing with jade for decades. The difficulty in obtaining and rarity of suet jade makes it difficult for jade lovers to find it. It can be said that even if you have money now, you may not be able to buy exquisite suet jade.
Nowadays, most people who call themselves suet jade are Gaobaishan jade or Yayu jade, such as high white jade without skin. Jade workers all know that the price of jade is several times higher than that of mountain materials, so they must try their best to keep the skin when they work. It is often seen that some people try their best to burn fake skins in order to pretend to be Yu Zi. Whether jade without skin is jade depends on the experience and vision of the appraiser, so it is often controversial.
According to the same grade of Hetian jade, seed material is the most valuable, followed by landscape and mountain material.
Second, identify decorative patterns:
Modeling is the aesthetic framework of jade, and it is also an important factor to determine the collection value of jade. Modeling is determined by the function and shape of jade blank, and its proportion should be properly weighed. Symmetrical but not rigid, balanced and stable works are beautiful.
Pattern is the decoration of jade, and its beauty and ugliness are easy to be perceived and felt. Generally speaking, it is subject to the needs of equipment, or both depend on the needs of social functions. Decoration depends on the structure, composition, complexity and density. Where the structure is orderly, unity and harmony have appreciation value.
Third, art analysis:
Jade craft is the technical condition for turning materials into utensils, and its nature is relatively stable, so it is not easy to be truly recognized, which is a difficult problem in appreciation. Any neat, fluent and skilled craftsman must be beautiful or relatively beautiful. On the contrary, malaise and delicacy are the signs of a sharp decline in the collection value, which cannot be collected through trading. Art is the highest realm pursued by every jade, and it is also the most difficult to achieve. Everything with vivid charm and both form and spirit is the expression of artistic beauty, which embodies rich collection value. On the contrary, poor craftsmanship and poor art, blindly rubbing against the works of the ancients that violate the artistic beauty, the appreciation value is much inferior. Therefore, jade collection should not only pay attention to the material of jade, but also pay attention to the technical level and artistry of jade. There is a simple reason. The better the material of jadeite, the rarer its stock in nature, and the more difficult it is to process. The harder it is to make good jade, the higher its value.
