Because the evaluation of jadeite involves many aspects, such as raw materials, process quality, modeling and decoration, whether the theme selection is appropriate, artistic value and so on. The evaluation value of jadeite will also have a certain range of gaps. Jade has only been used for nearly 300 years in China, so its historical value and archaeological value are not high. In other words, jade products handed down in the Qing Dynasty have no obvious value advantage over jade works of the same time on the premise of the same texture and technology. In the jewelry industry, the price of jadeite is the same as other gems, but unlike gems, the price system of jadeite has not risen to the theoretical level, and it is more a reflection of the internal market of the industry. The main reason is that there is no internationally recognized quality evaluation system for jadeite evaluation, which is the biggest difference between jadeite evaluation and diamond evaluation. At present, domestic experts are deeply studying the value evaluation system of jadeite. 1. The quality of jadeite raw materials is the most important thing in jadeite value evaluation. Jade is the king of jade. The internationally recognized jade evaluation standard 4c2t 1v is introduced into the quality standard, aiming at jade raw materials. For an excellent jade work, the high quality of raw materials is the first to bear the brunt, which is also the most important item in the jade value evaluation. 2. The quality of jadeite craft. The collection of jadeite often refers to the collection of jadeite finished products, and there are few collections of original stones. Therefore, the creativity and technology of carving has become another important criterion to evaluate the quality of jadeite products. After a few months or even a whole year, a jade carving master has carefully carved the whimsy into fine products, which is naturally much more valuable than the small pendants sold in large quantities in the wholesale market. Ingenious sculptures are filled with ingenious ideas, and the green and moving beauty of emeralds can be fully displayed. 3. Choosing materials according to materials and using art are the basic requirements of jade carving. It is natural to cherish the precious jade raw materials, so there are many jade mountains, ornaments and playthings on the market, all of which are carved into conformal works, with the original intention of saving materials. According to the change of natural grain and color, the original jadeite stone is processed and made according to the trend, and the corresponding ornamentation is adopted to highlight the beauty of jadeite grain and show the beauty of humanistic carving. 4. The theme of jadeite jade carving is like the soul of jadeite finished product. According to the characteristics of raw materials, carry out the concept of careful and auspicious jade carving. 5. The artistic value of jadeite is the highest expression of jadeite collection. It is difficult for ordinary jadeite products to reach this level. Only high-end fine products have meaningful artistic value. For example, consider whether it is the work of a jade carving master, whether the creativity is innovative, whether special techniques are used, whether techniques such as pretty colors or color separation are used, whether the work has charm, whether the whole can surpass the predecessors and other factors. There are some subjective factors in the evaluation of artistic value, that is, different people have different views from time to time, but excellent works will always be recognized by most people.
