For ordinary people, in the mixed market of Hetian jade, it is more difficult to choose the real Hetian jade. Therefore, when purchasing Hetian Qingyu, the method of identification of Hetian Qingyu should pay attention to the following points: Look at the certificate issued by the national professional testing agency. The formal appraisal certificate will clearly indicate the name of the appraisal institution, the type of gemstone, the weight of the appraisal and the way of inquiring about the institution; the large block and the field jade must have texture and spots, and each side The textures and spots are different, because jade is formed after tens of thousands of years, just like the fingerprints of each of us, it will never be the same; many people think that jade should be transparent, but it is not correct. Really transparent is only a small piece of jade, the jade block will not be transparent once it becomes larger, but as long as it shines under strong light, it will show its transparency. Therefore, the bigger and darker it is, the bigger the black, the bigger the more Rare, the bigger the more valuable. The main mineral component of Hetian Qingyu is tremolite. The texture of jade white jade is very similar, but its quality is slightly worse than white jade. Because the price of Hetian Qingyu is cheaper than white jade, and the block size is relatively large, it has been particularly popular in the market in recent years. Whether it is collecting sapphire or purchasing sapphire jewelry, it is especially important for its identification. Method of identification of Hetian Qingyu: Method 1: Look at the grain: The internal structure of the sapphire is very clear, and the stone can be clearly seen with the naked eye, and the sapphire also contains a lot of impurities. The pseudo-sapphire can imitate this kind of texture, but it gives the impression that it is like painting. It floats on the jade table and is extremely unnatural. Method 2: Look at the gloss: The texture of the sapphire is very delicate, waxy, warm and soft, but the imitation sapphire is usually lighter, and it is glassy and has a poor moist feeling. Method 3: Look at the price: Although the jade is not as precious as the white jade, its price is not the price of dozens of hundred grams of cabbage. As a variety of Hetian jade, the jade is especially precious, so if you encounter a very cheap sapphire, then it must be Counterfeit.
