The "species" of jadeite is also called "species", which refers to the size of crystal grains. The smaller the crystal particles, the better the species, the larger the crystal particles, the worse the species. It is roughly divided into old species, new species, new and old species, and Ouyang Qiumei divides it into: old pit species, dark green species, iron dragon species, tortuous species, loofah green species, sika deer species, hibiscus species, bean varieties, Glass, ice, oil, green, thunder, green, gold, green, white, green, eighty-three, eighty-two, kada There are 26 kinds of purple sapphire, black-bone chicken, red jade, topaz, Fulu Shou, dry green, and ink green (a large variety of glass and ice). "Water" is also called "water head", which refers to the transparency of jadeite, that is, the transparency of jadeite. Experts will use one to three centimeters of water, gradually increasing from low to high transparency, the third is the most transparent, and the glass is three. Divide water. Another commonly used noun is "bottom", and some connoisseurs are called "bottom water" and "bottom sheet". In fact, they are all about the transparency of jadeite. It is the size of jadeite crystal particles and the fine structure of jadeite felt structure. The degree of determination, the smaller the crystal particles, the denser the felt structure, the higher the transparency of the jade, the better the water. When judging the water of jadeite, we mainly rely on experience to make judgments. In addition to careful observation, we can also use contrasting means. Using a jade that we are familiar with, compared with the jadeite to be judged, we can quickly find that the water is bad. Conclusion. So how do you judge the water of jadeite? What problems do we need to pay attention to when judging the water? In the comparison, we should pay attention to the following issues: First, pay attention to the interference of other external substances. Clean the jadeite first, and pay attention to the surface with no oil residue. Because some jadeite is not good for water, in order to improve its performance level, it is often immersed in oil. Wait until someone is ready to buy it, and then take it out. If it is such a thing, the score on the water judgment is to greatly reduce the score. There is wax, the surface coated paraffin will also improve the performance of the water. Second, we must pay attention to the same kind of light for comparison. If the light is different, the refracted light we see is definitely different. The light is different, and the light is transmitted inside the jade. The situation is completely different. Therefore, pay attention to the intensity of light. , the angle of the light and the hue of the light. Thirdly, we should note that the plain surface, especially the jadeite of the curved surface, their surface gloss, in the case of the same kind of water, is better than the carved jade. Especially the jadeite with good water, in the case of curved surface, It can receive light well, so that the externally injected light will not refract in the jade, and will spread again to form a crystal clear scene. People often call it fluorescent. To achieve this kind of situation, it can also be said that the essence of jade is interpreted. Full of dripping.
