What aspects of jade identification should be started? In the jade market, how many products, how to distinguish the real jade? Presumably this is also the topic that everyone is most concerned about. If you go to some jade market often, you must know some methods. The following small series will tell you from these points.
1. Color: White jade is often slightly blue in white, extremely white and pure white, and the glass is a kind of pure white and pure white. After the lamp is under the light, the glass is slightly orange.
2. Jade: One of the jade is warm and even, such as cream, but the lens is also radiant, but it feels exposed, but in the glory, it feels thief flashing.
3. Fracture: This is a distinct feature. The fracture of white jade is stone-like, dark and dull, jagged or jagged, while the fracture of the nitrate is characterized by material, bright and bright, shell-like. Although jewellery identification cannot be used for destructive testing, it can be observed by accidental bumps, non-glazed grinding surfaces and corners.
4. Impurities: There will be no air bubbles in the jade, but there are bubbles in the body. Sometimes it is not easy to be observed due to the translucent color, and sometimes the lens is of good quality and has very little air. However, as an identification, it is impossible to stop without finding a certificate. Sometimes we can check from the surface. If there is a trachoma, the performance of the bubble on the surface can also prove to be a nitrate. Because white jade does not have this feature, the internal bubbles can also be checked under strong light.
5. Specific gravity: The specific gravity of jade is between 2.9 and 3.1, and the nitrate is about 2.5. In contrast, the nitrate should be lighter. 6. Sound: The sound of jade is dignified, and the sound of the glass is crisp. In some cases, it can be identified by the light of the jade and the light.
Through the above points, you can basically identify the true and false of jade. I hope that the above knowledge can be applied to real life and help you.
