In the jade market, there are often some jade jade mixed into some exquisite artificial jade. Therefore, everyone is most concerned about the identification method of jade. This relationship has an important role in not being deceived by jade merchants in the future. The reliable method of identification is: watching, listening, and testing. Look, mainly look at crystal transparency, true jade transparency, grease gloss; listen, true jade sound is crisp, and vice versa; test, true jade from the glass, leaving scratches on the glass, and jade itself is not damaged.
Common fake jade has different fake methods such as plastic, colored glass, marble (marble), electric color fake jade, jade powder and crystal and salt water, and other methods of identification. different. The texture of the plastic is lighter than jade, and the hardness is poor. It is generally easy to identify. Coloring off work is also easy to distinguish. As long as you get the light or the sun, you will see a lot of bubbles in the glass. More difficult to distinguish is the electric color fake jade, which is designed to be plated with a beautiful emerald appearance on the inferior jade, which is easy to mistakenly think it is true jade. At this time, you need to observe carefully. If there are some small cracks in the green with blue, it is fake jade. Because it will leave cracks when electroplating, experts call it "spider claws." It has also been said that when the electrochromic jade is placed in the hot oil, the electroplating color will subside and it will be its original appearance. Synthetic jade made of jade powder, crystal and salt water is imitation of dark old pit jade. The method of identification is simple, that is, their specific gravity is different. The natural jade has a specific gravity of 3.3-3.4, while the synthetic jade has a specific gravity of only 2.8. You can tell the difference between the hand and the weight, or use the balance to weigh the true and false. The jade that is imitation with the nitrates looks better than the jade. The ancients said: "Jade match nitrate, must be high." That is, white jade is like a glass, it is considered advanced. It can be seen that the nitrates and jade are difficult to distinguish. However, true and false are different after all. As far as color is concerned, the white color of white jade is often blue, and there are very few white ones. The glass is pure white with even whiteness. As far as jade is concerned, jade is moist and delicate, such as fat as a paste, although the nitrate is also warm, but there is inevitably a thief in the radiance. White jade is a natural product, and it is difficult to make all the body uniform and uniform, such as jade gluten and jade flower. If the nitrate is made by hand, there is no such appearance. The white jade has a solid texture and no bubbles are available. The processing of the glass is good, and there are often bubbles and exposed eyes. Knowing these items will not make the glass products a jade.
To identify the quality of jade, according to jade color, jade, jade and so on. Whether it is white jade, topaz, sapphire or jasper, its jade color must be clear, and it is best if it is not evil or gray. In terms of jade and jade, it is required to be fine and white, pure and without impurities. No matter what color of jade, the finer the quality, the better, the finer the more moist. Jade is made of jewellery and is suitable for people of all personalities and ages. Whether it is a beautiful young girl, or a young woman with a rich rhythm, wearing a string of sparkling diamond necklaces, and wearing a pure crystal jade earrings or bracelets, will look radiant. Identify jade, mainly to prevent the use of nitrate as a white jade. Identification can be done in terms of color, jade, fracture, impurities, specific gravity and sound.
