After understanding the classification of Hetian Moyu, there are friends who like to go to the collection and purchase, but now the market is chaotic, so also pay attention, then how to distinguish between the true and false of Hetian Moyu? There are too many black jade, there are jade and ordinary stones. They are the same as the naked ones. The composition, nature and material are very different. The price is also very different, so it is still necessary to distinguish. First of all, let's see what are black jade? There are three kinds of black jade, ink jade, ink jasper, black sapphire. Although they are all black, there are obvious differences that cannot be confused. Moyu Although the jade is formed by graphite immersed in white jade, but under the naked eye, the base of white jade is completely invisible. Only when it is hit with a glare, it will see a white halo, and because of poor light transmission, general halo Very small, about 2 mm. Mobiyu Ink, it is also black. In the general daylight, Mobi sees the lacquer black with the naked eye. If it is illuminated with strong light, it will pass through the green light, because the essence of Mobi is jasper. The value of jasper itself is large, and if it is a boutique, the value is extremely high. Black sapphire Black sapphire looks green in the black under natural sunlight, and looks black when it is cloudy or when the light is bad. Basically, it does not see green. The characteristics of black sapphire are very light, and it is yellowish green under the strong light. Moxi jade counterfeit goods In addition to the above-mentioned ink jade and black sapphire that are easily confused with the ink jade, there is an ordinary black stone kava stone, which is even more worthless, but it is used to make fake jade and jade. The biggest difference between black kava and ink jade is that it is opaque and not oily at all. It can also be identified by a magnet, because the black kava stone has a large iron content and can adsorb the magnet, but some black kava stones do not absorb the magnet, and it is better to use a strong light irradiation and a magnet to identify one by one. To sum it up, we use a strong flashlight to illuminate: If it is a jade, it should be white; If it is ink jasper, it should be green; If it is black sapphire, it should be yellowish green; If it is black kava stone, the light transmission is disorderly or opaque; If it is opaque, it is either kava stone or other stones.
