Experienced insiders can look at the quality of jade through the lightness of Hetian jade, because by looking at Hetian jade, you can see some impurities and flaws in jade with the naked eye. Although it sounds simple, it must be passed through Hetian Yu. The quality of light detection jade still needs technical content. We must look at the internal structure of Hetian jade by lighting. The angle of lighting is also very important. We must observe the light from a short distance to a long distance. It is necessary to pay attention to whether there is flaw in the dark, and the finer the internal jade is, the higher the quality. Here, we must also remind you that you must use ordinary flashlights when conducting Hetian jade light transmission. Some high-quality dimming flashlights are likely to have light problems and identify the quality of Hetian jade. When lighting, properly adjust the angle and distance of the flashlight, and pay attention to the light is not too strong. There are also many deep-colored Hetian jade varieties in addition to the side to be hit in the light, but also from the profile to the original distance of light, to see if its structure is uniform, there is no sugar color and so on.
