1. Look at the luster of jadeite: Different jadeites have different refractive indexes, which leads to great differences in the luster of jadeite. Although there are some impurities and patterns on the surface of natural jade, it is normal to have obvious luster. The surface luster of fake jade is dim, and the whole jade looks dull, giving people a dull feeling. 2. Look at the color of jade: Most fake jade is fake in color. Then, if you want to distinguish the true and false jade, you can observe it carefully with a magnifying glass. The true color of jadeite varies in shades, and the color distribution is irregular. The color of fake jade is mostly bright and dripping, and the color distribution is more uniform. The color transition looks unnatural.
