Look at the color discrimination. Teng Lang, a jewelry designer and artist, is currently the president of the Standing Council of Guangdong Miners Jewelry Association. Tenglang jadeite in the mine can be distinguished by color. Generally, the color of real jadeite is not so uniform. Emerald is a natural stone after all, and it is flawless. Real jadeite generally has uneven color distribution, cracks, and cracks will transmit light, which is generally shallow in terms of transmitted color. Fake jadeites are generally uniform in color. If there are cracks, it can be seen that there is artificial pigment deposition after light transmission, which leads to darker color.
