The colorful jade in Yunnan is lifelike. As a well-known brand store selling jadeite, every jadeite sold has an appraisal certificate issued by an authoritative jewelry and jade appraisal institution with national qualification certification.
Tao Tao can still do it if he can understand things, but now the jade is too deep, most small businesses are mixed, and there are too many pickling and dyeing. To be on the safe side, it is best to choose a big brand, at least it will not disappear overnight. Guaranteed. I hope I can help you.
