Individual jadeites are inspected (or approved) by Caibai, Xisiyang Hutong, Liuliqiao Lotus Bao Tong, Xiaoying Beijing International Jewelry City, Xinjiekou Guangjin Avenue Jewelry City, Wuhuan Jewelry, Huafu Xinyang Jewelry, Wante Jewelry and Dazhong Temple Ai Jia Collection, all of which can identify jadeites.

It is unrealistic that no organization can issue the certificate of origin. For example, gold alloy testing tells you that the purity of gold is the purpose, so how do you judge where the mine is? . Without this ability, the jade appraisal institution can not only give the place of origin, but also give the price judgment, which is impossible.
