At present, the two most authoritative appraisal institutions in Hefei are Hefei Mineral Resources Supervision and Inspection Center of the Ministry of Land and Resources (No.239 Wuhu Road) and Anhui Gold, Silver, Jewelry and Jade Quality Supervision and Inspection Station.
There is no national inspection in Huaibei. You can also go to the local geological bureau for testing.
I hope the answer can help you.
