There is no diamond re-inspection in Quanzhou, but there is one in Fuzhou. The specific address is as follows:

Provincial Gemstone Quality Inspection Station (No.97, Hongshan Bridge), Provincial Gold and Silver Quality Inspection Station (No.306, Block B, Minhui Building, Dongjiekou Scenic Resort Scenic Area), and Fuzhou Daixin Jewelry Testing Agency (5th Floor, Liuyi Middle Road Characteristic Art City).

Generally speaking, the cost of diamonds in 300 yuan has a unified international appraisal standard. However, the inspection methods and standards of overseas institutions and laboratories are not uniform. There may be cases where diamonds with VVS 1 grade have IF grade certificates and IF grade prices.
