At present, the fees charged by quality inspection institutions around the country for issuing appraisal certificates for jewelry and jade are different. Even in the same city, such as Shenzhen, there are many qualified institutions that issue appraisal certificates, and the fees are different.

Generally, the diamond certificate is 50-80 yuan/piece, while other gems (such as rubies and sapphires) will be slightly lower. Jade or other jade is generally 20-40 yuan/block. When the number of documents submitted for inspection is large, each document can be reduced by several yuan through negotiation.

Therefore, the manufacturer said that a certificate is "worth 200 yuan", which is obviously fooling you!
