If you find such a situation, you should negotiate with the merchant as soon as possible and exchange money or return it for free.

Jewelry and jade appraisal certificate must have steel seal or anti-counterfeiting mark. In order to prevent the certificate of the appraisal institution from being forged, the seal of the company must appear on the appraisal certificate. This seal must be clearly stamped and can be touched by hand. There is no steel seal, it must be a fake copy. In this case, you must contact the merchant for consultation at the first time.
