The appraisal certificate of jewelry is by no means a means of sales. Just like each of our ID cards. The certificate is the identity card of the jewelry. Just remember, the certificate issued by the jewelry inspection station can't be false. The lowest municipal level, then the provincial level, of course, the domestic inspection is the most authoritative. And foreign certificates. This is a long story. As for online fraud, it is generally not, and I have never heard of fake websites with detection stations.

Give you a jewelry common sense!
