Looking at the jade certificate mainly depends on the description of the jade identification elements. Such as certificate number, inspection conclusion, jadeite gram weight, size, refractive index, density, amplification inspection, etc.

First of all, the appearance depends on whether the jade photo on the jade identification certificate is consistent with the real thing, and it should be observed from the aspects of workmanship and color. (Jade bracelets should also be checked for cracks). Total mass This is the weight of jadeite, which must be consistent with the certificate.

There are several points to understand the certificate: look at the appraisal conclusion: the conclusion of the appraisal certificate must be standardized.

Certificates should be in one-to-one correspondence, that is, a thing is a certificate, and the certificate should have pictures and weights of the goods. Although some things come from a piece of raw material and look similar in appearance, jade ornaments are not exactly the same. One thing with a certificate can't prove the quality of the whole batch of things.

Certificate background content. When the pictures and data on the jade appraisal certificate are completely consistent with the real thing, we should also pay attention to the authenticity of some background contents appearing on the jade appraisal certificate.

Look carefully at whether the shop opening organization that issued the inspection certificate of jadeite jewelry has the right to issue the jadeite appraisal certificate.
