How to check the authenticity of jade certificates How to check the authenticity of jade certificates

1. Judging from the number. A genuine certificate has a clear number. If there is no number on the certificate, it is a forgery.

2. Judging from the English name logo. Genuine certificates generally have the marks "CAL, CMA, CNAL", and "CMA" must be present. If not, it means that the certificate is fake.

3. Judging from the signatures of the appraisers, a formal jade certificate requires at least two appraisers, so there must be at least two appraisers' signatures on the certificate.

4. Judging from the steel seal. There is a steel seal on the genuine certificate, and the fonts printed on the steel seal are clearly visible. If there is no steel seal, or the fonts are unclear, it is likely to be a forged certificate.
