1. Authentication of certificate: 1. There is a security label in the upper right corner, 2. There is a steel seal on the certificate. If these are all available, the certificate is basically no problem.

2. Emerald A is a business statement. In the appraisal, the appraisal result is: jade. It is the corresponding commercial A goods. If the appraisal result is: jade (treatment). Then it corresponds to commodity b or C.

Beijing Gem Testing Center is affiliated to China Geo University. This is a nationally certified laboratory. No problem.

4. If the identification result is jadeite, then the refractive index, polarization, specific gravity and magnification of this article are all within a fixed range, and it is not necessary to indicate them one by one.
