It doesn't matter whether the jade is true or false, as long as it is a certificate issued by a regular jewelry appraisal institution.

Consumer tips:

1. "National level" is just a general term and will not be used as the name of the institution.

2. Pay attention to whether there is any problem with the certificate. For example, abbreviations of national institutions usually begin with n. ..

3. If you are in doubt about the authenticity of the gold, silver and jewels in your opponent's hand, you can try not to follow the website address written on the certificate, but go to the company's official website for inquiry, or hand it over to the local quality inspection department for inspection.

4. After purchasing precious jewels and jade, go to the regular testing institution for re-inspection in time to minimize economic losses.
