1. The contact information of this institution must be printed on the certificate. On the back of the certificate, in addition to the qualifications of the institution, there must also be detailed information such as the name, contact number, address and website of the appraisal institution.
2. The qualification of the institution must be printed on the certificate. There are five kinds of institutional qualification certification: CAL certification, CMA certification, CNAL certification, CNAS certification and ICLA-MRA certification. The inspection report marked "CMA" can be used for product quality evaluation, results and judicial appraisal, and has legal effect. This symbol only indicates that the organization is a unit that has passed the measurement certification review and is a necessary qualification for any unit that issues a jewelry appraisal certificate.
The certificate must be signed by the inspector.
4. The appraisal content on the certificate is comprehensive and detailed.
5. The identification items on the certificate must be printed by the machine. The state forces the printing of identification certificates for machines, and the identification certificates filled in by hand have no reference value. If an appraisal certificate has the above five information, then the certificate is more authoritative.
