When consumers buy jewelry, precious metals and jade articles, what they are most worried about is quality and authenticity. Jewelry appraisal certificates are just like their "identity cards". It feels more practical to have jewelry appraisal certificates, but there are also cases where jewelry appraisal certificates are forged, so it is also important to learn to distinguish the anti-counterfeiting of certificates.

At present, there are many institutions providing jewelry appraisal, among which the most authoritative is the National Jewelry and Jade Quality Supervision and Inspection Center. Let's take the National Inspection Center as an example to see the steps of jewelry appraisal:

First, check

When sending for inspection, it is necessary to bring valid identity documents to the inspection window of the testing center to go through the inspection procedures for jewelry that needs to be identified. Here, the business personnel will go through the relevant testing procedures for the samples that meet the testing scope. Then you will get an entrustment contract, with which you can receive the certificate and send the sample for inspection within the specified time. After that, the jewelry to be identified will be put into the inspection container and sent to the sample management room for inspection together with the task list.

Second, detection.

After the jewelry sent for inspection is sent to the sample management room, the sample administrator will create a file for this jewelry and distribute it to the inspectors for testing. The inspector will fill in the documents according to the test results of each step.

Third, preliminary inspection.

The initial inspection includes two parts, one is gem inspection, and the other is precious metal inspection. If the jewelry submitted for inspection is inlaid jewelry, it needs to be tested separately for precious stones and precious metals. If the jewelry submitted for inspection is not inlaid with metal, then only gem testing is needed.

Fourth, auditing.

After the initial inspection, the results of gemstone inspection and precious metal inspection should be sent to their respective audit offices, which will be inspected and audited by special personnel, and then sent to the general audit after passing the examination.

Verb (abbreviation of verb) general audit

The staff of the chief auditor will comprehensively review all test results. After the final review, the jewelry was sent back to the sample management room.

Issuing the certificate of intransitive verbs

In the certificate department, the jewelry will be weighed again, inspected and photographed. The obtained data and photos are printed on the identification certificate together with the detection data obtained in the previous detection process. After verification, stamping, anti-counterfeiting identification, plastic packaging and other procedures. A jewelry appraisal certificate was born. Finally, send the samples and test certificates to the business office for consumers to collect.
