1. Submit for inspection: The first step in making jadeite certificate is to submit for inspection, bring valid identity documents to the testing center, and go through the inspection procedures in the "Personal Entrustment Inspection Window" of the testing center. The business personnel here will handle the relevant inspection procedures for the samples that meet the inspection scope for you. After the inspection is completed, you will get an entrustment contract. With this contract and valid identity documents, you can get the certificate and send the inspection samples within the specified time. Finally, the jadeite to be identified is put into a container and sent to the sample management room for testing together with the task list.

2. Testing: After the jadeite is sent to the sample management room, the administrator of the testing center will make a file for jadeite, and then assign it to the person in charge of testing for testing. After each test step, the results will be filled in the file. In order to ensure the accuracy of detection, each jadeite will go through three procedures: initial inspection, re-inspection and general inspection.

3. Initial inspection: The initial inspection consists of "gem inspection" and "precious metal inspection". If the jadeite you send is inlaid with metal, you need to test the gems and precious metals. Precious metal detection needs to detect the imprint of precious metals (whether the manufacturer and metal imprint are complete), and then it needs to carry out nondestructive testing of precious metals. If it is still uncertain, it is necessary to carry out chemical analysis and testing of precious metals. If there is no inlay, only gem testing is needed. Gem testing is conducted by two experienced jewelry appraisers. If there is more than one gem embedded in jade, it should be tested one by one.

4. Audit: Gems and precious metals should be sent to the audit bureau for audit after the initial inspection, and can only be sent to the general audit after passing the inspection.

5. General Audit: The General Audit Office will audit all test results. After the general examination and approval, Emerald will be sent back to the previous management room, and then the certificate will be issued.

6. Certificate issuance: When making the certificate, the jade will be reviewed and photographed again, and then all the data obtained will be summarized and the photos of the jade will be printed on the certificate. The certificate must also pass; Verification, stamping, anti-counterfeiting identification, plastic packaging and other procedures. After all the formalities are completed, a jade certificate is born. After the certificate is completed, it will be sent to the business room to wait for the owner to pick it up.

7. Certification: Certification is very complicated. It takes about nine procedures to get a diamond ring, from inspection to inspection, plus various audits in the later period, and finally it takes about thirteen procedures to get a certificate.
