Hello, you should be talking about the certificate of jewelry appraiser. There are two kinds. One is assisted by the shopping mall, which means that you are an employee of this shopping mall and have more than one year's experience in jewelry or jade counters (the specific years vary from shopping mall to shopping mall). Shopping malls will handle this card for you out of their own competitive advantages, and others will handle it themselves. You can find local jewelry or related associations to handle it. At present, such certificates are mostly issued in the form of associations. This has little to do with academic qualifications, but mainly work experience. Good luck!
