The following answer is unreliable. CGC is a qualification certificate, and you must work in related industries for a certain number of years before you can take the exam. . The first requirement is a degree with corresponding major and work-related years. Or the second condition is to pass the advanced appraisal exam, such as FGA of Geological University. . Basically, this is the certificate with the highest gold content in jewelry appraisal industry. It is tested once every two years and registered nationwide. . Freshmen don't like CGC. .

NGTC is much easier. You can search the website of the National Inspection Center. His family has training courses in various regions, which cost several thousand yuan. He has been studying full-time for 8- 15 days, and the passing rate is still very high. . After passing the examination, NGTC certificate will be issued, and Grade IV (intermediate) certificate of professional qualification of the Ministry of Labor will be issued. .

In short, these two certificates are not of the same difficulty level. . Just take one exam and you'll make a fortune, and the other one will go up in the high-end atmosphere. .
