Foreign countries are better, such as GIA's G.G., FGA and HRD. The application conditions are relatively simple and the price will be much higher. GIA's two certificates (diamond appraisal and colorful treasure appraisal) have been taken down for almost 60,000 to 70,000. FGA, the tuition is about 20 thousand to 30 thousand.
If you want to go abroad to make a living, it is recommended to take a foreign certificate. If you are in China, it is enough to go directly to CGC. Of course, if you feel that you don't have the strength or can't meet the requirements, you can apply for some simple certificates first, such as diamond inspector, gem inspector and jewelry salesman in the Ministry of Labor Protection.
