GIC has training centers all over the country. You can register for diamond appraisal and gem appraisal in the training center. After passing these two courses, you will get the corresponding certificate. These two certificates can be exchanged for GIC jewelry appraiser certificates. Conduct training and assessment at each training point, and then certify after passing the qualification. You don't need to go to the big registration. You can search the website of Dazhu College for training information, and choose the nearest place to attend training and study. The website has the contact information and training time plan of each point. Just contact the teacher, and the teacher will tell you when to train.
