Kunming University of Science and Technology, Yunnan Vocational College of Land and Resources and Wuhan Jewelry College of China Geo University jointly held GIC jewelry appraiser course. There are three courses in this certificate: Emerald, Diamond and colored gems. I am a student of the National Land Institute. We all study and train during the holidays. Our school also recruits people who are not students of our school. You can find the telephone number of the jewelry and jade department on our school website for consultation. I remember that when we did the research and training, there were people from the society when we took the jade class, but diamonds and colorful treasures were gone. Because these two courses were more professional, I didn't understand them and felt it was unnecessary, so I didn't participate in the training. In this case, they can only get the certificate of jade appraisal course, not the certificate of appraiser. I studied the whole course at that time, about 14 thousand, and I don't know if there was any price increase. If you only study jade, it is about 3000.
