Jewelry design is an art undergraduate, which requires a good foundation in art. Gemstone material technology has some engineering courses, which belong to the College of Materials Science and Engineering, and some science courses, which belong to the specialty of mineral and rock deposits in geology. There are basically only one or two majors in domestic geological colleges, and there are also jewelry and marketing majors in university education. I graduated from Jewelry College of China Geo University. As an undergraduate, I can learn some principles and industry foundations of jewelry appraisal. However, if I really want to be an excellent appraiser, I need to engage in this kind of industry, accumulate years of experience and exercise my eyes, hands and heart. Take the national jewelry appraiser exam. Basically, if you look at the personal experiences of teachers in universities, you will know the way to become an expert. If you want to do jewelry trading, you can contact your former brothers and sisters more. Excellent universities in China include China Geo University (Wuhan) and China Geo University (Beijing).
