How about studying jewelry appraisal in Shenzhen Senior Technical School?
My girlfriend graduated there, and she got all the certificates. She is also a jewelry major. She worked for two years 1500, and now she is bored every day. No, listen, the work place is Shenzhen. She said that her classmates seldom made jewelry after graduation. She said that the schools there are ok, but of course the fees are high. It depends on your choice. After graduation, your job will not be very high.
