Jewelry processing also does not require a certificate.

Certificates are all appraised and there are many kinds.

Tell me what I took in the exam for your reference.

The training period of China Gemstone Association Gemstone Appraiser Qualification Certificate (GAC) is about one month, and the cost is about 2000 yuan. But there seems to be some other requirements, which I forgot.

The training time of Hainan intermediate gem inspector qualification certificate is less than one month, and the cost is less than 1 10,000, but it is useless.

It costs about 3,000 yuan to train the diamond grader's qualification certificate for more than one month.

The qualification certificate of intermediate diamond inspector is tested together with the above training, that is, you can get the certificate for several hundred yuan.

Others are.

The cost of GIA is around 5000 yuan. Want to take an examination of the most authoritative high school in China, need 5 years of relevant work experience.

It's hard to say the cost of the national jewelry and jade appraiser's qualification certificate, because you have to get the above certificate first, and then you have to take the legal and economic registration exam. If you have a high school education, you must have 7 years of work experience.
