The most authoritative training course in China is the national jewelry and jade quality inspector training course offered by the State Inspection. It is the best and most comprehensive, but the cost is not cheap, it costs more than 20,000 yuan, and the registration qualification is also very strict. There are also small training courses in the national inspection, ranging from three to four thousand, but the certificates obtained are relatively not very authoritative and the awareness is not very high.

Secondly, China Geo University (Beijing, Wuhan) has set up a training course on jewelry and jade identification, with good teachers, many of whom are national masters, old experts and old professors. But there is no certificate after training, only the corresponding certificate. The advantage is that you can really learn a lot.

Finally, the training courses provided by small training schools, half of which are very commercial and come for making money. It is recommended not to go.
