Jewelry processing needs to extract minerals from ores. If you major in mining, you can be self-sufficient. You can choose one out of every five ores, and randomly produce green quality gems, which may produce excellent ones. If it is not mining, you can go to the auction house to collect ore or collect gems directly. The specific price is based on the price of each server. In addition, every time you hit the dragon soul (non-random group), each BOSS will drop a crystal cluster, which can be used to exchange an item at the bottom of Longmian Temple in the copy, and you can also open gems every time. I hope I can help you.
