If you want to make jewelry quickly, you can only auction the materials by yourself (the ore is decomposed by yourself, and the jewelry materials are counted), but in this case, it may take 5000-6000G to make it to 525. Maybe I said less.

But if you want to sell money with jewels, the money you spend will not be directly proportional to the jewels you sell in a short time. If you want to practice for your own use, I recommend that you learn mining and jewelry and practice slowly by yourself. At the same time, you can go to the auction house to sell the remaining jewels for free.
