Mining and jewelry are suitable if one mining and one production are combined, because jewelry should be obtained from mines.
The most prominent problem of jewelry is to learn the formula, especially the formula of blue quality gems. The formula pricing in auction houses is arbitrary and high, while the varieties of blue quality gems in auction houses are often incomplete.
At present, the demand for gems is still relatively large, and the key is that your pricing should be reasonable. At present, the price of auction house is deadlocked, everyone wants to make money, and no one wants to reduce the price. A little lower will sell well.
If the gem market is not good, you can also sell ore or ingots directly. This market is generally stable, and you can always make money.
