1.Se silver mine needs 15G+ (the cheapest) for both "Azeroth Diamond" and "Big Opal Stone".

2. Refined gold mine: absolutely the most profitable. First of all, those stones may be excellent (120g+); Secondly, the "shining glass" of jewelry processing has been changed to the possibility of producing epic gems (purple, I think the price is self-evident), so low-grade minerals made of refined gold and magic iron are loved by jewelry. Third, mineral processing will leave a pile of waste, but "fine gold powder" is white in nature, and its use can not be ignored: 4. Fine gold powder+1 native soil = refined mercury gold (mercury stone is needed for gold refining), and the price of refined mercury gold is generally 10G-20G each, depending on the region.

Second, cutting gems:

The cutter of 375 is not very profitable now (5- 10G), because people are basically reluctant to buy diamond (15g just changed one, but sold at least 300G/ piece). Maybe everyone will be willing to buy T5+ in the future. Earn 350 cuts-Stones with excellent cutting properties: 6 kinds of jade, red obsidian and dawn stone. However, these recipes are hard to get. Fell by the Mafia and Team 70 BOSS, his gem processing fee ranges from 8 to 8-20G. It is extremely rare that 100G is possible (unfortunately, the author does not have this blessing. The so-called extreme individual refers to increasing 15+ method damage, 26+ treatment, 12+ defense and 20+ attack strength. The cut direct sales are around 30-80, and the difficult 150 is also needed.

As for the gem of 375, the worship class and RAID achievement class all processed 20G+, the gem of 400G+ was cut, and the best one was 600+. The prices here are all reasonable and can be sold.
