Made probably around 150k since MoP release. Just running the townlong steppes mining. i only run it for 5-8 hours twice a week (if that). i usually make over 1k at the vendor selling (cut) green quality gems each time. I sell the (uncut) blue quality gems in bulk steeply discounted from AH, and i never use the AH to sell more than a few gems at a time. Mostly sell to guildies. The off-color gems (i.e. orange, green, and purple) sell the best because they can be used to transmute Primal Diamonds. The red ones also sell well because they can be cut into "pure" stats (i.e. Agility, Strength, and Intellect). This process yields anywhere from 10-15k each time i do it. Hope this helped! Please like this if it did. Good luck and happy botting!
