This mine was recently discovered as an almost breeding ground for all kinds of precious gems. Any kind of diamond, emerald, ruby, or whatever you can think of can be found here. This is more regulated, and most cannot get in without some kind of status or can show they are a jeweler of some sort. Though you can pay for raw materials to be mined for you at a desk inside. Things can be made a lot cheaper that way if you provide materials. Hint.
