The thing about the mines is that they're a guaranteed diamond source and the only thing you pay is time. (Aside from purchasing the mine itself, of course..)

If you have the patience, it really adds up. 5 big mines would be 20 a day, 140 a week, and 600/620 a month.

From what I see, the big mine returned today for an extremely short amount of time with no announcement. I can only assume that they accidentally put it back on the market.
