I have tried that place aswell.. small circles at the edge of the big circle. the 2 outer ones, gives no bonus, only 1-2 diamonds.. the next two gives 1-4 and the center one gives 1-8, making it the only one worth mining in. And i belive all bonuses has been turned of for diamonds in Dresden, and the sell price at The ring in New Berlin is 2500 now.
But to show the ones with the best yield, just look at it as this:
3 2 1 2 3
One being the place you want to be.
Though while the price for diamonds has been lowered in The Ring in New Berlin, then it has been raised in New Tokyo at Narita it seems. They pay 10.500 for each.
Me and my friends did quite a bit of research last night, and got all the new prices for what the different mined commodities sells for, and none matches the ones on the wikia or forum, except scrap metal in Omicron Gamma, and Toxic Waste i belive it was.
I had verified the 1 2 3 part myself and from it extrapolated the 3 2, thanks for confirming my assumption

Information, the first principle of warfare, must form the foundation of all your efforts. Know, of course, thine enemy. But in knowing him do not forget above all to know thyself. The commander who embraces this totality of battle shall win even with inferior force.
