a hint for newbies trying to find new resources. on aquatic and terrestrial maps you can actually go beyond what is "safe" if you stock up on minerals and recycle for health as you need. it makes it a lot easier.
deth, ive gotten 3 gems in a row before. it is really down to luck. usually when i want gems i go to hardest rock i can one hit and then rapidly click that till i get the gems i want.
Fixed!
