is it just me or does the fortune pick not seem to be working on diamond. Hard to tell if its working on coal/redstone but found my first diamonds while starting my mine shaft and it gave me 1 ea with a fortune 3 pick.
I have fortune on my pickaxe and I can say 100% that it works on diamond and any other ores. Hybridohio, I believe what you are experiencing is actually just bad luck. The fortune enchant gives you a higher chance to get more drops out of an ore not a 100% to get > 2 out of an ore.
