Well, Fortune III is a very high level enchantment - so, you need at least an Enchanting Table (2 diamonds), A diamond Pickaxe, 30+ levels and luck (not necessary you will get Fortune).

Then there is the added load of finding diamonds in the first place. I have been strip mining at Y = 16 and Y = 12 for almost 15 in-game days now and I have only found 19 diamonds.

Sure, once you do ge Fortune this method is going to be redundant but this tip is for those who would like to beat the record for finishing the game or would just like to get diamonds relatively easily.
