@raze: yup, that list is still good. Add
3 to 4 in the aleroth market from gem dealer and also drop exploit shaver posted which means any quest capable of spawning a gem as a reward can drop up to 5 and also Halliwells chest always spawns his locket and 1 malachite as a set drop
As for the time, you'll probably be talking a good 60+ for DKS with the replay factor adding more than enough time on it to make it a good purchase
