First off before I introduce the texturepack, yes this only changes one thing in the 12w21a Snapshot and it should only be used for that snapshot or it will do absolutely nothing. What exactly this will change is that when making the extremely rare Emerald Ore, Jeb got the texture wrong by accident, and I know some people are picky about this. I would also like to ask you to refrain from making comments such as "This only changes one thing and shouldn't be counted as a texturepack because anyone could do it." I ask this not to be commented because some people don't know how to edit the look of their game, and because I am making no money off of this because I'm not using Adf.ly, and I may add on to it in a little while.
Now, on to the pack.
This is the original texture of the ore found in its natural habitat of level 16 near lava level, and in the Extreme Hills biome:
And this is the edited version with the correct texture:
