I gotta say one thing about your prices. I've been watching the auction house since the game launched and level 20 legendary gems don't sell for anywhere near what you have them at. In fact the protection and assault gems sit unclaimed all day at 35k-40k, and the prices are going way down. I've seen them up for as little as 15k just yesterday. All in all a good guide though for at least showing where the different gems drop.
