The net result of Blizzard's grossly inflated gem economy is that the only type of gem that's worth socketing in an item is a flawless square (with the possible exception of a perfect square amethyst in a weapon for LoH). The rock-bottom commodity prices on the AH make anything lower than flawless square worthless trash. And if you have enough gold to afford a higher level gem, you can get a much better return on your investment by shopping AH for a gear upgrade.
