Best gems?

[GreenBunionSoup]

I'd like to know what gems are currently seen as the best. I know that there will always be things that are better in some situations, and that there isn't always a set best in things, but I just want to get a general feel for it. Right now I know the Diamonds are really good, Rubies and life drain Amethyst too. Any other good gems? I'm running a KFM, and want to know my options

In general attack power is easily the single best stat. Life drain is also very useful as is damage boost. I like stun (I've had it proc to stun half a room once on an AoE), but the cooldown timers limit it's usefulness. The stats matter more than the type per se.
