Post here if you have an epic gem that's the wrong color and would like to swap with a guildie rather than sell it.
To start off, I have a couple of [item]Pyrestone[/item]s. PST me in game if you want one and have something to trade; I can use most all the other colors better I think.

(PS: I also have a ton of rares of all colors if anyone needs some cheap.)
I have some [item]Blood Garnet[/item]s that I can trade them with you for those :P but seriously, great idea GB:)
LF [item]Crimson Spinel[/item]s and [item]Empyrean Sapphire[/item]s, personally. All I have to trade are a few [item]Seaspray Emerald[/item]s, though. :(
Must I remind people to check out the Guild Bank?
