MMO Champion: Shaani the jewelcrafter is now selling epic gems previously only dropped in 25-man dungeons for 15 badges apiece, and all the recipes to cut them for gold at various levels of Shattered Sun Offensive Reputation. So if you don't raid, and don't mind doing 3 or 4 heroic runs for each gem, you'll be able to socket all that new badge gear too. It looks like it was unlocked with the Razorthorn Root daily, so if you want those gems, be sure to get your friends and guildies on doing that daily once it's unlocked on your server come 2.4
While you're there, you can also grab a new daily from Mar'nah the alchemist which will reward a Bloodberry Elixir, which provides +15 to all stats for an 2 hours, but only on the Sunwell Plateau itself (thanks for catching the Sunwell-only restriction, Aikiwoce).
The badgification of epic gear continues apace. What will be interesting to see is if Blizzard is primarily doing this to close the gear gap between casuals and raiders for WoTLK, or if this marks a new loot philosophy that will continue into WoTLK. Will we be able to buy Icecrown Glacier gems for badges as well?
