Well 3.2 also brings with it some new tasty gems. On my server the market is flooded and we can pick up epics for 200g, not too bad. May be a good time to buy some raw gems in preparation for all that phat loot.

Red
Runed Cardinal Ruby +23 Spell Power

Blue
Purified Dreadstone +12 Spell Power +10 Spirit

Yellow
Luminous Ametrine +12 Spell Power and +10 Intellect

This is a potential winner too for Tank healers who need more Crit
Potent Ametrine +12 Spell Power and +10 Critical Strike
