Right, it's raid reset time, 4.0.3a has landed and most dps classes have found out that their cherished Chaotic Skyflare Diamond has had it's requirements changed to something completely ridiculous.
This may well be common sense, so flame me if you like, but there is a massive demand for the following gems from raiding dps classes...
Melee/Hunters are going for Thundering Skyflare Diamond
And casters are taking either of the following, Tireless Skyflare Diamond
Insightful Earthsiege Diamond
or Ember Skyflare Diamond
So jewelcrafters get crafting, alchemists get transmuting (Transmute: Skyflare Diamond) and make some good money while the rush is on!
