Patch 4.0.6 - New meta gems incoming

I was going to do a post about milling herbs and selling inks when I noticed this lovely bit of information:

Jewelcrafting

• Meta gems with the Chaotic and Relentless prefixes now have a requirement of 3 red gems.
• New meta gems have been added: Agile Shadowspirit Diamond (Agility/3% critical damage), Reverberating Shadowspirit Diamond (Strength/3% critical damage), and Burning Shadowspirit Diamond (Intellect/3% critical damage). These new recipes are unbound and can drop from any Cataclysm creature. The new meta gems have a requirement of 3 red gems equipped.

Three new meta gems which will probably be much better for dps than Chaotic (basically fixing and making in worthless in one step).

This information means three things for Jewelcrafters:

1. Stock up on meta gems, if you want to profit from the undoubtedly high demand for these meta gems you'll need a large supply of them.
2. Get the designs asap, the first to cut them will make the most profit. Monitor the Auction House after 4.0.6 has been released and be prepared to spend thousands on these designs (and hope to make that investment back).
3. Stock up on Inferno Rubies; Chaotic, Relentless and the three new meta gems all have three red gems as a requirement. This probably means a lot of blue/green/purple rare gems are going to be replaced by Brilliant, Bold or Delicate Inferno Rubies.

I'm going to prepare for this by doing all three of the above steps. I might even buy loads of Carnelians to be transmuted to Inferno Rubies by my Alchemist but I'll have to do a pricecheck on that first since herbs are quite expensive on my server.
