Epic gems will be appearing in the next upcoming content patch 3.2, as well as changes to all other professions in order to compensate for blacksmithing's ability to add two new gems.
Let's think back to Burning Crusade for a second here. What happened to the blue gems of BC once epic gems arrived? Here I'll just tell you straight out: They became practically worthless. If you don't sell your gems now, you won't sell them later either.
There, that's all I have to say about blue gems, now to discuss the epics :D
In the upcoming content patch 3.2 you'll be able to prospect Titanium Ore into these epic gems. You will be able to obtain gems from transmutations (no word on specifics yet, possibly blue gems), pvp turn ins, and emblems oh heroism.
Expect Titanium Ore to go up 3000-5000% these next one to two weeks before they release this patch (atleast two weeks time, maybe a month or more). If you have Titanium Ore I would save it until the price becomes ridiculous and if you don't have Titanium Ore I would definately suggest buying it right now. Just be careful and watch out for prices skyrocketting due to speculation and people thinking that they have to buy as much ore as possible for their gem business.
Remember that prices will continue to rise for titanium ore until there are so many gems that profits suffer from the competition. Then you will slowly see titanium ore fall with the price of gems and eventually settle to what I predict to be around 1000% the current price of titanium ore.
One last point, Titanium Ore is increasingly dissappearing from the auction house due to speculation regarding this patch. Therefore, you should definately consider farming and since Icecrown is the best location for Titanium Nodes (Source) I would suggest checking out Bane's submitted route.
Geese this post just keeps getting longer... here's an excellent email I received a few days ago. I have asked Toriigate to try and come up with another fast search setup for epic gems:
Hi Markco,Torrigate sent me this as well:
Really enjoy your blog, thanks for spending RL time to share with the WoW
community. Toriigate/Hazmats of Ally Onyxia writing in.
Hope I can give back a bit here with my programmer background to help
describe some of Auctioneer's more advanced search features. Especially
since you're on Auctioneering tips.
I've found these two "General" style searches to be invaluable to factory
cut-gem production and JC disenchantables production.
Getting a search of only uncut gems I think is kind of tricky given that you
cannot use iLvl or Quality to differentiate between cut/uncut gems (which is
possible for uncut green gems). This search takes advantage of the raw
uncut gem naming convention of 2 words (ie Scarlet Ruby, Monarch Topaz,
Autumn's Glow, Earthsiege Diamond etc). Rare cut gems are all 3 words.
To lookup just uncut blue gems (check Regex checkbox):
Set Category to 'Gem' and Quality to 'Rare'
Save time getting your mats.
Additionally you can just click 'Invert' if you want to see what is
cheap/expensive in only the realm of cut blues.
Auctioneer/LUA's regex does not support logical "OR"s but you can use a
'set' to get a similar effect. The following search will list anything that
begins with Eternal followed by a word that starts with S -OR- E.
Lookup just Eternal Earths/Shadows:
Additional information on some of the pattern matching syntax is here:
Here’s the revised search string for uncut rare gems – was previously excluding Dragon’s Eye and Autumn’s Glow:
