After some searching on the mmo-champion forums, I found the prices of epic gems and a small titanium ore prospecting data sample. Here's the thread: http://www.mmo-champion.com/index.php?topic=67563.0
and the prospect rate thread: http://www.mmo-champion.com/index.php?topic=67480.0
Prices will be 10,000 honor or 15 emblems of heroism. The prospect rate seems to be about 25%, or 1 per stack of 20 ore. It is also possible to get Uncommon and Rare quality gems from the prospect. 10 titanium dust can be turned in for 1 Jewelcrafter's token.
For transmuting, see this thread: http://www.mmo-champion.com/index.php?topic=67505.0
The more interesting transmute is for the Cardinal Ruby, which takes 9 Forest Emeralds. Sounds like a good way to get rid of those rare gems that don't sell well or sell cheap.
With all these methods of obtaining epic gems, I'm beginning to wonder if holding on to Titanium Ore will be worth it. I'll have to give it more thought before I hazard a wild ass guess.
