So after the last patch i noticed a large increase on the blue gems from fel iron ore.
Currently on my server a stack sells for 8-10g
Ive made 1.6k gold in a day doing nothing but running from the AH to the mailbox.
What you need is the ability to prospect Fel Iron Ore, not sure what that is but my JC is currently 355. Your also going to need about 200 startup gold.
SO what you do is buy as much Fel Iron Ore as possible.
you can probobly get about 20 stacks.
PROSPECT EVER SINGLE PIECE OF ORE!!
My personal best was from 40 stacks i got 32 blue gems and 128 greens.
Cool thing is that even if you dont get a blue gem, your not losing any/much gold per stack.
Now you can either Cut and sell or just sell the blue gems.
As for the greens, cut and sell, you can get about 1.5-3g per green gem,
One stack of Fel Iron Ore = 8-10g
4 green gems sold on the ah 6-12g
any blue gems = PURE PROFIT
Hope this helps any JCs like me that were suffering with the prices of JC patterns.
Enjoy.
