Free money

I was just scanning the auction house tonight and found Zephyrite on sale in the auction house for under 9g each.  You can buy these and cut them to any gem and then vendor the gem and get 9g in return for them. Of course the price of the gem on the AH is going to determine your profit. As a person looking to make a little bit of money on the side then this is just a few silver each time but tonight i bought out almost 200 of them all about 8g25s each so this made me a profit of 150g just for some afk crafting while I went and had some afk time.
