So I ended up with 2 or 3 Noble Topazes and wasn't sure what to do with them so I decided to check the AH to see what they were going for. There were a couple of auctions for around 3 or 4 gold but what was funny were the auctions for 2.99g, 2.75g and 2.50g. I looked at what I could get for the Noble Topaz at the vendor and it was ... 3g. I ended up vendoring mine. Do people even pay attention when they post at the AH?
