Take a look at these beautiful wow gold makers.
Lately I have been having a lot of luck with Simple gems for wow gold. I don't believe this is a fluke. Everyone leveling will come across these gems and a lot of people will post them without really knowing their value and just 2 or 4 people undercutting can easily affect the price of the market. So if no one buys them for a couple hours their price is drastically reduced. You can often find these gems for 20-40% of their true market value. When I say simple gems I mean gems such as Citrines, Jade, Large Opals, Star Rubies, Azerothian Diamonds, Aquamarines and various Pearls. These are great items to buy up when you can find them at a good price. These are used in several professions for skilling up with low level gear, and are used heavily in Jewelcrafting for almost all of the early designs. So when these sell at normal market value it will probably be 5-10 gems at a time as they are being bought out to help level a crafting profession. I believe the prices for these gems will go even higher as many people find Inscription less profitable and switch off to something else (maybe Jewelcrafting.... the 2 in gold making professions?). I've been grabbing all the simple gems I can and re-posting for a significant profit. Rarely have a seen any of these come back after a 48 hour post. So next time you look in the auction house, take a look at these beautiful wow gold makers.
