It has the cold of the Icewyrm's breath up here does it not? Not only do I lack customers for my crafting skills, but I also lack stock of gems to sell! If you can bring me several uncut gems to replenish my stocks, I can teach you the skill of gem perfection. This will allow you to sometimes cut a perfect gem with increased bonuses when cutting a uncommon quality gem from Northrend.
