Hello. Have some Jewelry items made (Copper Ingots only). Didn't use any gems for this (did not have any on hands at the time, will try to update info when I can). For now these are all from Copper, Tin and Bronze Ingots Jewelry, from level 1-30. The higher your Outfitter level, the better your results will be, at level 40 and 50, I speculate the Metal Jewelry will have more stat modifiers, different kinds of stat modifiers, higher bonuses too. With added Gems, it will even be a lot better of course.
