how to jewelcraft iron ore
In jewelcrafting you’ll only use precious metals (aside from copper), iron is used by other tradeskills. Next you’ll be using Silver, then Gold, then Platinum, and finally Orichalcum (Electrum would be next, but it is for Ascended gear later on)
Iron ingots are created using armorsmith, huntsman, artificer or weaponsmith starting at 75.
thank you kind sirs
There is a jeweler recipe that uses iron but the result is soulbound on acquire.
