Gems are the final touch in crafting, allowing you to add up to 4 additional modifiers on top of an item’s existing 6. While these modifiers have a lower value range, they provide a way to refine and optimize powerful gear.
Gems can only be applied to items with an empty gem socket. You can create a gem socket by using a Jeweler’s Orb, but each item can have only one socket.
Gems can be removed using a Gemcutter’s Prism, returning the original gem intact. Like other items, gems can be corrupted. Once corrupted, they cannot be removed.
