All Gems In Diablo 4 & What They Do
In Diablo 4, gems are valuable resources that players can obtain throughout their adventures. They are used to augment and customize player equipment, adding an extra layer of depth and strategy to the game.
If one of your items has a gem slot, you can just put a stone in there by interacting with the gem in your inventory. Diablo 4 has seven different types of gems:
- Amethyst
- Emerald
- Ruby
- Topaz
- Sapphire
- Skull
- Diamond
Each of these gems has a different effect. This effect depends on the rarity and the type of the gem, as well as the type of item you slot it in.
