Soul Gems are used for enchanting weapons and armor at an Arcane Enchanter or recharging previously enchanted weapons. After using a soul gem (with the exclusion of Azura's Star and The Black Star) it is destroyed.
If a soul of a smaller size than the Soul Gem is collected, simply drop the Soul Gem from your inventory and pick it up. It will be empty and ready to receive another soul.
- Filled and empty soul gems can be purchased from general goods merchants, Court Wizards, and some members of the College of Winterhold.
- Arch-Mage's Quarters at the College of Winterhold.
- Can be looted from Dwarven automatons.
- Can be looted from slain mages.
- Can be mined from Geode Veins in Blackreach.
