Jeweler

The Jeweler in Diablo 4 offers two different kinds of services, gem management and jewelry upgrades.

Upgrading Jewelry

Jewelry can be upgraded to make the affixes of the jewelry more powerful and increasing their resistances.

Gem Crafting

The Jeweler is able to upgrade gems to higher qualities assuming you have the right amount of gems to make the upgrade and a certain amount of gold.
