How to upgrade Gems in Diablo 4?

To upgrade Gems in Diablo 4, you’ll first need to reach Level 20. After that, head over to the Jeweler, speak to him, and you’ll get the option to upgrade your gems there.

As we mentioned earlier, there are seven types of Gems and each of them comes in different variants. You can craft the crude variants of Gems at Level 15 and their better counterparts unlock at Levels 20, 40, 50, and 60, respectively. As you level up, you’d be able to upgrade the crystals by chipping in three previous Gem variants and some Gold.

Check the table above to get an idea of the required levels, crafting costs, and effects of the Gems.

How to unlock the Jeweler in Diablo 4?

To unlock the Jeweler in Diablo 4, you need to complete the priority quest after reaching Level 20. The quest requires you to go and see the Jeweler Kratia in Kyovashad, Fractured Peaks. Upgrade a Gem as he asks after which he will be available in every major location in Sanctuary.

The Jeweler helps to upgrade the Gems which can in turn boost their stats, ultimately helping in taking down enemies and bosses in the game.

Malignant and Caged Hearts in Diablo 4

While not technically Gems, Caged Hearts can be slotted into Jewelry in a similar way to gems. Rather than the small percentage-based enhancement of Gems, they give powers similar to and sometimes greater than Legendary Affixes.

Adding the Infested Sockets in which Caged Hearts can be slotted is also done via the Jeweler but both the Sockets and Hearts have corresponding categories that work together differently than Gems. For a more detailed guide on Malignant and Caged Hearts, check out our in-depth guide.

Use of Gems in Diablo 4

Gems are those items that help to increase the stats of armor, jewelry, and weapons in Diablo 4. These in turn boost the stats of Ultimate Damages, Damage Over Time, and much more.

Equipping these items is quite essential in defeating powerful bosses both in the early and later stages of the game.
