Jeweler Overview
In Diablo 4, players can greatly enhance their equipment and progress through the game by using Jeweler features, such as unsocketing gems, adding sockets, upgrading jewelry, and crafting gems. This guide will explain how to use the Jeweler and all these features. We also have a guide that covers the entire gear system within Diablo 4, which is relevant and which we recommend reading as well:
Gear Systems in Diablo 4How to Unlock The Jeweler
When you reach Level 20, a new objective will direct you to Kratia, the Jeweler in Kyovashad within Fractured Peaks, as a priority quest.
How to Craft Gems
Upon completing the quest, you will have access to the crafting system and can create any gem you desire, provided you have the necessary materials. The system allows for the creation of more potent gems, by using gemstone fragments that have been found or dropped. Gem fragments can be discovered throughout the world, as drops from Whisper Caches, or obtained by defeating enemies. The higher the tier of gem that is crafted, the more fragments it will cost. The same naturally applies to further tiers as well, and so on.

Visiting the Jeweler and upgrading gems will result in even better stats when placed in your gear.
How to Add Sockets
Aside from crafting gems, you can also place gems in sockets on your characters’ gear to boost their stats. The following types of gear can have sockets:
- Head – 1 Socket
- Chest – 2 Sockets
- Pants – 2 Sockets
- Amulet – 1 Socket
- Ring – 1 Socket
- 1-Handed Weapon – 1 Socket
- 2-Handed Weapon – 2 Sockets
- Off-Hand Focus – 1 Socket
- Bow – 2 Sockets
However, some items drop without any sockets. In such cases, you can visit the Jeweler to manually add a socket to the item, but this will require a 
Scattered Prism. These can be obtained by looting treasure Goblins, completing legion events, or as a drop from World Bosses, such as Ashava the Pestilent.
How to Remove Gems from Sockets
The Jeweler allows you to remove gems from item sockets, for a price. This costs a certain amount of Gold, with the cost going up as the Item Power of the item itself increases.
Removing gems this way is only useful if you wish to replace the gem with a different type of higher quality of gem. Otherwise, if you are simply upgrading the gear piece itself (and plan to salvage it), paying to have the gem removed is pointless, since the act of salvaging it is free of cost and returns your gem to you. Check out our Blacksmith Guide for more information about how to salvage items.
Blacksmith GuideUpgrading Jewelry
The Jeweler is also helpful for upgrading jewelry, which can be done spending gold and materials, similar to other gear upgrades at the Blacksmith. However, it is not recommended to upgrade Magic or lower-tier Items, due to the increasing costs of gold and materials.
- Rare items can be upgraded three times.
- Legendary and Unique items can be upgraded four times.
Note: the cost for each upgrade level will increase.
| Upgrade Rank Level | Rare Jewelry Upgrade Cost | Legendary + Unique Jewelry Upgrade Cost |
| Rank 1 | Iron Chunk x5 + 4,800 Gold | Iron Chunk x5 + 6,750 Gold |
| Rank 2 | Iron Chunk x5 + Silver Ore x4 + 11,250 Gold | Iron Chunk x5 + Silver Ore x4 + 13,500 Gold |
| Rank 3 | Iron Chunk x8 + Silver Ore x6 + Veiled Crystal x3 + 4,800 Gold | Iron Chunk x8 + Silver Ore x6 + Veiled Crystal x3 + 42,500 Gold |
| Rank 4 | Iron Chunk x12 + Silver Ore x7 + Veiled Crystal x6 + Abstruse Sigil x2 + 135,000 Gold | Iron Chunk x12 + Silver Ore x7 + Veiled Crystal x6 + Abstruse Sigil x2 + 135,000 Gold |
Seasonal Mechanic
During Season 3, the Jeweler will also allow you to craft Governing Stones or Tuning Stones with Shattered Stones that drop from defeating construct enemies. You can find a new tab at the Jeweler called “Craft Construct Items“, where you can spend 200x Shattered Stones and 20x 
Iron Chunk in order to get an Uncertain Seneschal Stone Cache, which will reward you with Governing Stones or Tuning Stones upon opening.
Overall, the Jeweler is an important NPC that should be visited on a regular basis to help you improve your equipment and advance through your Diablo 4 journey.
