Gem types and Gem qualities
Diablo 4 brings back the Gem types and Gem qualities of past Diablo games. Each Gem type provides different bonuses, and these bonuses differ further depending on which equipment slot the Gem is socketed into (Armor, Jewelry, or Weapon). Bonuses increase as the Gem quality increases.
Gem types
Diablo 4 has the following 7 Gem types:
Gem qualities
And 5 Gem qualities:
Gem quality dictates how large of a bonus a socketed Gem provides (the higher quality, the better bonus). Higher quality Gems can only be found later in the game.

Crafting higher quality Gems
Diablo 4's Jeweler NPC crafts Gems for a Gold fee. Similar to past Diablo games, 3 Gems of the same quality and type can be used to create a Gem of the next quality (e.g., 3 Crude Topaz Gems --> 1 Chipped Topaz Gem). The higher quality Gem created, the higher the Jeweler's fee.
| Quality | Gold fee |
|---|---|
| Crude | 4,500 |
Adding Gem sockets to equipment
The Jeweler can add sockets to the item slots below for a fee of 1 Scattered Prism (per socket) and an amount of Gold based on the item's Item Power.
| Slot | Sockets |
|---|---|
| Helm | 1 |
| Torso | 2 |
| Legs | 2 |
| Amulet | 1 |
| Ring | 1 |
| 1H Weapon | 1 |
| 2H Weapon | 2 |
| Bow | 2 |
Unsocketing Gems from equipment
While players can insert Gems into socketed items themselves, they can't remove them. There's 2 methods to unsocket Gems via vendors, with one of them being free:
- Salvaging with the Blacksmith (preferred): Player's can use the Blacksmith's Salvage directly in Inventory service to get Gems out of items. Although the item is lost to salvaging, its Gems are placed back in the player's Inventory. Because the service is free, it saves a ton of Gold.
- Unsocketing with the Jeweler: Players should only use the Jeweler's unsocketing service if they wish to keep the socketed item afterwards. This method costs thousands of Gold based on the item's Item Power.
