Gems

From Diablo 4 Wiki

Gems can be socketed into armor, weapons or jewelry to add additional stats depending on their tier (quality/grade). Your main source of gems is drops from enemies but you can also get them from chests, part of a reward cache or harvested from ore nodes.

There are 7 types of gems:

They come in 5 tiers:

  • Crude
  • Chipped
  • Normal
  • Flawless
  • Royal

Gem fragments found as loot can be combined to create whole gems at the Jewelers.


Using Gems

Certain items can come with 1 to 2 sockets.

Number of Gem Sockets Available on Item Types
Amulet Ring Helm Chest Legs Gloves Boots Weapon Offhand Shield
1 1 1 1-2 1-2 0 0 1-2 1 1

However, the Jeweler can also add sockets to an item for gold and Scattered Prisms. Scattered Prisms are very difficult to find and your best bet to finding them is World Bosses, next would be the elusive Treasure Goblin and the other is salvaging Legendary items at the Blacksmith.

Once socketed a gem can be unsocketed from an item by the Jeweler for gold. This is useful when you wish to stop using an item or if you are able to upgrade the gem.


Gem Effects

Socketing an item with a gem will add the following effects to it.

Type Weapons Armor Jewelry
Skull +Life per Kill +% Healing + Armor
Emerald +% Critical Strike Damage to Vulnerable Enemies +Thorns +% Poison resist
Diamond +% Ultimate Skill Damage +% Barrier Generation +% Resist All
Ruby +% Overpower Damage +% Maximum Life +% Fire resist
Sapphire +% Crit dmg to Crowd Controlled (stun) enemies +% dmg reduction while Fortified +% Cold resist
Topaz +% Basic Skill Damage +% dmg reduction while Control Impaired +% Lightning Resist
Amethyst +% Damage Over Time +% Damage Taken Over Time Reduction +% Shadow Resist


Gem List and Effects

Each class will benefit more from some gems than others and in the table below the effects of each gem type on particular types of gear are highlighted.

Whether it's resistances, more damage or increased Life, choosing your gear combination coupled with slotted gems can greatly enhance your chosen build. How you approach this depends on your play style, the situation you are trying to overcome, and of course, your gear.
