Diablo 4 Gems explained

Gems are stones you can put into pieces of equipment to raise certain core stats or improve aspects of your character and you can equip gems by selecting on the Character menu and putting it in any of the pieces of armor or weapons you have with available sockets.

The Gems you can find in Diablo 4 are:

  • Amethyst
  • Emerald
  • Ruby
  • Topaz
  • Sapphire
  • Diamonds
  • Skulls

Gems are a good way of enhancing your gear since gems increase even more the key stats of your build. In Diablo 4, gems appear in three different tiers. There are the Crude gems, which are their weakest version and easily found, Chipped, the intermediate tier, and there is their complete version which is the higher tier.

Diablo 4 Crude Gems are the weakest version you can find in the game

Now, the enhancement received from a gem depends on the type of equipment into which it’s put into. When used in weapons, gems affect your character’s damage output in some capacity, from increasing your Ultimate damage to how many life points you receive from a kill. Equipped in armor pieces, such as helmets and pants, gems add effects that respond to incoming damage. They do so by increasing your damage mitigation, giving you more life points, or even increasing how much damage enemies receive by attacking you. But, if a gem is equipped in a piece of jewelry, then it increases your character’s resistance to elemental damage.

How to unlock the Jeweler in Diablo 4

While you can equip gems just by yourself in Diablo 4, there are other features involving gems that are only accessible through a Jeweler who is unlocked once you reach Level 20 with a character. Once you have the minimum level, a new Priority Quest called Gem Crafting appears for you to complete at Fractured Peaks. After that, Jewelers are found in other big cities in Sanctuary.

Now, with the Jeweler unlocked, you have access to several useful systems that will help you progress through the game. First, you can upgrade any jewelry you have, increasing the item’s Item Power as well as the buffs given by it. You can only upgrade a piece of jewelry a certain number of times depending on their tier and for each upgrade you must spend a specific quantity of materials and gold.

The Jeweler in Diablo 4 is the NPC you need to work on your gems

In the Jeweler, you can also add sockets to or retrieve the gems you have embedded into pieces of equipment. Just keep in mind that adding sockets is quite an expensive process, so consider if you’re going to use the modified equipment for a good period of time.

Jewelers are also the NPCs you need to talk to if you want to craft gems.

How to craft Gems in Diablo 4

While they can drop from enemies or come in chests, you can also craft gems at the Jeweler in Diablo 4. The gem crafting system is pretty simple, only requiring your character to be at either Level 20 or 40 and a specific number of either Crude or Chipped gems of a certain type to craft a new one of a better tier.
