Throughout your Diablo 4 adventure, you’ll come across colorful gems known as jewels. The seven types are ruby, sapphire, emerald, amethyst, topaz, diamond and skull. Each of these gems can be equipped with weapons, jewelry, and armor, can improve your character’s stats, and provide other useful effects.
Gems come in varying degrees of rarity (from raw to royal) and can be obtained by completing quests, visiting jewel shops, or opening ores and treasure chests. With all the different types of enhancements in addition to classes, you may be wondering which gem is best for your characters to defeat enemies and survive the upcoming challenges in the best ways possible.
7 Deal damage with Ruby
A gem of fire, the Ruby gem gives characters distinctive power boosts in addition to their fire-based attacks. Ruby weapons increase Overpower damage, Ruby armor increases maximum life, and Ruby Jewelry adds resistance to fire attacks.
Overwhelming damage is crucial for tanky characters like the Barbarian, where you can convert resilience into extra attack power. By using the Ruby weapon, the Barbarian can significantly increase Overpower either after using an ability like Bash or even with Earthstriker’s aspect or other passive abilities.
6 Crowd control with Sapphire
An icy cold gem of Diablo 4, characters with sapphire can deal cold damage in addition to freezing enemies. Equip Sapphire on weapons to increase damage against crowd-controlled enemies, on armor to reduce damage when hardened, or on jewelry to increase resistance to cold.
Diablo 4 allows you to trigger crowd control to damage and attack multiple enemies at once, but the Sapphire weapon can make this process much more efficient. Not only can it slow, freeze or stun enemies, each attack will also drain more of their health. Rogue is one of the best characters to use with Sapphire as their skills allow them to rush through enemies like swiss cheese while constantly triggering Daze.
5 Puncture with an emerald
Emerald is a gem of protection and resistance in Diablo 4. It increases critical hit damage in weapons, increases poison resistance in jewelry, and adds spikes to armor. Thorns still allow you to take damage, but cause attackers to take damage back. The green gem can also increase damage done to enemies in vulnerable states such as being stunned.
Barbarian is one of the best classes for the Emerald gem if you like to fight up close and personal. Adding this gem to your armor will give your character an extra means of dealing damage, especially to enemies that constantly deal damage to you. Without needing special skills or armor to increase spikes, Emerald armor allows fights to end faster while reducing the damage you take in the process.
4 Cast Magic With Topaz
Gems that symbolize calm, Topaz gems in Diablo are known for drawing and protecting against electricity. Topaz increases skill damage on weapons, reduces crowd control damage on armor, and increases lightning resistance on jewelry.
While useful to wear on armor for a wide variety of debuffs and damage, Necromancers see Topaz’s best use on weapons, especially in the early game. With all the spells a Necromancer can use, and all of them fairly weak to begin with, Topaz weapons make skills universally stronger and can greatly ease your difficulty curve.
3 Apply with amethyst
Known as the Gem of Time, Amethyst deals Bleed damage to enemies where mild damage is dealt every instant like poison. With amethyst, weapons can increase damage over time (DoT), armor can reduce damage, and jewelry can increase resistance to shadow attacks.
You can’t go wrong with any class that can inflict Bleed, Poison, Burning, or Blight on enemies with Amethyst weapons. The Sorcerer, Necromancer, and Rogue classes have attacks and skills that contain many of these effects. Due to the increased damage from certain attacks, you will be able to finish off enemies faster.
2 Stay alive with a diamond
Diamond, a gem of light and resistance, has excellent protective properties. It is also the rarest gem in the game, mostly found as a quest reward. Diamonds can increase ultimate damage in weapons, increase barrier protection in armor, and add resistance to any item in jewelry.
Elemental resistance comes in most handy for druids. Since many skirmishes will strain druids, diamond jewelry does a good job of mitigating this problem, making battles more manageable and ending faster. Druids are also one of the three classes that use barriers, and diamond armor will give your barriers extra life so your chances of sticking through a tough fight will improve.
1 Heals with a skull
While a common depiction of death, the Skull Gems are about life and rejuvenation. Regardless of your class, you might find skull gems tempting on any gear. Skull gems can add Life on Kill to weapons, make potions more effective with armor, and increase overall defense with jewelry. Life on Kill allows you to restore a small amount of life after defeating an enemy.
The abilities of the skull gems are pretty universal. This allows you to double or triple dip with another type of gem you may be eyeing. For example, if you like the idea of having emerald armor for your barbarian, you can also equip skull jewelry or weapons as a great addition to the Thorn buff armor.
