Diablo 4 gems – how to upgrade best gems for every class in Season 3

Want to know how to upgrade your gear with Diablo 4 gems in Season 3? Look no further. Gems can be found across Sanctuary’s open areas and can be added to your equipment to boost their stats. Slot them into sockets found on armor, weapons, or jewelry and you can hone your build even further. These effects range from damage resistance to gaining health on a kill.

While Diablo 4 gems in Season 3 aren’t very hard to find, you won’t make the most of them unless you upgrade them with the help of a jeweler. Season of Blood drastically changed gems as you can now treat them as crafting materials. They no longer hold up precious inventory space. And Season of the Construct makes inventories less busier thanks to the ability to purchase extra Stash slots. Before you test your might against Diablo’s timeless brand of dungeons, here’s how to skip the campaign in Diablo 4 and how to level up fast in Diablo 4. Check all the details in Diablo 4 Season 3 as well.

How to upgrade Diablo 4 Gems in Season 3

You can upgrade Diablo 4 gems at a jeweler once you reach level 20. The quest Gem Crafting will task you with speaking with the jeweller Kratia who can be found in Kyovashad. One conversation later, you can speak to any jeweler across Sanctuary and upgrade your gems.

Creating them involves combining three crude crystals or skulls of the same type and forking over some coin. Reaching level 40 lets you combine three of these upgraded gems for an even more potent gem to slot into your equipment. These bonuses will help you tackle bosses and even a World Boss.

Level 60 and 70 grant you Flawless and Royal gems respectively. These can be created by combining three gems of the previous rarity. This means that three Flawless gems can be converted into one Royal gem and so on. While you can equip crude crystals for a decent boost, I’d advise upgrading them to boost their stats whenever you have enough resources for it.

You can add more sockets to gear with Scattered Prisms obtained from Treasure Goblins, salvaging Legendary gear, or a World Boss.

Here’s a handy list of the resources you need to upgrade your gems:

To craft	Combine three to get (level 20)	Combine three to get (level 40)	Combine three to get (level 60)	Combine three to get (level 70)
Chipped Amethyst	Crude Amethyst	Amethyst	Flawless Amethyst	Royal Amethyst
Chipped Diamond	Crude Diamond	Diamond	Flawless Diamond	Royal Diamond
Chipped Emerald	Crude Emerald	Emerald	Flawless Emerald	Royal Emerald
Chipped Ruby	Crude Ruby	Ruby	Flawless Ruby	Royal Ruby
Chipped Sapphire	Crude Sapphire	Sapphire	Flawless Sapphire	Royal Sapphire
Chipped Skull	Crude Skull	Skull	Flawless Skull	Royal Skull
Chipped Topaz	Crude Topaz	Topaz	Flawless Topaz	Royal Topaz

All gems in Diablo 4

You’ll find a variety of Diablo 4 gems across your time in Sanctuary. Crude crystals (the basic variant of gems) and skulls are fairly common drops from ore veins that are scattered through the map. Glittering ore veins and chests have a higher chance of dropping gems.

There are seven different types of Diablo 4 gems:

• Amethyst
• Diamond
• Emerald
• Ruby
• Sapphire
• Skull
• Topaz

Each of them provides different benefits based on their tier and rarity. Standard gems can further be upgraded to enhance their effects. The type of equipment that you add them to matters as well, with unique effects for weapons, armor, and jewelry.

Best Diablo 4 gems for every class

Here are the best Diablo 4 gems that can enhance the potential of every class in Diablo 4 Season 3:

• Barbarian – Use Rubies in weapons to deal more overpower damage with moves like Bash. The best Diablo 4 aspects can also grant overpower damage. Emerald in Armor enhances Diablo 4 thorns damage so most close-up classes can use this against attackers.
• Rogue – Sapphires are a good pick for Rogue weapons as they can benefit from the critical strike damage to crowd-controlled enemies. Skulls are great for all classes since they grant health on kills when added to weapons.
• Necromancer – Consider the Topaz for a boost in basic skill damage. This lets you be even more of a threat alongside minions. It’s a good option on armor too since the Necromancer’s mediocre health pool make them susceptible to control impairment.
• Sorcerer – Improve your damage over time effects with an Amethyst in your weapons.
• Druid – Diamonds are great for nearly every item for Druids. Ultimate Skill damage can make already devastating ultimates even more potent. Barrier generation via Diamonds in armor can protect you from enemies while adding them to jewelry grant resistance to all elemental damage.

Upgrade gems at the appropriate levels to amp up your builds

While the game won’t remind you, check the jeweler’s wares and skills out at every 10 levels of experience, just to be safe.

How to unlock the jeweler in Diablo 4

Gems in Diablo 4 can have a serious impact on your existing gear. Adding them can be done at your convenience. But since you can only unsocket gems from gear at the jeweler, a trip to town is due if you’re switching out your equipment for new loot.

To unlock the jeweler, you must first level your character up to level 20. This will let you take on the Gem Crafting priority quest, unlocking the jeweler in Kyovashad – Kratia. Once you’ve completed the quest you will be able to use any jeweler across Sanctuary.

Diablo 4 Jeweler locations

Here is a list of all of the jewelers and their locations:

• Fractured Peaks – Kratia in Kyovashad
• Dry Steppes – Tungal in Ked Bardu
• Scosglen – Realyn in Cerrigar
• Kehjistan – Kaveh in Gea Kul
• Hawezar – Alyoni in Zarbinzet

They’re great additions to your equipment regardless of class and remapping your gems before encounters can mean the difference between survival and defeat. Several enemies’ attacks can be weakened with the right type of gem in your armor. For more tips on all things Diablo, check out how to get a mount in Diablo 4 and the best classes in Diablo 4 before upgrading your gems. While you can no longer use Malignant Hearts or vampiric powers, Season of the Construct brings in new mechanics.

The new Diablo 4 Seneschal companion lets you unleash massive damage on foes across all classes: Rogue, Sorcerer, Necromancer, Barbarian, and Druid. These can be enabled with the right Governing Stones and Tuning Stones. Take part in new Vault dungeons in Diablo 4 as well. Season of the Construct is out on PC, PlayStation 4, PlayStation 5 (PS5), Xbox One, and Xbox Series X|S.
