Diablo 4: All Gem Upgrade Levels & Types

In Diablo 4, players can find seven Gem types, each available in five different levels. As the level of a Gem increases, its effects also increase. To level up their Diablo 4 gem levels, head to Jeweller, who can combine three Gem of lower levels into a single Gem of the next level.

What Are Gems?

Gems are used as a means to add unique effects to your gear and benefit from them in combat. Upon reaching Level 15, players can acquire gems through various means, such as searching chests, looting enemies, or interacting with objects. 

All Gem Levels In Diablo 4

In Diablo 4, Gems are categorized into five different levels, beginning with Crude at the lowest tier and culminating with Royal at the highest tier. As players interact with Jewellers, they have the opportunity to elevate their Gem levels to the next tier, unlocking more powerful effects and benefits.

Gem Level	Level	Craft Requirement
Crude Gem	Level 15	N/A
Chipped Gem	Level 20	3 Crude Gems & 4,500 Gold
Standard Gem	Level 40	3 Chipped Gems & 12,500 Gold
Flawless Gem	Level 50	3 Standard Gems & 18,000 Gold
Royal Gem	Level 60	3 Flawless Gems & 50,000 Gold

As your character progresses and gains levels, you will have the chance to utilize higher-tier Gem levels in Diablo 4.

All Gem Types

Diablo 4 has seven Gem types that players can collect throughout their journey. I would recommend paying more attention to the Gems, as they offer unique bonuses and enhancements that directly impact your weapon, armor, and jewelry.

Gem	Weapon Bonus	Armor Bonus	Jewelry Bonus
Ruby	Buffs Overpower type Damage	Buffs Maximum Life	Buffs Fire Resistance
Sapphire	Buffs Critical Strike Damage to Crowd-controlled Enemies	Reduces Damage when Fortified	Buffs Cold Resistance
Topaz	Buffs Basic Skill Damage	Reduces Damage while Impaired	Buffs Lightning Resistance

Skull	Health regenerates after kills	Buffs Healing amount received	Buffs all Armor Stats

How To Upgrade Gem Levels?

Players can upgrade their gem levels through Jeweller once they reach level 20. The Gem Crafting quest introduces players to Kratia, a Jeweller located in Kyovashad, whom they must speak to in order to initiate the gem upgrading process. After a brief conversation with Kratia, players will gain access to any Jeweller across Sanctuary to upgrade their gems.

• Combine three gems of the previous rarity to create the higher-level gems.
• You will also need gold in addition to three gems.
• Once you reach level 40, you can combine three of the upgraded gems for even more powerful gems.
• At levels 60 and 70, you unlock the ability to create Flawless and Royal gems, respectively.

That’s all you need to know about the Gem Levels Upgrade. I think the best gem choice depends on the class and build. I will also recommend looking at the Best Aspects for your class to fully utilize your gems and take advantage of them in combat.
