In Diablo 4, gems can be slotted into your gear to enhance your stats. This system can be confusing, so we’ll explain how gems work. Read on below for all gem effects, tiers, and how to craft them.
All Diablo 4 gem effects
The different gem types in Diablo 4 offer a range of effects, which vary based on whether they’re slotted into armor, jewelry, or weapons. Here’s a quick rundown:
| Gem Type | Armor Effect | Jewelry Effect | Weapon Effect |
|---|---|---|---|
| Amethyst | Damage Over Time Reduction | Shadow Resistance | Damage Over Time Increase |
| Diamond | Barrier Potency Increase | All Elements Resistance | Ultimate Damage Increase |
| Emerald | Adds Thorns | Poison Resistance | Damage to Elites Increase |
| Ruby | Max Life Increase | Fire Resistance | Resource Generation Increase |
| Sapphire | Fortified Damage Reduction | Cold Resistance | Critical Strike Damage to Crowd-Controlled Enemies |
| Skull | Healing Received Increase | Armor Increase | Life On Kill Increase |
| Topaz | Control Impaired Damage Reduction | Lightning Resistance | Lucky Hit Chance Increase |
Diablo 4 gem tiers
Each gem type in Diablo 4 is available in five tiers. As a gem ascends the tiers, the bonuses it offers become more potent. The progression is as follows:
- Crude
- Chipped
- Normal
- Flawless
- Royal
While the exact bonuses vary depending on the gem type, each increase in tier signifies a more powerful version of the respective gem.
How to craft gems
Increasing the tier of your gems in Diablo 4 is achieved through crafting. Crafting higher-tier gems requires multiple gems of the same type from the previous tier. For example, crafting a Chipped Amethyst would necessitate three Crude Amethysts, while crafting a Normal Amethyst would require three Chipped Amethysts.
In addition to the required gems, a certain amount of gold is needed for crafting, which increases with each tier. Notably, the leap from a Flawless to a Royal gem requires a significant gold investment, emphasizing the value and power of these top-tier gems. Remember to always weigh the cost and benefit when deciding to upgrade your gems.
