Gems

Gems can be socketed into armor, weapons or jewelry to add additional stats depending on their tier (quality/grade). Your main source of gems is drops from enemies but you can also get them from chests, part of a reward cache or harvested from ore nodes.

There are 7 types of gems:

They come in 4 tiers:

Chipped
Normal
Flawless
Royal

Gem fragments found as loot can be combined to create whole gems at the Jewelers. They are also used by the Alchemist to craft Elixirs and Incense.

Using Gems

Certain items can come with 1 to 2 sockets.

Number of Gem Sockets Available on Item Types
Amulet	Ring	Helm	Chest	Legs	Gloves	Boots	Weapon	Offhand	Shield
1	1	1	1-2	1-2	0	0	1-2	1	1

However, the Jeweler can also add sockets to an item for gold and Scattered Prisms. Scattered Prisms are very difficult to find and your best bet to finding them is World Bosses, next would be the elusive Treasure Goblin and the other is salvaging Legendary items at the Blacksmith.

Once socketed a gem can be unsocketed from an item by the Jeweler for gold. This is useful when you wish to stop using an item or if you are able to upgrade the gem.

Gem Effects

Socketing an item with a gem will add the following effects to it.


Type	Weapons	Armor	Jewelry
Skull	+Life per Kill	+% Healing	+ Armor
Emerald	+% Vulnerable Damage	+ Dexterity	+% Poison resist
Diamond	+% Ultimate Skill Damage	+% Barrier Generation	+% Resist All
Ruby	+% Overpower Damage	+% Maximum Life	+% Fire resist
Sapphire	+% Critical Damage	+ Willpower	+% Cold resist
Topaz	+% Basic Skill Damage	+ Intelligence	+% Lightning Resist
Amethyst	+% Damage Over Time	+ Strength	+% Shadow Resist

Gem List and Effects

Each class will benefit more from some gems than others and in the table below the effects of each gem type on particular types of gear are highlighted.

Whether it's resistances, more damage or increased Life, choosing your gear combination coupled with slotted gems can greatly enhance your chosen build. How you approach this depends on your play style, the situation you are trying to overcome, and of course, your gear.
