Gems can be socketed into armor, weapons or jewelry to add additional stats depending on their tier (quality/grade). Your main source of gems are 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 5 tiers:
- Crude
- Chipped
- (normal)
- Flawless
- Royal
Three of the same type can be combined to form a single gem of that type but one tier higher. For example, 3 Flawless Diamonds form 1 Royal Diamond. This service is provided by Jewelers.
Using Gems
Certain items can come with 1 to 2 sockets.

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 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.
