Gems

Gems are items that can be added to sockets, yielding stat bonuses for the socketed item. Gems can be removed at the loss of the item by Xander or destroyed to free up the socket they were in by Gort in Ektbatan. There are two types of gems, regular and artifact gems.

Regular Gems
Regular gems come in different grades, which determine their value and how much they will increase a stat. The grades, in order of increasing value are: cracked, normal (e.g. a normal agate is simply called an agate ), superior, perfect and divine. Divine gems are also considered Artifacts and are exceedingly rare.

Artifact Gems
Artifact gems are much rarer and more valuable than regular gems. They do not come in different grades but generally give better stat bonuses than regular gems (with the exception of the Gem of False Hopes).
