Gems

Gems can be inserted on socketed items to provide bonuses or used on some crafting recipes.

There is 5 qualities of gems and each one requires a specific level to be equipped:
 * Cracked, lvl 3
 * Scratched, lvl 15
 * Good, lvl 30
 * Polished, lvl 40
 * Perfect, lvl 50

After inserting a gem into an socketed item, the level required to be equipped will change to the gem level if it is higher than the item level.
