Another way jewelcrafters can use gems is by cutting them, preparing them to be used in socketed items. Gems come in many different colors and shapes. Different types of gems have different basic properties, and a gem's cut also determines the effect this gem will have. Jewelcrafters can learn several types of cuts for each kind of gem: the Azure Moonstone, for example, can be cut into a lustrous, stormy, solid, or sparkling Azure Moonstone, and each one of these cuts offers different bonuses when used in a socketable item. Placing cut gems into an item's sockets will add the bonuses of these gems to those of the item, allowing players to customize their equipment to better suit their individual play style or the different roles their class can wow power leveling fulfill.

At higher levels, socketed items and specially cut gems become an important part of an adventurer's "bag of tricks". Both armor and weapons can have sockets. Some socketed items can be found in dungeons, but the expansion will also introduce a lot of new recipes for all the professions, including many recipes that let leatherworkers, blacksmiths, and tailors create socketed items. Socketed items can be of uncommon, rare, or even epic quality. An item's sockets can also have a specific color; if you put a gem of a matching color in each socket, the item will reward you with a special stat bonus beyond the gems' regular effects. However, you can also put gems of a different color in these slots if you would rather have a specific gem's effect instead of the added bonus.
