Perfect Sapphire

A Gem in Diablo II is one of three small items that can be placed in a socket to enhance your gear. There are different types as well as qualities of these gems, both deciding what kind of stats you will receive when socketing it into gear. Although they cannot activate bonus stats when placing in a specific order, gems are still a valid in-game currency for another reason. Other than item enhancement, these gems can be used in a variety of Horadric Cube recipes, reaching from Rerolling of magic items to upgrading gear and runes. Gems can be used to start the accumulation of in-game wealth with successful trades, and because you're more likely to find various gems while playing than Mid or High Runes, they make it easier for the newer members to involve themselves with trading.
