Covetous Shen – Gems and Sockets in Diablo 3

Covetous Shen – Gems and Sockets in Diablo 3


Diablo 3 kept several of the main components from Diablo 2, sockets and gems to fill them. Although Diablo 2 had many different varieties of gems, Diablo 3 has simplified it into 4 gems to cover all the functions needed, in three different types of sockets. Covetous Shen, whom you rescue about half way through Act 2, is critical in upgrading these gems and getting the best results from your sockets.


Basic Gem Properties


Each of the gems fills 3 different types of sockets. The sockets used in Diablo 3 are weapon, helm, and other. The color of gem is the basis for the effect. The quality of gem determines the modifiers for each gem.

+ Vitality (in armor or jewelry)

Upgrading Gems

With patch 1.03, upgrading gems in Diablo 3 has improved significantly. Covetous Shen upgrades the quality of the gems for you, for a small fee. Each upgrade requires a number of gems one tier lower than the the quality of gem you are making. Some gems require materials from Nightmare, Hell, or even Inferno difficulty.  These are summarized in the table below:
