Ruby

For the magic prefix, see Ruby (magic prefix).

Rubies are red gems, and are socketable items in Diablo II and Diablo III.

Diablo II

Like all other gems, Rubies grant bonuses that are related to their color. The red in Rubies signify the Elemental power of Fire. Socketing a ruby in Weaponry adds Fire damage, while Shields earn Fire resistance, and in Helms and Body Armor it increases life, which, in-game, is also associated with the color red. Crafted Items can be made with Rubies, and Blood Items have bonuses centered on increasing the wearer's life and recovering life.
