Choose your class
Take DPS results with a grain of salt — factors like raid composition, buffs, and fight mechanics all affect real performance. The value of this tool is experimenting: swap items in the list above and re-simulate to see how different gear choices impact your DPS.
Gems let you customize gear in World of Warcraft: The Burning Crusade Classic by slotting them into item sockets. This guide covers how sockets and meta gems work, how to read gem cuts and colors, and which gems to use — with the exact per-spec setup linked at the bottom.
Each gear set has one meta socket (usually the helm) that only accepts a meta gem. Meta gems have an activation requirement counting how many Red, Yellow, and Blue gems you have equipped — every gem of that color counts whether or not it matches its socket, and a hybrid gem counts for both its colors (an Orange gem = 1 Red + 1 Yellow toward the requirement).
The most-used DPS meta gem is the Chaotic Skyfire Diamond — +12 critical strike rating and +3% critical strike damage — which requires at least 2 Blue gems equipped. Tanks, healers, and mana-based casters use different meta gems; see the full meta gem list on Wowhead.
Every gem in the game below — filter by quality, color, or stat, or switch to Top-used by spec to see what the best players actually socket (from our WarcraftLogs data). Hover any gem for its Wowhead tooltip.
The best gems depend on your spec, phase, and which caps you still need (hit, etc.). Our per-spec Best in Slot pages list the recommended gems for each phase, based on what top-parsing players actually use:
