Socket guide
Every prismatic socket
Flawless Deadly Garnet (+Critical Strike). Stat weights are near linear over the range a few sockets cover, so the same gem wins in every socket.
Secondary stat order
Critical Strike (0.58) > Mastery (0.58) > Haste (0.55) > Versatility (0.52). Full Frost stat priority.
Meta and primary-stat gems
A meta socket takes its own gem and should always be filled. Primary-stat cuts are not ranked here; the ranking is the single-secondary epic cuts that go in prismatic sockets.

Methodology
Formula
DPS per socket = rating on the gem times the spec's stat weight (DPS per point) for that stat. Gem ratings come from the game's data at the current build; weights from the weekly SimulationCraft scale-factor sim.
Weights used
Frost Mage: Intellect 70.46, Critical Strike 40.98, Mastery 40.73, Haste 38.61, Versatility 36.98 DPS per point, on a 252,699 DPS baseline.
Why derived rather than simmed
One gem is a small fraction of total secondary rating, so simmed gem deltas sit below the noise floor at any sane iteration count and flip between runs. Weights are stable.

Frequently asked questions
What is the best gem for Frost Mage in Patch 12.1.0.69587?
Flawless Deadly Garnet (+Critical Strike) is worth 697 DPS per socket for Frost Mage on cleave, the most of any epic gem, so it goes in every prismatic socket.
What is the full gem order for Frost?
Flawless Deadly Garnet (+697), Flawless Masterful Amethyst (+692), Flawless Quick Peridot (+656), Flawless Versatile Lapis (+629). The number is DPS per socket from the spec's stat weights.
How many sockets do I have?
Check your character sheet: necks and rings can come with a socket, and the seasonal socket item adds one to a head, neck, ring, wrist or belt piece. Fill every prismatic socket with the top gem here and the meta socket with a meta gem.
Should I mix gems?
No. Stat weights are close to linear over a few sockets' worth of rating, so Flawless Deadly Garnet stays the best choice in every socket. Mixing only matters when two stats are within a couple of percent, and then either is fine.
Why is this derived from stat weights instead of simmed?
A single gem swap moves DPS by less than the sim's run-to-run noise at any sane iteration count. Stat weights measure the same stat value across the whole fight, exactly and stably.
How often is this updated?
Every Sunday after the weekly SimulationCraft bump, when the stat weights are resimmed.
