Cyrce's Circlet and sim

Good day mages
I have a question about this ring because when I look up guides it tells me to get the gems that just give you stats, but when I sim my character with all the relevant gems it tells me to get the Thunderlords’s Crackling Citrine, Fathomdweller’s Runed Citrine, and Legendary Skipper Citrine.

The disparity between the two ring set up is about 21k dps difference, which seems like a lot so I just wanted to know what am i missing in this setup?
Also in the Thunderlord, fathomdweleer, and legendary skipper set up I seem to have around 19% crit and 28% haste 18% mastery and 12% vers with just my buff and no flask.

Edit: forgot to mention this was for Frost Spec

Icy Veins does recommend this one for raid, so it just depends on the guide. Most guides ultimately say to sim yourself to know for sure so it sounds like you’re doing everything correct :slight_smile:

Brb, need to go change my circlet gems…

Do your own sim when it comes to any gems. Its always the best
