What does Mentis Gem do?

[THE GOLDEN KING]

Hello what does this gem do? Why is it worth so much, and can I put this gem in something level 41 and under and still be better than a precise fury?

The gem has an aura, is a exclusive and hard drop from halloween, the details of it you can find in game, crafting stations>upgrade>Upgrade browser.

It's Just a vanity gem imo
