Buff Atamathon's other eye.

The one that gets dropped by beating him.

It seems kinda weird that the reward for beating one of the strongest bosses in the game is worse than all four of the other unique gems, arguably.

The simple way would be to just give it a lot of stats(Which would be good, as it would give everyone a reward for taking on that big guy), but it is really fire themed, so maybe heavy buffs to Fire would help the uniqueness, as would stronger bonuses to Golems?

(Note, I don't mean the one the Wyrm drops. That's fine as it is, since it's got a unique if not that strong bonus, is a 100% drop, and is a key item anyways.)

Perhaps make it the complementary part of a set... if you've got both eyes, you get bonuses to all the stuff a golem does (fire, lightning, cold, arcane, physical). The golem-dropped eye should give lightning and cold as per the wyrm-dropped one, I think, with the only the two combined unlocking their actual potential.

Wearing them as a golem (via gem golem) should definitely give some kind of particularly impressive bonus. I'd imagine an across-the-board cooldown reduction for golem talents would be included, as a start, and possibly a tree mastery (for the two golem trees) increase. Throw on some +allres and +alldam, as per Atamathon itself (though obviously to a lesser degree ), on top of the above set bonii, and you've have something worthy of the challenge.

Possibly give the cd reduction and mastery bonus to Atamathon as well, though, to make things equitable
