Angelic's Rings?

[ScooterMcGee]

I see people telling barbs to wear em. I looked around thinking they'd be a unique ring but the only thing I found was the low set item one. I looked at Summit site and it says +12 life per clvl for 2 piece.
So I'm wondering does 2 of the same ring give u a 2piece set bonus therefor giving you +12 life per clvl or does this stack 2fold since it's, it's set bonus therfore giving you +24 life per clvl? I checked the diabloii.net site and the set bonus isn't stated at that.
Just a little clarification would be great, since I've found a few of these before but never kept em, and am currently playing a barb.
Or I could be totally wrong and the ring is something completely different then the one I'm thinking, well thanks in advance.

The angelic ring, paired with an angelic amulet, grant +AR based on character level.
Around level 75, that's ~1250 AR. Two rings work for double the granted AR.

Probably for the Attack rating bonus.
I must admit it's a nice bonus. I wear two Angelic rings and an ammy on a lvl 60 assassin and i get a +720 attack rating, +10 to dexterity, +75 Life

An IK barb with 2 Angelic rings and the ammy is one of the cheapest hell-capable builds, apart from a summon necro or hammerdin, and that character can solo all of the game, perhaps with a small problem regarding Oblivion Knights.

Just to clarify to Scooter, Black Market means he gets +720 AR per ring.
The bonus is on the Angelic rings. If you wear a angelic ring and different piece of the Angelic set, you will get the bonus. If you wear two angelic rings with another piece of the set, you will get the bonus double, so 24 AR per level.

If we just focus on the AR(the other parts will give other bonusses)
ring+ring = 0 ar per level
ring+amu = 12 ar per level
ring+armor(ringmail) = 12 ar per level
ring+sword(sickle) = 2 ar per level
ring+ring+amu = 24 ar per level

Well, you get the general idea.
Since any wording would leave it ambigious I figured I should make these examples. :)
