All three are on the map, one is in the ruined tower, one is on a bandit's loot, one requires sleeping in the camp and rescuing the folks on the rock who will give you the one they have

you need 4 rings

No you need three.

FYI you don’t need to sleep at the camp if you use detect magic... but you will need to move to the far right of the map to find the folks who need rescuing... a rope comes in handy if you have one...

I found white and gold Cog-wheel rings, which ring i missed?

Black ring. It's inside the chest in the tower.

There was one on the corpse, one in the tower chest, one with the people you can rescue. I don't remember which was which, though.

It's red, not black.
