Pearl Diamond and Ruby Brooch

Pearl Diamond and Ruby Brooch is a treasure found in Uncharted 3: Drake's Deception. It can be found in Run to Ground.

After you shoot two goons and start your trek back up to street level, Nate shakes loose the first ladder, then you come to an area where Sully asks you to give him a boost. Go ahead and boost him up but look around for some wall pipes to climb up and after the 2nd or 3rd one you'll see the treasure.
