[DC] what would Batman do with a diamond ring that he found in the gutter?

Batman‘s a world class detective, at a cursory glance, he could tell the ring’s been lying there for months just going unnoticed. He also knows, based on cut, weight and clarity, that it’s value is at least breaking the 50k mark.  Obviously an expensive ring, but not so expensive that it’s overly unique or rare (meaning it should be in a museum)


Let’s say he’s in the middle of an investigation... trying to track down Mad Hatter before he kills again.  Would he stop to pick it up and use up time to run it to a police station’s lost and found? Would he even bother to take it with him?  Would he leave it up to fate for someone else to find?

He'd likely pick it up just to keep some drug addict from pawning it or trading it for meth.

Then, as Bruce Wayne, he'd put an ad in the paper or ask around town among the people that could afford a 50K ring if they lost one and have them describe it. There would be no reward requested, but he might ask for a charitable contribution if they could afford it to the Wayne Foundation or something.

If there's no response, he'd then sell it in a charity auction with the proceeds going to help the needy.
