Found a gold wedding ring engraved with 'Forever Yours' in the parking lot of Detroit Metro Airport.

I found a beautiful gold wedding ring while walking in the parking lot of the Detroit Metro Airport. It has an engraving on the inside that says 'Forever Yours' and appears to be quite valuable. I don't know how long it had been there, but I want to return it to its rightful owner. If you believe it's yours, please describe the ring in detail so I can verify before handing it over.
