Gold ring with sapphire found on Limestone Street

Found this ring this afternoon around 3:15pm on Limestone Street, right in front of the Camelot Café, near the Lexington Opera House. It's a 14k yellow gold band with a small square-cut sapphire in a bezel setting, about a size 6. The inner band is engraved with the initials KA. Ring is in decent shape but has a tiny nick on the bezel from being dropped on the sidewalk. I’m hoping to reunite it with its owner—please drop me a note if this sounds like yours, and tell me the initials you see inside or where you last wore it.
