Gold ring with ruby and engraving inside

I found a gold ring yesterday around 4pm near the St. Armands Circle fountain in the Sarasota-Bradenton area, right by the brick sidewalk outside the little cafe. It's a 14k yellow gold band, about 1.8 mm wide, with a tiny round ruby set in a bezel. Inside there's an engraving that reads 'M.B. 1999' and a faint floral pattern along the outer edge; it has a brushed finish and a small scratch from wear. I picked it up because it looked valuable and I really want to help reunite it with its owner—if this sounds like yours, send a message here and we can arrange a safe meetup to verify.
