Gold ring with emerald near Bronson Park

Found a ring this afternoon around 3:15pm, lying on the sidewalk near the Bronson Park fountain in downtown Kalamazoo. It's a 14k yellow gold band, about 6-7mm wide, with a small oval emerald set on top. The inside of the band has a faint engraving 'KM' and there's a tiny scratch along the outer edge from a scrape in the grass. The ring is in good shape overall, and I’d really like to help reunite it with its owner—if you know this ring, tell me what the engraving says or describe the setting and I’ll get it back to you.
