Silver ring with inner engraving found near Bullring, Birmingham

I found a silver-toned ring this afternoon around 2:15 pm on the pavement outside the Bullring Shopping Centre in Birmingham, West Midlands. It’s a plain, medium-width band with a brushed satin finish, probably around a size 6 or 7. Inside there’s a small engraving 'L.R.' and a tiny crescent moon stamp near the bottom edge. It’s in decent condition with just a few surface scratches from street wear. If anyone recognises it, please get in touch — I’d love to reunite it with its owner.
