14k gold emerald ring with M.K. engraving

I lost my 14k gold ring yesterday around 3pm near the Monroe Public Library on Main Street. It’s a slim, slightly worn band with a small emerald set in a simple bezel, about a standard finger size. There’s an engraving inside the band: 'M.K.' and a tiny scratch near the 7 o'clock position—easy to spot if you look closely. It’s sentimental; it was a gift from my grandmother and I really need it back. If you found it, please drop it off at the Monroe Library desk or the police lobby, or message me here. It’s in good condition besides the scratch, and I’m hoping a kind person did the right thing.
