Lost gold ring with emerald in Jackson

Lost my gold ring yesterday around 3pm in Jackson. I was walking past Cornerstone Café on Main Street, just outside the Jackson Library, when a crowd jostled me and I realized it was gone. It's a slender 14k gold band, about 4mm wide, with a bezel-set emerald and an inside engraving that reads 'P.K. 97'. The ring has sentimental value—it was a gift from my grandmother—and I’d be so grateful to get it back.
