14K gold ring with emerald, lost in Gold Country

Yesterday around 3pm I realized I’d lost my 14K yellow gold ring with a tiny emerald centerpiece. It’s a size 6, and the band shows a few small nicks from daily wear; I think it slipped off during a quick walk along Main Street in Grass Valley, near the Empire Mine parking lot. The ring is a vintage-style bezel setting, and the inner band is engraved with 'PP'. It’s really sentimental to me because it was my grandmother's ring, and I’d be heartbroken if it doesn’t turn up. If you’ve seen anything matching, please reach out—I’m really hoping to get it back.
