Gold ring with emerald, engraved inside, sentimental value

I lost my gold ring yesterday around 3pm near the Benton Convention Center on Trade Street in Winston-Salem. It's a 14k gold ring, size 6, with a small emerald set in a delicate leaf design; unbranded, no obvious hallmarks. The inside is engraved with 'PK 2010' and there's a tiny surface scratch along the outer edge from wear. It was a gift from my grandmother and has sentimental value—hard to replace. I really need it back, so if anyone found it somewhere between the Convention Center and Old Salem, please let me know. I'd be forever grateful.
