Gold-tone heart pendant necklace, sentimental gift

I lost my gold-tone heart pendant necklace yesterday around 6pm near Forsyth Park's north gate on Drayton Street in Savannah. It's a delicate 18-inch cable chain with a small hollow heart pendant, front engraved with 'Mom' and a tiny sapphire bead at the top. The back has a faint scratch along the chain near the clasp, and the clasp is a standard spring ring. It was a gift from my grandmother and means the world to me; I’m really hoping it turned up somewhere nearby. If you happened to find it, I’d be forever grateful—I can meet at a cafe near Chippewa Square to pick it up.
