Gold chain necklace with sapphire pendant

I lost my gold chain necklace yesterday around 3pm near the Publix on West Main Street in Dothan. It's an 18-inch, 14k gold-plated chain with a small heart-shaped sapphire pendant. The clasp is engraved with a 'P' and the chain has a few micro-scratches from daily wear. It means a lot to me because it was a gift from my grandmother, and I was really hoping to find it. If anyone picked it up, please message me—I’ll be forever grateful.
