Gold-tone heart pendant necklace, 18-inch chain

I lost my gold-tone heart pendant necklace yesterday around 3pm near the Starbucks on Main Street in downtown Mattoon. It's an 18-inch gold-tone rope chain with a tiny heart pendant; the back is engraved with an 'M'. The clasp is a bit stiff, but it still hooks fine. It was a gift from my grandmother, and it means a lot to me, so I’m really hoping someone found it. If you’ve seen it or picked it up, please reach out—I’d be forever grateful to have it back.
