Gold pendant necklace with pearl charm

I lost my gold pendant necklace yesterday around 3pm near the Kenosha Public Market on 2nd Ave by the fountain. It’s a 14k gold chain, about 18 inches long, with a small heart-shaped pendant that holds a single freshwater pearl. The back is engraved with 'A.R.' and the clasp has a tiny scratch I can recognize. It was a gift from my grandmother and means a lot to me—really sentimental and I’m hoping someone picked it up by accident. If you found it, I’d be incredibly grateful to get it back.
