Silver-tone necklace with pearl pendant

I found a small silver-tone necklace this afternoon around 2:45pm near Public Square in Wilkes-Barre. It's about an 18-inch chain with a tiny freshwater pearl pendant and a little heart charm engraved with 'M' on the back. The chain has a few surface scratches but the pearl is pristine, and it looks like it's been cared for. It may have sentimental value to whoever lost it, and I’d love to return it to its owner if you claim it.
