Found silver chain necklace with moonstone pendant

I found a silver-toned sterling chain necklace this afternoon around 3:15pm in the parking lot behind the Cherry Hill Mall on Route 38 in South Jersey. It’s about 18 inches long with a small oval pendant that features a moonstone center and tiny star engraving along the edge. The back of the pendant is engraved with the initials 'A.J.' and the chain shows a little wear but all links are intact. If this belongs to you, I’d be happy to return it—these things can mean a lot to someone.
