Gold-tone heart necklace with initials engraving

I found a gold-tone necklace this afternoon outside the Fox Theatre on Peachtree Street, near the intersection with 7th. It's a delicate 18-inch chain with a heart pendant about an inch tall, and the metal has a soft shimmer that catches the light. On the back of the pendant there's a tiny engraving with the initials 'A.R.'—a detail I thought could really help the owner identify it. The clasp is still springy, and the chain looks gently worn but clean. If this belongs to someone, I’d love to get it back to you; it clearly has meaning and I’m happy to meet up to return it.
