Found silver pendant necklace near Monument Circle

I found this silver pendant necklace this afternoon around 3:15pm near the fountain at Monument Circle, downtown Indianapolis. It's an 18-inch sterling silver chain with a small heart-shaped pendant that has a pale blue enamel center and tiny 'A.J.' initials engraved on the back. The clasp is a sturdy lobster claw and the chain shows minor wear, but the piece is otherwise in good condition. If the owner recognizes it, we can figure out a safe way to reunite it—I know how much a piece like this can mean.
