Gold-tone necklace with heart pendant found

I found a gold-tone necklace this afternoon around 2:25pm in the parking lot behind The Gardens Mall in Palm Beach Gardens, Palm Beach County. It's an 18-inch curb chain with a small teardrop pendant, and there's a tiny heart charm engraved with the name 'Mira' on the back. The metal shows a few light scratches but overall it's shiny and in decent condition, just a bit worn near the clasp. If you recognize it, tell me details about the engraving or where you might have worn it, and I’ll help return it to its owner.
