Gold-tone bracelet with heart charm

I lost my gold-tone bracelet yesterday around 3pm near the Riverwalk by the Diamond Jo Casino on Main Street in Dubuque. It's a slender 7-inch gold-tone chain with a small heart charm, and on the back of the charm there's the initials 'A.M.' engraved and a tiny scratch on the chain. It's a small piece of miscellaneous jewellery, and it wasn't new—it's a gently worn piece with a bit of tarnish around the clasp. It means a lot to me because it was a gift from my grandmother, and I really need it back. If you found it, email me at [email protected] and I'll recognize the piece right away.
