Gold-tone necklace with heart pendant

I lost my gold-tone necklace yesterday around 3pm near the Whole Foods Market on Airport Boulevard in Mobile. It's an 18-inch delicate chain with a small heart pendant. The brand is Aurelia, and the pendant has a tiny engraving on the back with the initials 'M.P.' and a tiny turquoise bead near the clasp. The chain is slightly tarnished from wear and the pendant shows a few micro-scratches from daily use. It means a lot to me because it was a gift from my grandmother, and I’m really hoping to get it back.
