Lost & found necklaces & chains in South Florida

Gold-tone necklace with sapphire heart pendant

I lost my gold-tone necklace yesterday around 3pm near the Lincoln Road Mall in Miami Beach, South Florida. It's an 18-inch delicate chain with a small sapphire heart pendant; the pendant has a tiny engraving on the back—'LR'—and the lobster clasp shows a bit of wear. The chain is in decent condition, but the spring is a bit stiff and the pendant catches the sun when it tilts just right. This necklace is sentimental; it was a gift from my grandmother who passed away last year, and I really need it back. If anyone found it, please reach out—I'd be grateful to arrange a meetup around Bayside Marketplace or Lincoln Road to pick it up.
