Silver Pandora necklace with compass pendant

I lost my silver Pandora necklace yesterday around 3:15pm outside the Shinola store on Woodward Ave near Campus Martius Park in downtown Detroit. It's a 16-inch silver-tone chain with a tiny compass pendant and a small turquoise bead; the clasp is a bit stiff but still works. The pendant has the initials 'PJ' engraved on the back and there’s a faint scratch on the chain near the clasp. It was a gift from my grandmother and means a lot to me, so I’m really hoping to get it back. If anyone found it, please let me know—I'm in the Detroit Metro area and I’d be so grateful.
