Sterling silver bracelet with turquoise bead, sentimental keepsake

I lost my sterling silver bracelet with a turquoise bead yesterday around 3pm. It's about 7 inches long, a bit oxidized from wear, and the tiny heart charm on the clasp is engraved with the initials 'M'. I was near the Aerial Lift Bridge along the Duluth Lakewalk, and it might have slipped off in the crowd. This Miscellaneous Jewellery piece has sentimental value—it's a gift from my grandmother—and I’d be incredibly grateful to have it back.
