Gold-tone bracelet with koi charm

I lost my gold-tone bracelet yesterday around 3pm near Campus Martius Park on Woodward Ave in the Detroit Metro area. It's a slim 7-inch bracelet with a small koi fish charm in blue and orange enamel, and the finish is lightly tarnished from daily wear. On the inside of the clasp there's a tiny engraving 'A.M.' and a faint dent near the charm that's easy to spot. It means a lot to me—my grandmother gave it to me last year, and I wear it almost every day. If anyone finds it, please drop me a note; I’d really appreciate getting it back.
