Gold-tone bracelet with koi charm

I lost my gold-tone bracelet yesterday around 3pm near the Truman State University campus bookstore on Normal Avenue in Kirksville. It's a slim, 6-inch bracelet with a tiny koi fish charm and a small heart charm; the clasp has 'AH' engraved on it. There's a faint tarnish on the back of the koi, and the bracelet feels a bit loose on my wrist. It was a gift from my grandmother and means a lot to me—I'll be heartbroken if it's gone; please help me get it back if you found it.
