Gold-tone bracelet with M initial charm

I lost my gold-tone bracelet yesterday around 3pm near the San Marcos Public Library on East Hopkins Street. It's a slim 7-inch chain with an engraved M on the clasp and a tiny emerald-green bead charm. The bracelet is a bit worn and has a small scratch along the back, but it's still meaningful to me—my grandmother gave it to me, and I really need it back.
