Silver-tone bracelet with blue heart charm, lost in St. Louis

I was strolling through Citygarden near Market Street yesterday around 3pm when I realized my silver-tone bracelet was gone. It's a slim 6.5-inch chain with a small blue enamel heart charm and a tiny silver charm etched with my initials 'A.R.' on the inside of the clasp. The bracelet feels worn but in good condition, and it has a lot of sentimental value—it was a gift from my grandmother who passed away last year. If anyone finds it, I’d really appreciate getting it back; it means a lot to me.
