Silver bracelet with heart charm, lost

I was at Lewiston Riverfront Park yesterday around 3pm when I realized my silver bracelet was gone from my wrist. It's a thin, dainty bracelet about 7 inches long, with a small heart charm and the letter 'A' etched near the clasp, and the clasp has a tiny scratch. The bracelet has sentimental value—it's from a handmade shop and was a gift from my sister who lives out of town. I last saw it near the pedestrian bridge on 2nd Street, close to the little cafe there, and I'm really hoping someone picked it up and kept it safe. If you found it, please reach out; I can describe the clasp and charm and I'd really appreciate getting it back.
