Silver bracelet with heart charm, lost near Bullring

I lost my silver bracelet yesterday around 3pm. It's a slender 6 cm silver-tone bracelet with a tiny heart charm engraved with the initial 'M' and a small lobster clasp. I was at the Bullring shopping centre, near the Selfridges entrance on Corporation Street and the escalators by Waterstones; I think it slipped off in the crowd. It's in decent condition aside from a faint scratch on the clasp, and it has huge sentimental value because it was a gift from my grandmother that I wore every day. I really need it back—if anyone found it, please message me; I can offer a small reward and I'd be incredibly grateful.
