Slim silver bracelet with turquoise bead charm

I lost my slim silver bracelet yesterday around 3pm. It's a 6-inch silver chain with a tiny turquoise bead charm and a heart engraving on the inside that reads MG. The clasp is a small lobster clasp, a bit worn. I usually wear it every day; it has sentimental value because it was a gift from my grandmother. I was walking near the Leeds Corn Exchange on Call Lane, just off Briggate, when I think it slipped off while I ducked into a cafe. If anyone found it, please let me know. I'd really appreciate getting it back.
