Silver heart locket with photo - lost

I lost my silver heart-shaped locket yesterday around 3pm outside the Fargo Theatre on Broadway in downtown Fargo. It's a small sterling-silver locket, about 1 inch tall, with a delicate floral engraving on the front and a tiny photo of my grandmother tucked inside. There's no visible brand mark—it looks like a simple vintage piece, and the chain is a thin zig-zag link; the lid edge is slightly loose after I dropped it near the curb. This locket means the world to me—it was a gift from my mom, and it holds a photo of someone I love. If anyone found it, please reach out; I’d be so grateful to get it back.
