Sterling silver necklace with heart pendant and sapphire

Hey, I lost my sterling silver necklace yesterday around 3pm, right outside Glasgow Central Station on Gordon Street. It's an 18-inch chain with a tiny heart pendant, and a small sapphire set in the middle. On the back there's a faint engraving of the initials L.J., and the chain has a few micro-scratches but it's otherwise intact. It means a lot to me because it was my grandmother's, and I’ve worn it every day since she passed—if anyone found it, I’d be so grateful to get it back.
