Gold-tone bracelet with heart charm

I lost my gold-tone bracelet yesterday around 3pm near the Bullring on Broad Street in Birmingham. It's a slim, 6.5-inch bracelet with a small heart charm and a tiny letter 'A' engraved on the inside. The clasp is a tiny lobster clasp, and there’s a faint scratch along the back from where it bumped my phone case. It has sentimental value—was a gift from my mum, and I’m really hoping to get it back.
