Silver hoop earrings with heart charm

I lost my silver hoop earrings yesterday around 3pm near the Starbucks on The Hayes in Cardiff city centre. They're small, about 1.2 cm in diameter, silver-plated hoops with a tiny heart charm on one hoop, and the back has an engraving 'LP'. They were a gift from my grandmother and carry sentimental value; I really hope someone picked them up. If found, I'd be incredibly grateful to get them back via the app.
