Gold-plated hoop earrings with sapphire drop

Yesterday around 3pm I realized my gold-plated hoop earrings with a tiny sapphire drop were missing. I was by the Starbucks on Corporation Street near Grand Central in Birmingham, wandering between the entrance and the bus stop when they slipped out. The hoops are about 2 cm in diameter, gold-toned, with a small sapphire teardrop that catches the light. One earring has a faint scratch on the back, and the stone has a slightly greener hue in certain angles. They were a gift from my grandmother, so they mean a lot to me and I’d really appreciate getting them back if someone found them.
