Lost & found earrings in Chattanooga

Gold-tone hoops with emerald drop, engraved AS

I lost my gold-tone hoop earrings with a tiny emerald drop yesterday around 3pm. I was walking along Market Street by the Tennessee Aquarium and I think I dropped them while heading toward the Walnut Street Bridge; they could have fallen on the riverfront near Coolidge Park. They're small, about 1 cm hoops, gold-tone plated, with a delicate emerald charm on one hoop. The back of one earring has a tiny engraving 'AS' and the clasp shows a faint scratch. They were a gift from my grandmother, so they're really sentimental to me and I'd be grateful to get them back if anyone finds them around Chattanooga.
