Found gold-tone hoop earrings with pearl charm

I found a pair of gold-tone hoop earrings with a tiny freshwater pearl charm this afternoon around 5:45pm. They were sitting on the sidewalk outside the Carnegie Library of Pittsburgh on Forbes Avenue in Oakland, near Schenley Plaza. The hoops are about 2 cm in diameter, gold-tone with a subtle hammered texture on one hoop, and the charm is a small white freshwater pearl about 4-5 mm. The posts show a bit of tarnish, and the overall condition is gently worn but intact. I’d love to get them back to their rightful owner—if these sound like yours, tell me the last place you wore them or describe the hammer detail to confirm.
