Pierced earrings, silver tone with purple -jewelry

Earrings are in excellent used condition and kept in a clean smoke free home. Silver tone hoops are 3/4 of a hoop, 3 textured lines down the front with 1 square faux purple stone toward the top. The stone has a gold tone edge. The inside has a design possibly just swirled lines- I couldn’t make anything out of it. The earring drop is about 5/8” - very pretty and look fancy. Not sure what the metal is. Brand unknown. #jewelry #pierced #earrings #silver-tone
