It's a single earring! I purchased it from the online store last year. I've used it a few times and then stored it. There are no noticeable scratches, but please understand that it is a used item and may have some tarnish typical of jewelry. Discoloration can be cleaned with a jewelry cloth. Material: SILVER925 + K18YG plating Size: Hoop Diameter: 19mm Wire diameter: 2mm Color: Gold
