I wish I knew for sure but I don't. They are very pretty and they shine like my wedding ring from the 40's and my ring is real. Sorry I don't have more info. for you.
I own 2 of these exact same sets, with the earrings that match! They are made by Avon and are made of a solid sturdy metal, not sure what metal, but Avon makes awesome jewelry! Whomever wins these will not be disappointed! I may have to bid to win so I'll have backups in case mine ever break! LOL Thank you for sharing these quality pieces! ❤️
