Sterling Silver backing, post is stainless steel on some. New earrings are all sterling silver.
*All earrings are definitely one of a kind. I hand pick these beautiful stones to compliment each other within the pair. I do my best to update pictures and make them current, but you may find variations with the ones you receive and the picture online due to the one-of-a-kind nature of these. Just know they were hand picked and chosen for you!
