Vintage shell earrings with posts

Vintage white iridescent shell earrings, with posts. Shown with a quarter for scale in the 3rd pic. Purchased at a flea market in the late 90s, not sure when they originated. They remind me of guitar picks and get a ton of compliments. Perfect if you want some delicate dangle but don’t want heavy earrings that will pull on your lobes. One of the earrings has a little chip/divot but it’s the natural surface of the shell used, I think, and not an imperfection. Shown in the photos. #vintage #summer #beachy #preppy #boho #mermaid
