Our Vintage Coral Clip On Earrings are the perfect accessory for summer. The detailed sterling silver exhibits light patina but could be polished if your prefer a shiny finish. Crafted in the form of petals they meet at the center to display a gorgeous bezel set piece of coral. They remind me of sunflowers. This pair is an estate find that has been very well cared for. I have noticed no issues. I am not sure if these are Native American.
