Celtic Cross Silvertone Post earrings

Hi! Up for sale is a lovely pair of Celtic Cross silvertone post earrings. I don't know what material they are actually made of as they were a gift—purchased in Scotland! In the images, there appears to be a little verdigris on them, but I didn't notice that while taking the pictures, for what that is worth. Also, one of the posts is a little wobbly, but I even pulled on it and it is not actually loose. Please feel free to ask question! Please see my closet for other new jewelry listings—I LOVE bundles! From a smoke-free, pet-free home, and I ship same or next day.
