Your cat called and told me that you need these earrings 😺 They are made of sterling silver and are stamped 925. The earrings have a pin earring back for pierced ears. Please see photos for size context. ***PLEASE READ*** I have one pair of these left and noticed that one of the moons is slightly less circular than the other. I've put these on a "green sale" because I believe in reducing waste and would feel awful tossing these due to a slight imperfection. However, I also wanted to be honest about their appearance. Although this last pair is not "perfect" I know that someone out there can still love them and wear them well. See 4th to last photo for condition.
