Authentic Chanel Pearl Crystal CC Charms Stud Earrings

These are obviously used but 100% authentic purchased from the Chanel boutique in Paris, France in 2016. There is one missing Pearl which I have circled in blue in one of the images. There is some black debris (I honestly don’t know where this came from - maybe just tarnished from sitting in the box for so long) which I believe (but cannot guarantee) you can get polished/cleaned (I am not doing that myself because I am not a professional and do not want to damage the earrings).
