Hello, I have the mini Love earrings in Rose Gold. They have a solid back. Since I purchased them, green/ black rust-like material is coming out of the back and tainting my earhole, as well as the clasp itself. The rust is coming from the hole as well as from the metal parts of the clasp. Is this what you are experiencing?
If yes, I have been to Cartier 2 times about this issue. Both times, unfortunately, they just told me to clean them better. The second time an SA told me that this is a known problem with RG earrings.
I did notice if you take them out when you shower and at night they do not oxidate that much..
