Hi Thaskia,

I'm so sorry you experienced this. It is very rare for gold filled to turn green. Did the actually earring turn green or your skin? We include a care card in all orders. Were you able to try to clean the studs? If gold filled happens to change color it can be cleaned off. We recommend an old toothbrush or rag and warm water with dish soap. This usually does the trick. If that doesn't we highly recommend a polishing cloth called a 'sunshine cloth'. They work great for cleaning gold filled jewelry. Please let me know if that works and if not we would be more than happy to either replace or refund your studs for you.

Sincerely,
Michelle
