I am in love with metal factory ! many sites promise their items will not turn green or rust and all do. But this company is amazing <3 I have bought many rings from here and I am very pleased. All of my friends who I have gifted to, say they love the ring. The fit is perfect , the colors are bright and amazing, it stays just as gorgeous as the first day you receive it. In the case of these earrings its beautiful. I'm so happy for Metal factory
