I have no idea what happened! I baredly just noticed this today. Not sure if it’s been like that or it just happened. I don’t remember it being like this. Has something like this ever happened to your platinum ring? I’m usually careful with my hands.. So I don’t think I banged it hard or anything. How can this be fixed?! Would they use platinum metal to add on or some other type of metal? I’m so sad about this. I don’t want them burning my diamond trying to add platinum because I heard the melting point of platinum is high enough to burn a diamond.
