Nickel Quality

Does anyone know the quality of gold and nickel composite jewelry?

I like costume jewelry, but I don’t want something that will deteriorate in a few days.

Maybe it means plated. I know that gold filled contains more gold and lasts longer than plated. For quality that will last, maybe you can consider vintage costume jewelry. I love vintage jewelry. I’m sooo into sterling these days too, because I think it will be worth more in the long run. With vintage, you will spend less and have a better quality piece.
