BeBold 2ct Engagement Ring for Women Marquise Cut Moissanite Dual Halo Vintage Inspired White Gold Plated

This is such a beautiful ring! I love it so much. But I am concerned. It was supposed to be 14k white gold, but it is not stamped. No stamp of any kind. If I need to have it resized at some point no jewler I know would touch it. Can you provide some kind of certification as proof that it is a quality metal. Thank you for your time & effort.Raylinn
