Faceted rose stone necklace and pendant

I’m not very gemstone savvy but I was told this is a faceted rose quartz stone pendant. Correct me if wrong and I will adjust the post. The chain feels like some sort of costume Jewelry metal. Either way this is a beautiful long pendant necklace (it’s got weight to it). I’ve loved it and enjoyed it and am ready to connect with a new owner to enjoy. Chain hangs to 16”
