Vintage Light Pink Faux Pearls

Beautiful light pink knotted Pearl like closed necklace. 36” in length. Heavy weighs 6.7 ounces. Please see pics there are a few tiny black spots here and there on the necklace close to the drill hole. Overall good condition. I thought these were glazed over pearls, they are heavy and seem to be some kind of shell or pearl. They have the gritty feeling. To be safe being sold as faux
