Lydell N.Y.C 7 strand waterfall bib necklace

Lydell N.Y.C 7 strand waterfall bib necklace I inherited over 1000 pieces of vintage and fashion jewelry. I am not a jewelry expert. I put them in pretty matching bundles for fast listing. All closures close and no missing stones unless stated in listing. Minimal wear on some pieces. After all they are pre-owned. Unless item is marked I do not know specifics about brand or material.
