Vintage black necklace with a bib of iridescent beads

Stunning and beautiful Vintage black necklace with a bib of clear, black, silver iridescent and Smokey gray beads. What a statement piece. No signs of wear and the lobster clasp looks new.It is a fairly heavy piece. Measures 10 to 11 inches in length with a bib that is 2 1/4 inches wide. See pictures for measurements. After 2 hours of looking I see no missing beads. However, keep in mind this is vintage and yes I'm vintage too. I try my best to describe in detail and show in pictures the piece and the details. What a beautiful gift or a wonderful addition to any collection. It is unbranded as I find no marks or signature on the piece. Reference: Box 5
