This is a show stopper necklace, fabulous and fun! The black beads are hard resin or plastic. The black and gold-tone beads are dramatically accented by triangular slices of abalone. The large luminous pendant measures 3 x 3 3/4" and the necklace measures 24” long, not including the pendant. Everything about this piece is in good vintage condition with no issues. Circa 1960s – 1970s
