Statement Necklace 18" Choker Mother of Pearl Mosaic Pendant

This is a statement necklace with Mother of Pearl mosaic large circle in the center. The choker necklace measures approx 18" when open and laid flat. There are several white cords that have the 2.5" mother of pearl circle in the middle. The pendant is kept on with 2 seed bead loops. ***The mother of pearl mosaic pieces are put onto a backing, reminds me of coconut shell, in the back to add strength to the shells. Source unknown, metal unknown. The silvertone closure is a lobster claw. The White cords show some use and you might want to wash them.
