Necklace bundle of 3 pieces.

Necklace bundle of 3 pieces. Large cameo on black cord; mother of pearl open-faced shell on grey and black beads and black, blue, white tiny beads ( I don't know anything about this except a friend brought back from Africa). Large cameo looks so elegant and the mother of pearl covers a large open neckline area or plain sweater. All are in like-new condition.
