2 Vintage shell necklaces

The one on the right is a Really beautiful vintage polished shell pieces necklace. The shells towards the center are larger than the ones to the side which gives it a pleasing symmetrical design. It closes with a secure twist clasp. In perfect condition. The one on the left closes with the same type of twist clasp and has really pretty shells too. They are interspersed with little pearl-colored beads and the end part is brown beads. In good condition although some of the shells twist a bit.
