New set of 3 Madewell necklaces in gold metal, seashell and beads

New without tag 3 Madewell necklaces 2 are from a set - the shell necklace and square link necklaces are part of a set but missing the original third necklace. The other necklace I just added to these two to make a set of three. Wear all together or separately. Mix and match for different options. Gold plated. Real shell. Necklaces range in length from 15 - 18” with 3” extenders.
