This 18" long necklace is made of an ombre of natural color pearls ranging in size from 7-12mm. The pearls include Chinese fresh water, Japan Akoya, Japan Kasumi, Tahitian and South Sea. In the center sits a solid 18k yellow gold cowrie shell and the clasp is a simple solid 18K yellow gold "S" hook. The necklace is light and works really well in a layered look. The cowrie shell can be worn in the center or slightly off to the side. ID#KDN3475/KDJ4000
