This 18" long necklace is made of natural color butter cream Japanese akoya pearls ranging in size from 7-8.5mm. At the center is a conch shell I found on the beach myself.. filled with tiny white Chinese fresh water pearls. The clasp is a gold plated fold over .. very secure and easy to use. This is a lovely soft piece that plays well with others. ID#KDN3116/KDJ2800
