This is a beautiful 5mm black coco bead necklace with white puka shell accents. The necklace closes with a silver-toned barrel lock. Coco beads come from coco trees that grow in abundance and are an eco-friendly material choice. The white puka shell accents make a great contrast with the coco beads and highlights the natural appeal of the coco wood. A great necklace for men, women and teens! Perfect to wear to the beach to to just look like you're on your way to the beach!
