This great ring combines the beauty of the iridescent colorful Rainbow Shell with clean Sterling silver bead accents. The shell has been faceted to maximize the light reflections! The shell measures 16mm and the face of the ring is 1". The band has been left open in the back allowing you to adjust up to one ring size larger. Designed by Marianna and Richard and handmade by Balinese Artisans this is a great ring!
