Both the Rainbow Moonstone and the Grey Moonstone in this bypass ring showcase the natural chatonanyce that we have come to know and love about Moonstone! Both stones are 9x11mm cabochons and the solid silver band is 8mm wide. This ring allows for some size adjusting due to the design. It was designed by Marianna and Richard and handmade by Balinese Artisans. The face is just over 3 /4" .
