This adjustable size 7-8 sterling silver ring is really nice! The band is about 2 mm wide. The volleyball part is 12 mm tall and 12 mm wide. DO NOT bend the ring to size when off your finger, do not try and make a size smaller than a 7, and do not size it more than the once, it will break. Once it is the size you need do not bend it anymore. Take great care will adjusting the ring because silver will break.
