This spinner ring is made from sterling silver and 14k gold-filled wire. The band which creates the base of this ring is made from .8 mm thick sterling silver sheet. I sawed out the band, shaped and hammered it to create large, shimmering vertical facets. The band is aproximately 1 cm wide and lightly polished. The center band is made from bead wire that has been hammered flat and given a brushed finish. The two 14k gold-filled bands that frame the center band have small facets created by hammering. All three bands spin freely and smoothly. The ring is extremely comfortable. I've flared the edges only enough to keep the bands on the ring. All edges are filled and sanded smooth. This is a great ring to wear on your middle or fore finger so you can easily spin the bands with your thumb. Made to order in your size. I recommend ordering a full size larger in this style.
