This contemporary ring features a beautiful square piece of yellow spiny oyster shell with purple striations running through it. It was set in heavy sterling silver by C. Willie of Tohajiilee, New Mexico. It is a size 7.5 - 8 with beautiful chisel work on the sides of the setting and a flat top so the ring, though of heavy silver, will not flop around on your finger. This ring is 1-1/4" square and the band is cast with a triangle design on the sides. The piece is hallmarked.
