Ella Cowboy is noted for her very fine inlays. She handcrafts this single band in many different variety of stones. This ring is made from Sterling Silver and Purple Lab Opal and the stone in the center is a round shaped CZ. Which looks like a perfect diamond. Ella is from the Navajo Nation. I have a size 10. Be sure that you are a size 10 as this ring  can not be sized because of the inlays. The widest part of the ring is 1/4" and tapers down slightly. I also pictured the different varieties of rings and sizes she makes in this same style however, you must purchase them in a different listing so view those pictures in my store. The inlays go half way around the ring. The back of the ring is a smooth shiny silver. "SIGNED."   The dimensions of the ring is 1/4"  at the widest and tapers down slightly.   Our jewelry is guaranteed "NATIVE AMERICAN MADE." Your item comes with a "CERTIFICATE OF AUTHENTICITY." "NEW." We package our jewelry in a nice "GIFT BOX."
