Made with eight (8) pieces of turquoise and four (4) pieces of yellow mother of pearl mostly stone to stone inlaid in a raised dome shape. It has two wires that curve in the center separating the setting into four sections. Mounted to a square face cast band. The ring face measures 3/4" by 5/8" and weighs 13.1 grams. It's a tight size 12 and could fit a 11 3/4 sized finger. It is unsigned sterling or coin silver. Most likely Zuni made. $84.95
