This is a signature design by Navajo smithing couple Happy Piasso and Rudy Willie which they execute in making both pendants and rings. They always use the finest grade of stones in these pieces which feature a border formed by starred buttons.
This is set with a thick, deep green egg-shaped stone of natural, untreated Royston turquoise from Nevada. The stone is set in a smooth bezel wrapped with twist wire which, in turn, is encircled by starred buttons which form the border of the ring face. The shank is of uniform width and is marked by stripes of grooved stampwork.
Hallmarked H. Piasso and stamped Sterling inside the shank.
