Stunning craftsmanship on this sterling Native American Ring Measuring 1.46 in. x 1.07 in. Hallmarked A.R.P Augustine & Rosalie Pinto amazing silver smiths. Augustine and Rosalie Pinto were the last of the great Zuni Silversmiths who worked by hand without the use of electricity. They specialized in Mosaic Inlay… a style created in Zuni by Teddy Weahkee . Mosaic Inlay is much like a puzzle, inlaying one piece against another without using silver channels for support. As a result Mosaic Inlay is light weight and fragile. Augustine and Rosalie Pinto began producing jewelry in 1950’s and worked into the 1970’s.
