Carico Lake Turquoise Mosaic Inlay Ring by Rita Dawes, Navajo, Size 9

Rita Dawes, a Navajo silversmith, hand-set this large oval mosaic inlay in sterling silver with a stamped bezel surround. Carico Lake turquoise comes from the Carico Lake mine in Lander County, Nevada, and is immediately recognizable by its vivid apple-green color — a result of zinc replacing copper in the stone's mineral composition. It is one of the rarest and most sought-after turquoise varieties in Native American jewelry. The mosaic inlay technique involves precisely cutting and fitting stone pieces flush into a silver setting. Ring size 9. Available exclusively through Turquoise Mustang.
