Obviously Southwest inspired, these earrings feature a sawtooth set stone resembling lapis lazuli  shadow boxed by typical southwestern ornamentation. These earrings are in good working order with intact patina. There are signs of tarnish and wear located on the back of the earrings. I would recommend having these professionally cleaned by someone who knows vintage jewelry. These are signed Carviso. They do not have the typical E. or W. first initial but they are stamped sterling. These may be from the New Mexico tribe of Navajo jewelers but this has not be authenticated.
