Vintage Native American Sterling Silver and Green Turquoise Ring

This is a vintage Southwest-style ring, likely of Navajo or Zuni origin, featuring a large, irregularly shaped cabochon of green turquoise. The stone exhibits a vibrant forest green hue with a distinctive brown and tan matrix, suggesting it may have come from a Nevada-based mine such as Royston or Carico Lake. The turquoise is securely housed in a hand-stamped serrated bezel, which is a hallmark of traditional Native American silversmithing. Surrounding the stone is a shaped sterling silver shadowbox frame decorated with applied silver raindrops (beads) and a fine wire border. The metal shows a dark, heavy oxidation (patina) in the recessed areas, which provides excellent contrast and highlights the handcrafted detail. The construction appears to be solid and typical of mid-20th-century craftsmanship. While no maker's mark or hallmark is visible from this angle, the style is consistent with 1960s-1970s artisanal production. There is minor surface wear on the stone and some mild scuffing on the silver, consistent with age and regular use, but no significant cracks or repairs are evident.
