Vintage Southwestern Navette Turquoise and Silver Ring

This is a vintage Southwestern-style statement ring featuring a long, navette-shaped (marquise or almond-shaped) turquoise stone. The stone is a vibrant sky-blue hue with a distinct dark brown and black spiderweb matrix running diagonally across its surface, suggesting it may be sourced from a mine like Royston or Kingman. The turquoise is set within a smooth bezel, which is then surrounded by an ornate, oxidized silver frame. This frame features scrollwork, open filigree details, and small ball accents (granulation) that give it a substantial, handcrafted appearance typical of mid-20th-century Native American or Southwestern artisan jewelry. The silver exhibits a heavy dark patina, particularly in the recessed areas of the filigree, emphasizing the depth of the metalwork. The item shows signs of age-appropriate wear, including minor surface scratches on the stone and tarnishing on the metal. The overall construction indicates a piece from approximately the 1960s or 1970s, characterized by the 'Fred Harvey era' or boho-revival aesthetic. While no hallmark is visible in the photograph, the quality of the stone setting and the weight of the silver frame suggest a skilled maker.
