Vintage Native American Turquoise and Sterling Silver Ring

This is a vintage Southwest-style ring, likely of Navajo or Zuni origin, featuring a large, irregularly shaped blue turquoise cabochon as its centerpiece. The turquoise displays a vibrant sky-blue hue with dark brown and grey matrix inclusions, and it possesses a unique, undulating surface texture that suggests it was polished while following the natural contours of the raw stone. The stone is securely housed in a serrated or 'sawtooth' bezel. Surrounding the bezel is an ornate sterling silver frame characterized by traditional Navajo silversmithing techniques, including small silver droplets (raindrops), hand-stamped leaf motifs, and a scalloped outer border. The metal exhibits a significant dark patina within the recessed areas, which provides a high-contrast background that emphasizes the bright blue of the gemstone and the handcrafted details of the silverwork. The construction is robust, typical of mid-20th-century Native American jewelry (circa 1950s-1970s). Visible condition concerns include light surface oxidation on the silver and some environmental debris caught in the crevices of the setting, but the stone appears structurally sound without visible cracks. No maker's marks are visible in this view, which is common for authentic older pieces. The craftsmanship is high-quality, showing deliberate and skilled hand-tooling.
