Vintage 1970s Southwestern Turquoise and Sterling Silver Statement Ring

This is a vintage Southwestern-style statement ring, likely of Navajo or Zuni origin, dating to the 1970s. The ring features a large, freeform triangular-cut turquoise cabochon as its central focus. The turquoise exhibits a vibrant robin's-egg blue hue with a subtle brown and tan host-rock matrix, suggesting it may originate from a classic American mine such as Kingman or Royston. The stone is securely held in a hand-burnished serrated bezel setting, which is typical of mid-to-late 20th-century artisanal silverwork. Encircling the base of the bezel is a decorative twisted silver wire (often referred to as 'rope' detail), which provides texture and visual depth to the piece. The overall construction appears robust, with the setting mounted on a silver shank that is likely split into a multi-wire design at the shoulders to support the large scale of the face. Regarding condition, the turquoise shows a polished luster with some natural surface pits inherent to the stone. The silver shows a moderate layer of dark oxidation (patina) concentrated in the recessed areas of the twisted wire and bezel, which is a desirable indicator of age. No visible cracks are seen in the stone from this angle. While hallmarks are not visible in the photograph, rings of this period and style are typically crafted from .925 sterling silver.
