Vintage Navajo Hopi Katsina / Dancer Sterling Silver Pin-Brooch

This is a vintage Southwestern Native American style pin-brooch, likely of Navajo or Hopi origin, depicting a ceremonial dancer or Katsina figure in a dynamic, active pose. The piece is constructed from cast and hand-stamped sterling silver, featuring a central figure with a pointed headdress and a horizontal bar element across the torso. The piece exhibits heavy tarnish and a distinctive green oxidation (verdigris) concentrated around the head and upper body, indicating prolonged exposure to moisture and the presence of copper in the alloy. This thick patina suggests significant age, likely mid-20th century (circa 1940s-1960s). The anatomical rendering is stylized with angular lines and V-shaped stamping on the chest. While no visible maker's mark or '925' hallmark is seen in the top-down view, the craftsmanship shows traditional silversmithing techniques used in the American Southwest. The condition shows moderate surface wear and heavy oxidative residues that could be professionally cleaned or left to preserve the antique character. The legs are depicted in a staggered movement, adding a sense of ritualistic motion to the jewelry.
