Vintage Art Nouveau Style Silver Solitaire Ring with Cubic Zirconia

This is a vintage-style solitaire ring featuring a bypass shank design with ornate foliate or scrollwork motifs reminiscent of the Art Nouveau period. The band is crafted from a silver-toned metal, likely sterling silver given the visible '925' hallmark on the interior shank. The ring features a single, round-cut colorless stone, which appears to be a cubic zirconia or glass paste based on the high dispersion and lack of complex natural inclusions visible in the light. The setting is partially enclosed by the decorative metal swirls, which provide a flowing, asymmetrical aesthetic typical of mid-20th-century revival pieces. The metal displays a heavy grayish patina and surface oxidation particularly in the recessed areas of the design, which underscores its age. The stone is secured in a bezel-like or modified prong setting, showing some surface grime and minor scuffing on the facets. The overall craftsmanship suggests a mass-produced but decorative jewelry item, likely dating from the 1970s to the 1990s. The ring shows signs of moderate wear, including minor surface scratches on the band consistent with regular use.
