Vintage Filigree White Opal or Druzy Ring

This is a vintage statement ring featuring a large, oval-shaped central stone that appears to be a white opal with significant texture or potentially a white druzy quartz. The stone exhibits a shimmering, crystalline play of white and cream hues and is secured in a multi-pronged setting. It is surrounded by an elaborate, openwork metal halo in a scalloped, filigree style. The metalwork is a yellow gold-tone, likely gold-filled or high-quality costume plating, adorned with decorative bead or 'granulation' accents at the peaks of the scalloped edges. The overall aesthetic is characteristic of a mid-20th-century revival style, specifically referencing Victorian or Art Nouveau designs roughly from the 1950s to 1970s. The metal shows a light aged patina, particularly in the deeper recessed areas of the filigree, which adds contrast and depth to the design. No visible fractures are present on the stone, though there is minor surface wear consistent with age. The craftsmanship is intricate, pointing to a well-manufactured piece of vintage costume or semi-fine jewelry.
