Vintage/Antique Filigree Ring with Three Stones

The item is a vintage-style ring, likely made of a base metal such as sterling silver or a white gold alloy, given its tarnished appearance with a dull, greyish sheen and hints of a warmer, possibly brassy or oxidized undertone in recesses. The ring features an elongated oval or navette-shaped head, typical of Art Deco or Edwardian designs, approximately 15-20mm in length. The setting is adorned with three prominently displayed, round, colorless stones, with the central stone appearing slightly larger than the two flanking ones. These stones are cut in a brilliant or rose-cut style, characterized by numerous facets that catch the light, though their exact nature (diamond, cubic zirconia, or paste/glass) cannot be definitively determined from the image. The metalwork around the stones is intricately detailed, featuring open filigree or pierced designs that give the ring a delicate, airy feel. The filigree includes scrolling motifs and potentially small beadwork (milgrain) along the edges of the settings or the band itself. The band appears to be a consistent width, or possibly tapering slightly towards the back, and shows signs of wear consistent with age, including surface scratches and a noticeable patina or oxidation in the recessed areas of the filigree, which enhances the contrast of the design. No clear maker's marks or hallmarks are visible in the provided image. The overall impression is one of an older, possibly antique or vintage piece, reflecting the craftsmanship of the early to mid-20th century. The quality of the setting appears to be good, with stones securely held, and the intricate design points to a piece with careful attention to detail in its manufacture.
