Art Deco Filigree Ring with Rectangular Red Stone

This is an Art Deco style filigree ring featuring a prominent rectangular, step-cut red gemstone. The gemstone exhibits a vibrant reddish-pink hue and appears to be either a synthetic ruby or a deep red garnet, possibly even a high-quality glass. It is set in a bezel or semi-bezel setting within a highly decorative white metal mounting, likely sterling silver or white gold, given the intricate filigree work typical of the Art Deco period. The shoulders and gallery of the ring are adorned with delicate openwork filigree designs, characterized by geometric patterns and fine scrollwork, which are hallmarks of the 1920s-1930s aesthetic. The craftsmanship suggests a combination of cast and hand-finished techniques, with precise cutouts forming the intricate patterns. Visible condition issues include some minor surface wear on the metal, consistent with age and use. There may be slight tarnishing in the crevices of the filigree, contributing to a desirable patina. The stone appears to be securely set, and there are no immediately obvious chips or cracks, though a closer inspection would be required to confirm its integrity. The overall design emphasizes elegance and geometric symmetry. While no specific maker's marks or signatures are visible in the provided image, such intricate work often indicates a higher quality piece from its era. The ring's bold center stone contrasted with its delicate setting showcases the typical Art Deco preference for both glamour and refined detail, making it a compelling piece of vintage jewelry.
