Edwardian Style Marquise-Cut Filigree Ring

This is a white-tone cocktail or engagement-style ring, likely crafted from sterling silver or white gold, featuring an intricate openwork filigree mounting. The central focus is a marquise-cut colorless stone, which appears to be a cubic zirconia or a white sapphire based on its clarity and luster, though high-quality diamond is possible. The stone is secured in a low-profile multi-prong setting integrated into the decorative gallery. The metalwork displays delicate scrollwork and geometric patterns characteristic of the Edwardian (1901-1915) or Art Deco eras, or a high-quality mid-to-late 20th-century revival. The filigree extends down the shoulders of the band, creating a light, airy aesthetic. While the image does not clearly show interior hallmarks, the craftsmanship suggests a cast production with hand-finished details. The condition appears fair to good; there is visible tarnishing or patina in the recessed areas of the filigree, and some minor surface abrasions are consistent with age and wear. The shank appears to be somewhat thin at the base, which may indicate long-term use. No significant chip or fracture is visible on the crown of the stone from this angle.
