Vintage Filigree Marquise-Cut Gemstone Heirloom Ring

This is a vintage heirloom cocktail ring featuring a prominent marquise-cut central gemstone, likely a pale yellow citrine or light-colored quartz, though precise mineral identification requires testing. The stone is vertically set within an ornate, wide-tapered band. The ring is crafted in a silver-toned metal, possibly sterling silver or white gold, characterized by intricate openwork filigree and scroll motifs that reflect Art Nouveau or late Victorian stylistic influences. The shoulders are wide and decorated with beaded milgrain-style borders and symmetrical swirling cutouts that provide a significant presence on the finger while maintaining a delicate, feminine aesthetic. The construction suggests a mid-20th-century vintage production, possibly a revival piece. Regarding condition, there is visible surface wear to the metal and minor scratching on the gemstone facets, consistent with age and frequent use. A dark patina is present within the recessed areas of the filigree, which enhances the visual depth of the design. No immediate maker's marks are visible in the photograph, but they would typically be located on the interior of the shank. The overall craftsmanship shows good attention to detail in the symmetry of the openwork and the secure prong setting of the center stone.
