Art Deco 14k White Gold Filigree Diamond Dinner Ring

This is a vintage Art Deco period dinner ring, likely dating from the 1920s to late 1930s. The ring is constructed of 14k white gold, featuring a prominent elongated navette or lozenge-shaped head. This central mounting is characterized by intricate openwork filigree, milgrain detailing, and geometric engraving consistent with early 20th-century craftsmanship. At the geometric center is a square-set round brilliant or transitional cut diamond, flanked by smaller accent diamonds integrated into the filigree pattern. The metal exhibits a bright, cool silver-tone finish typical of rhodium-plated white gold. Distinguishing features include the lace-like floral and geometric cutouts. Regarding condition, the ring shows light surface scratches and softening of the milgrain edges consistent with age and regular wear. The prongs appear stable, though a structural check for thinning on the underside of the shank is recommended. No personal inscriptions or maker's marks are visible in the provided image. The quality of the hand-pierced filigree indicates high-quality jewelry manufacturing from the mid-Art Deco era.
