Vintage 18k White Gold Three-Stone Art Deco Diamond Ring

This is a vintage three-stone ring crafted in 18k white gold, exhibiting strong Art Deco design characteristics likely dating from the 1920s to 1940s. The central display features three round brilliant or transitional cut diamonds set horizontally in square box-style frames with a milgrain border, creating a clean, geometric silhouette typical of the period. The shoulders of the ring are highly decorative, featuring a vertical fluted or 'staircase' motif that leads into a foliate engraved pattern on the shank. The craftsmanship shows high-quality metalwork with intricate filigree-style engraving along the band. In terms of condition, the ring shows age-appropriate wear with a subtle patina on the white gold surface. The prongs appear secure, though the milgrain detailing shows slight softening from decades of wear. The diamonds appear clear with a bright face-up presence, though a professional cleaning and loupe inspection would be required to verify clarity grades. The piece is distinguished by its architectural shoulders and the contrast between the sharp geometric settings and the organic leaf engravings on the band.
