1940s 5.93 Carat Emerald and Old-Cut Diamond Cluster Ring in 18K Gold and Platinum

Dating to the 1940s, this emerald and diamond cluster ring is centred on an elongated rectangular step-cut Colombian emerald of approximately 5.93 carats. The stone has a vivid, well-balanced green with visible jardin beneath its broad table. As the ring turns, brighter green flashes travel along the parallel step facets.

Twenty-three old-cut and single-cut diamonds follow the outline of the emerald, giving the cluster the crisp geometry of late Art Deco design. In profile, split shoulders rise to meet a pierced gallery with repeating triangular openings. The emerald is in excellent surface condition, with no abrasion observed on inspection.
