This exquisite iconic 1940s tank ring exemplifies Art Deco elegance with its striking 18K gold construction. Luminous mine-cut diamonds, totaling approximately 1 carat, form an impressive arch across the center, flanked by vibrant ruby accents. Distinctive bell-shaped elements frame the top and bottom, while the concave face and graduated shoulders create dimensional sophistication. Open-back settings allow light to dance through each gemstone, enhancing their brilliance. A timeless statement piece that captures the glamour and architectural precision of vintage Hollywood Regency design.
