This custom Art Deco–inspired ring by Carl Blackburn highlights the striking contrast of two step-cut stones set side by side: a vivid emerald-cut green emerald paired with a crisp Asscher-cut diamond.
Framed in a clean yellow gold bezel, the composition feels bold, balanced, and unmistakably architectural, with the emerald’s rich color standing out against the diamond’s refined hall-of-mirrors brilliance.
The close-set arrangement creates a unified, graphic look that recalls the strong geometric glamour of the 1920s.
