This solitaire engagement ring features a 1.59 carat old mine cushion cut diamond in 14 karat yellow gold. The fancy brown diamond has I1 clarity, giving it a warm cognac tone with visible inclusions that add natural character. Set in a split-claw basket with four prongs, the square cushion cut maximizes the diamond's surface area and vintage-inspired faceting. The ridged band measures 2.4 mm wide and pairs well with the antique center stone.
