The cut-cornered rectangular modified brilliant — more commonly known as the radiant cut — was invented in 1977 and remains one of the most technically demanding diamond cuts to execute well. Its 70 facets combine the emerald cut’s elegant rectangular silhouette with the round brilliant’s explosive light performance, producing a stone that is simultaneously architectural and fiery. This exceptional 5.16-carat natural diamond, GIA certified K color and SI1 clarity, delivers exactly that: a stone of commanding presence and dynamic brilliance. K color in a large diamond of this cut reads as warm and luminous rather than yellow — a characteristic many collectors actively seek for its rich, champagne-adjacent glow. Set in 8.2 grams of 18k yellow gold that complements the stone’s warmth beautifully. Brand new, size 6.5 — a rare opportunity at this carat weight.
