13 Carat Fancy Intense Yellow VS1 Radiant Cut Diamond Ring
The center stone is a 12.51-carat Fancy Intense Yellow VS1 Radiant cut natural diamond, GIA certified (Rosenberg ref. 700676). Twelve-carat-plus Radiant cuts in Fancy Intense Yellow represent a vanishingly small fraction of annual GIA submissions — at this weight and saturation grade, supply is structurally limited, and stones of comparable specification rarely enter the open market in any volume.
GIA Color Grade: Fancy Intense Yellow
GIA grades natural yellow diamonds on a scale from Faint through Fancy Vivid. Fancy Intense Yellow sits two grades above Fancy Yellow and one below Fancy Vivid, indicating deep, uniform face-up saturation achieved through body color alone — not fluorescence or favorable color zoning. VS1 clarity places the diamond firmly in the very-slightly-included range: no inclusions are detectable by the unaided eye, and light performance is unaffected at this carat weight.
Why Radiant Cut for Fancy Intense Color
The Radiant cut was developed specifically to maximize color retention in fancy color diamonds while maintaining the brilliance of a full modified-brilliant facet structure. Unlike emerald or Asscher step cuts, which allow saturation to concentrate unevenly, the Radiant’s facet arrangement distributes color across the entire face-up surface. At 12.51 carats, the extended table amplifies the Fancy Intense body color to a degree that no step-cut configuration at equivalent grade can replicate.
Three-Stone Platinum Setting with Trillion Side Stones
Two matched Trillion-cut side diamonds, 2.57 carats total weight, flank the center stone in a triangular silhouette that echoes the angular geometry of the Radiant outline. Trillions direct visual attention inward without generating competing brilliance, while their broad spread maintains proportional balance against a 12-carat center. The mount is handmade platinum — the standard metal for investment-grade fancy color settings due to its 95% purity, structural density, and resistance to prong wear across decades of use.
