20 Carat Fancy Intense Yellow VVS1 Radiant Cut Diamond Ring
The center stone is a 20.51-carat Fancy Intense Yellow VVS1 Radiant cut natural diamond, GIA certified (Rosenberg ref. 700764), set in 18kt yellow gold. Twenty-carat-plus fancy color diamonds represent an exceptionally rare tier of GIA submissions — at this weight, Fancy Intense Yellow Radiant cuts are rarely encountered in the secondary or primary market, placing this stone in a category where supply is structurally limited by natural occurrence alone.
GIA Color Grade: Fancy Intense Yellow
GIA grades natural yellow diamonds along a saturation scale from Faint through Fancy Vivid. Fancy Intense Yellow indicates a high level of yellow saturation — stronger than Fancy Yellow and distinguished from Fancy Vivid by a precise colorimetric threshold that GIA evaluates face-up under controlled illumination. VVS1 clarity places the diamond at the uppermost tier of the very-slightly-included range: any inclusions present are extremely difficult to locate even under 10× magnification and have no measurable effect on light performance at this scale.
Why Radiant Cut for Fancy Intense Yellow
The Radiant cut combines a rectangular silhouette with a modified brilliant facet arrangement, a structure engineered to maximize both color saturation and light return simultaneously. For a 20-carat Fancy Intense Yellow, this facet pattern intensifies perceived body color face-up — the primary value driver in fancy color grading — while delivering a level of brilliance that step cuts cannot match. The cut geometry also distributes weight across a broad table, supporting the visual presence appropriate to a stone at this carat weight.
Three-Stone 18kt Yellow Gold Setting with Trapezoid Side Stones
Two matched Trapezoid-cut side diamonds, 2.01 carats total weight, grade D VVS2, flank the center stone in a step-cut format. Trapezoids provide a rectilinear frame that reinforces the Radiant’s outline without generating competing brilliance. The mount is handmade in 18kt yellow gold — the traditional choice for Fancy Intense Yellow stones, as the warm metal tone complements and sustains the diamond’s body color rather than neutralizing it as white metals can.
