15 Carat D VVS1 Marquise Shape Diamond Ring
The center stone is a 15.01-carat D color VVS1 Marquise cut natural diamond, GIA certified (Rosenberg ref. 700750). Marquise cut diamonds exceeding fifteen carats in D color with VVS1 clarity represent a convergence of scale, transparency, and grade rarely encountered outside major auction contexts — at this specification, stones do not enter the market on a predictable cycle, and supply is structurally constrained by the scarcity of rough capable of yielding both the carat weight and the color grade simultaneously.
GIA Color and Clarity: D Color, VVS1
GIA grades colorless diamonds on a scale from D through Z, where D denotes the complete absence of body color when evaluated face-down against a pure white reference under controlled lighting. VVS1 — Very Very Slightly Included, first degree — is one grade below Internally Flawless: inclusions are not detectable under 10× magnification except by a trained grader under ideal conditions. At 15 carats, VVS1 clarity ensures that no internal feature disrupts the stone’s optical performance or long-term structural integrity.
Why Marquise Cut at This Scale
The Marquise is an elongated brilliant-cut outline derived from the French navette form, with pointed terminations at both ends. Its length-to-width ratio maximizes perceived size per carat more efficiently than round or cushion formats, an effect that becomes pronounced at weights above ten carats. The full-brilliant facet pattern preserves the fire and scintillation characteristic of colorless diamonds while the pointed silhouette delivers a precise, architectural presence that distinguishes the cut from softer outlines.
Three-Stone Platinum Setting with Heart Shape Side Diamonds
Two Heart Shape diamonds totaling 3.08 carats, graded D Flawless — the highest combined color and clarity classification GIA issues — flank the center Marquise. Heart Shapes are an uncommon side-stone pairing; their pointed lower culet echoes the Marquise’s terminal geometry without generating competing visual weight. The mount is handmade platinum, chosen for its 95% purity, inherent whiteness that will not impart body color to a D-grade stone, and the structural density required to secure prongs around stones of this combined weight over decades of wear.
