17 Carat D VS1 Cushion Cut Diamond Ring
The center stone is a 16.78-carat D VS1 Cushion cut natural diamond, GIA certified (Rosenberg ref. 96471). Cushion cut diamonds at this carat weight with D color and VS1 clarity represent a category rarely encountered in the primary or secondary market — stones above 15 carats in colorless grades account for a structurally marginal share of annual GIA submissions, and the combination of top color with near-flawless clarity at this scale narrows availability further.
GIA Color and Clarity: D and VS1
D is the highest color grade on GIA’s D-to-Z scale, indicating the complete absence of body color when the stone is viewed face-down against a white background under standardized lighting. It is the benchmark against which all other colorless grades are measured. VS1 clarity places the diamond in the very-slightly-included range — inclusions are not visible to the unaided eye and have no effect on light performance or structural integrity. At 16.78 carats, VS1 transparency allows the stone’s full optical depth to transmit without internal interference.
Why Cushion Cut at This Weight and Color Grade
The Cushion cut applies a modified brilliant facet pattern within a softened rectangular or square outline, producing broad, open flashes that are particularly effective at demonstrating colorless light return in D-grade stones. Unlike round brilliants, the Cushion’s larger table facet reveals the interior of the stone directly — at this carat weight, that depth of display is architecturally significant. The cut’s rounded corners also reduce vulnerability to edge chipping, a meaningful consideration in a stone of this scale intended for daily wear.
Handmade Platinum Three-Stone Setting with Heart Shape Side Stones
Two Heart Shape diamonds, matched at 2.60 carats total weight, D VS1, flank the center stone in a handmade platinum mount. Heart Shapes in a three-stone context provide a curved, directional silhouette that complements the Cushion’s soft outline without introducing competing facet patterns. Platinum is the standard metal for settings of this caliber — its 95% purity, density, and prong durability ensure structural security over decades of wear without the periodic re-plating required by white gold.
