30 Carat D VS2 Cushion Cut Diamond Ring
The center stone is a 30-carat D VS2 Cushion cut natural diamond, GIA certified (Rosenberg ref. 96698). Thirty-carat D-color diamonds of this clarity represent one of the most structurally scarce categories in the natural diamond market — stones at this specification are encountered almost exclusively through dedicated auction events or private treaty transactions, and rarely surface more than once per generation within a given market.
GIA Color Grade: D and VS2 Clarity
GIA grades white diamonds on a color scale from D through Z, where D denotes the complete absence of detectable body color under controlled laboratory conditions — the highest grade the scale accommodates. VS2 clarity places the diamond in the very-slightly-included range: inclusions are not visible to the unaided eye and have no effect on light transmission or brilliance. At thirty carats, VS2 is a clinically meaningful clarity threshold, as the stone’s expanded table surface makes any face-up transparency the primary performance variable.
Why Cushion Cut for a Stone at This Scale
The Cushion cut combines a softened rectangular or square outline with a modified brilliant facet pattern — a structure that generates strong light return across both daylight and incandescent environments while preserving the broad face-up surface area characteristic of larger stones. For a D-color diamond of this weight, the Cushion’s deeper pavilion and larger facet planes amplify transparency rather than masking it, allowing the stone’s absence of body color to express fully through light performance.
Three-Stone Platinum Setting
The center diamond is set in a handmade platinum three-stone mounting, with two side stones calibrated to the proportions of the center stone and positioned to frame rather than compete with it. Platinum is the standard metal for settings carrying stones of this significance — its 95% purity, resistance to prong wear, and structural density ensure long-term integrity without requiring the rhodium plating that white gold demands over time.
