15 Carat E VS2 Asscher Cut Diamond Ring
The center stone is a 15.00-carat E VS2 Asscher cut natural diamond, GIA certified (Rosenberg ref. 96685). At fifteen carats, Asscher cut diamonds in the colorless range are among the rarest configurations encountered in trade — GIA submissions of Asscher cuts above ten carats in the D–F colorless bracket represent a fraction of annual grading volume, and stones exceeding fifteen carats at this color and clarity grade are structurally limited in supply regardless of market conditions.
GIA Color Grade: E Colorless
GIA grades white diamonds on a color scale from D through Z, with D, E, and F constituting the colorless category. E color indicates the near-absence of detectable body color — distinguishable from D only by a trained grader under controlled conditions, and indistinguishable from D to the unaided eye in any lighting environment. VS2 clarity places the stone in the very-slightly-included range: any inclusions present are not visible without magnification and carry no consequence for light performance or transparency at this carat weight.
Why Asscher Cut for a Colorless Stone of This Weight
The Asscher cut is a square step cut with cropped corners, producing a concentric, hall-of-mirrors optical effect through its large, open table and parallel facet rows. Unlike brilliant cuts, the step facet structure transmits light without scattering it — a characteristic that places direct emphasis on color and clarity rather than obscuring them. This makes the Asscher the preferred configuration for D–F colorless diamonds, where the absence of body color is itself the primary value factor. At fifteen carats, the broad table surface amplifies this transparency to a degree unreachable at lower weights.
Three-Stone Platinum Setting with Step-Cut Side Stones
The center stone is set in a handmade platinum three-stone mounting flanked by step-cut side diamonds, a configuration chosen to reinforce the architectural geometry of the Asscher rather than introduce competing brilliance. Platinum — at 95% purity and with density superior to white gold — is the standard metal for settings holding stones of this value, providing long-term prong integrity against wear. Custom prong placement around the Asscher’s cropped octagonal corners is required to protect the girdle edge, a precision that handmade construction allows in ways that cast settings cannot.
