15 Carat D Flawless Pear Shape Diamond Ring
The center stone is a 15.02-carat D Flawless Pear Shape natural diamond, GIA certified, classified as Type IIa (Rosenberg ref. 96050). Type IIa diamonds contain no measurable nitrogen or boron in their crystal lattice, a structural condition found in fewer than two percent of all gem-quality diamonds submitted to GIA annually. At 15 carats with a D Flawless grade, this stone represents a category where supply is structurally limited regardless of market conditions — the intersection of maximum color, maximum clarity, and this weight class is rarely encountered in a single stone.
GIA Color and Clarity: D and Flawless
On GIA’s color scale, D is the absolute starting point — a grade assigned only when no color can be detected under controlled conditions using a comparison set of master stones. Flawless denotes the absence of any internal inclusions or external blemishes at 10× magnification, the highest clarity grade GIA issues. The combination of D color and Flawless clarity, reinforced by the Type IIa designation, places this diamond at the extreme upper boundary of grading criteria across all three systems simultaneously.
Why Pear Shape for a Stone at This Scale
The Pear Shape combines a brilliant-cut facet pattern with an elongated, tapered outline — a configuration that maximizes light return while visually extending the apparent length of the stone across the finger. At 15 carats, the elongated geometry distributes the carat weight efficiently face-up, producing a larger apparent surface area than a round brilliant of equivalent weight. The pointed terminus also draws the eye along the full length of the stone, accentuating its scale without requiring an oversized setting profile.
Platinum Micropavé Setting and Construction
The diamond is set in handmade platinum, the preferred metal for stones at this grade level due to its density, 95% purity, and negligible long-term prong wear. The micropavé construction along the shank sets small accent diamonds in minimal shared-prong mounts machined to precise depth, allowing the band to recede visually and direct attention entirely to the center stone. Platinum’s naturally white reflectivity maintains D color neutrality at the girdle, ensuring the metal does not introduce any warm tint at the stone’s perimeter.
