20 Carat D Flawless Emerald Cut Diamond Earrings
The matched pair totals 19.78 carats — two Emerald cut natural diamonds grading D color and Flawless clarity, GIA certified (Rosenberg ref. P-12110). Assembling two stones of this weight and grade in a calibrated pair is among the most exacting sourcing exercises in the white diamond market; D Flawless Emerald cuts above nine carats are rarely encountered individually, and matched pairs at this scale represent a structurally constrained category of supply regardless of market conditions.
GIA Grades: D Color and Flawless Clarity
D is the highest designation on the GIA D-to-Z color scale, indicating complete absence of body color when the stone is evaluated face-down against a white reference. Flawless is the apex of the GIA clarity scale, denoting no internal or external characteristics visible under 10× magnification by a trained grader. The D/FL combination places these diamonds at the theoretical ceiling of white diamond grading — a classification achieved by fewer than a fraction of one percent of stones submitted annually to GIA.
Why Emerald Cut for D Flawless Material
The Emerald cut is a step-cut format defined by parallel rectangular facets and an expansive open table, a structure that emphasizes transparency and color fidelity over scintillation. For D Flawless stones, this architecture functions as a precision instrument — the broad step facets amplify the absence of body color and the optical purity of the crystal rather than distributing light across a fine-detail facet pattern. Any inclusion or color presence is immediately apparent in an Emerald cut, which is precisely why Flawless, D-color material is the natural pairing for this shape.
Platinum Setting and Mounting Construction
Each stone is set in handmade platinum, chosen for its 95% purity, structural density, and neutral white tone that introduces no warmth into D-color diamonds. The mounts are fitted with omega-back closures — the preferred mechanism for stones of this weight, providing the secure grip and even distribution of load required to wear earrings approaching ten carats per ear. Prongs are individually fitted to each stone’s dimensions to preserve the unobstructed pavilion geometry characteristic of the Emerald cut.
