5 Carat D Flawless Round Brilliant Cut Diamond Stud Earrings
The center stones are a matched pair of Round Brilliant natural diamonds totaling 5.46 carats, each graded D color and Flawless clarity, GIA certified (Rosenberg ref. 700627). Matched pairs at this combined weight, both graded to the absolute top of GIA’s color and clarity scales, are rarely encountered — the statistical probability of two stones achieving D Flawless simultaneously, at near-equal weights above 2.70 carats each, makes this combination structurally uncommon in any market cycle.
GIA Grades: D Color and Flawless Clarity
D is the highest designation on GIA’s D-to-Z color scale, indicating a complete absence of detectable body color when the stone is evaluated face-down against a standardized white background by a trained gemologist. Flawless is the most stringent clarity grade GIA assigns — it certifies that no inclusions or surface blemishes are visible under 10× magnification. At this grade combination, neither color nor clarity introduces any optical interference into the stone’s light performance.
Round Brilliant Cut: Optical Engineering for Colorless Diamonds
The Round Brilliant cut, with its 57 or 58 precisely calculated facets, is designed to maximize light return, brilliance, and scintillation through proportional and angular optimization. For D Flawless diamonds, the Round Brilliant is the preferred cut because its facet structure fully transmits the stone’s colorlessness — the complete absence of body color is rendered visible through face-up brilliance rather than obscured by it. No other shape achieves the same measurable balance of brightness and fire in a colorless stone.
18-Karat White Gold Four-Prong Stud Setting
Each stone is set in a handmade 18-karat white gold four-prong basket mount, a construction that minimizes metal coverage over the crown and table to preserve maximum light entry and face-up transparency. The posts are fitted with secure friction backs appropriate for stones of this weight and value. White gold at 18-karat purity — 75% fine gold — provides the structural rigidity required for long-term prong integrity while maintaining a neutral tone that does not introduce warmth adjacent to D-color stones.
