15 Carat G VS2 Round Brilliant Cut Diamond Stud Earrings
This matched pair comprises two GIA-certified Round Brilliant natural diamonds totaling 15.25 carats, graded G color and VS2 clarity, set in 18-karat white gold stud mountings (Rosenberg ref. 700331). Assembling a calibrated pair of Round Brilliants at this combined weight with consistent color and clarity grades is structurally uncommon — individual stones above 7 carats in the near-colorless range represent a small fraction of annual GIA submissions, and matching two such diamonds in cut and proportion compounds that scarcity significantly.
GIA Color and Clarity Grades: G and VS2
GIA grades white diamonds on a D-to-Z color scale; G falls in the near-colorless range, immediately below the colorless tier spanning D through F. At this position on the scale, any residual body color is imperceptible to the unaided eye, particularly in a white gold mounting that does not introduce warm reflected light into the pavilion. VS2 clarity places each stone in the very-slightly-included range: inclusions require magnification to detect and exert no influence on light transmission or optical performance at this carat weight.
Why Round Brilliant Cut for Stud Earrings at This Scale
The Round Brilliant is the most optically efficient diamond cut, with 57 or 58 facets engineered to maximize internal reflection and return white light directly to the viewer. At individual stone weights above 7 carats, the facet geometry generates a broad, high-contrast dispersion pattern that remains visible at conversational distance under ambient light — the dominant viewing condition for earrings. No other cut produces equivalent brightness-to-diameter performance in a symmetric stud format.
18-Karat White Gold Four-Prong Stud Setting
Each diamond is secured in a handmade 18-karat white gold four-prong basket, a configuration that minimizes metal coverage over the table while maintaining girdle security against lateral stress. The four-prong arrangement distributes clamping force evenly at the girdle plane, which is the appropriate geometry for a Round Brilliant at this diameter. Friction-post backs provide the clamping resistance required for long-term wear stability at this combined stone weight.
