1 Carat Fancy Light Blue Green VS2 Cushion Cut Diamond Cluster Earrings
This matched pair of GIA-certified Cushion cut natural diamonds totals 1.00 carat, each stone graded Fancy Light Blue-Green VS2 (Rosenberg ref. 6930). Blue-green as a compound fancy color designation is among the rarest classifications issued by GIA — natural diamonds exhibiting simultaneous blue and green body color represent a structurally limited portion of annual fancy color submissions. VS2 clarity confirms inclusions remain invisible to the unaided eye and have no effect on light performance.
GIA Color Grade: Fancy Light Blue-Green
GIA grades fancy color diamonds on a saturation scale that, for blue and blue-green stones, runs Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, and Fancy Deep. Fancy Light indicates consistent, face-up body color that reads as distinctly chromatic rather than near-colorless, without reaching the higher saturation threshold of Fancy. The blue-green modifier reflects a dual-origin color mechanism — boron absorption accounts for the blue component while localized structural defects contribute the green — a combination that rarely produces calibrated matched pairs at any carat weight.
Why Cushion Cut for Fancy Color Stones
Cushion cut diamonds employ a modified brilliant facet arrangement within a rounded-corner outline, a configuration that retains body color more effectively than standard round brilliants by reducing the proportion of white light returned through the table. For fancy blue-green stones, the Cushion’s deeper pavilion and larger facets concentrate color saturation face-up, where GIA grading and visual assessment occur. The softened corners also reduce mechanical stress at the girdle — an important structural consideration in a cluster earring setting where stones sit in close proximity.
Cluster Setting in 18-Karat White and Rose Gold
The diamonds are set in a cluster construction combining 18-karat white gold and 18-karat rose gold — a two-tone framework that provides tonal contrast against the cool blue-green body color while maintaining the structural integrity required for daily wear. White gold prongs minimize optical interference with the diamonds’ color face-up, while the rose gold surround introduces warmth without competing with the stones. The post-and-backing system is engineered for secure retention consistent with the combined weight distribution of the cluster format.
