About The Setting
The 18K white gold mounting is a study in controlled contrast and design intelligence — the aquamarine sits within a clean white gold bezel surrounded by a crisp ring of 34 round brilliant diamonds that separate the seafoam center stone from the vivid green tsavorite dome beyond, creating a three-zone color composition of seafoam / white / chrome green that reads as both harmonious and visually dynamic. The tsavorite pave is set in deliberately oxidized or blackened white gold prongs that recede optically against the intense green of the garnets, maximizing color saturation and making the dome appear as a continuous field of pure vivid green rather than a paved surface with visible metal. The reverse reveals an open diamond lattice gallery that demonstrates the structural sophistication of the mounting — a crosshatch framework that supports the dome without adding unnecessary weight, allowing light to enter the aquamarine from below and enhancing its characteristic color and translucency. At 9.65 grams the ring has excellent weight despite the open gallery construction.
About The Stones
The 20.86 carat oval aquamarine cabochon is an extraordinary specimen — at this carat weight in a cabochon cut, the stone displays its characteristic sea-glass color as a smooth, uninterrupted color field rather than through faceting, producing a calm, glowing center of pale seafoam blue-green that provides a serene counterpoint to the intense chrome green of the surrounding tsavorite pave. Aquamarine cabochons of this size are significantly rarer than faceted equivalents, as the cabochon cut requires a stone with exceptional color evenness and transparency that can stand up to close examination without facets to mask internal characteristics. The 118 tsavorite garnets totaling 3.45 carats are among the most vivid and saturated green gemstones available in the gem market — chrome vanadium-colored tsavorites from Kenya and Tanzania consistently produce a brighter, more intensely chromatic green than any other garnet variety and many emeralds of equivalent quality, making this dome one of the most chromatically powerful green pave surfaces possible in fine jewelry.
