GIA-certified Type A jadeite and omphacite jade oval double cabochon and approximately 3.00 carat old cut round brilliant diamond F-G/VS 18K white gold cocktail ring, featuring the vivid green untreated jade in a prong setting surrounded by a grand double-row starburst cluster halo of old cut diamonds radiating outward in a classic sunburst formation. Size 7, adjustable.

The setting is a classically proportioned double-row starburst cluster in 18K white gold, with round brilliant old cut diamonds of varying sizes arranged in two concentric radiating rows around the jade cabochon — larger diamonds anchoring the outer border and smaller stones filling the inner row, creating a full sunburst effect that dramatically frames the deep green jade center. The individual prong mounts for each diamond are raised, giving the cluster dimensional depth and allowing each stone to be viewed in full from above, while the high-polish white gold shank provides a clean, substantial base for the imposing head. The overall silhouette is reminiscent of the finest mid-century estate jewelry, where cluster diamond surrounds were the premier setting style for important colored gemstones.

The GIA-certified Type A jadeite and omphacite jade is among the most significant designations in the colored stone world — Type A jade is entirely natural and untreated, with no dye, no bleaching, and no polymer impregnation, meaning the vivid green color and translucency are entirely the result of nature. The GIA report confirms "no indications of dye or impregnation," placing this stone in the highest tier of jade quality and authenticity. Known in the Chinese trade as "Fei Cui" — a term evoking the plumage of the kingfisher bird — this variety of jade is the most prized in Chinese culture and commands extraordinary premiums over treated jade. Measuring 17.52 x 13.26mm with translucent clarity and deep green color, this cabochon displays the characteristic waxy luster and inner light that defines fine jadeite at its best. For collectors of Asian luxury objects or fine gemstone jewelry, a GIA-certified Type A Fei Cui jade of this size and color is an exceptional and increasingly rare acquisition.
