Gorgeous Vintage‑Modern Jadeite and Diamond Cluster Ring
A beguiling vintage‑modern estate item centring a beautiful oval cabochon of green jadeite jade—measuring 15.71 mm by 9.56 mm with a depth of 5.05 mm—encircled by a halo of twenty‑two round brilliant‑cut natural diamonds, all set within an elegant, raised basket‑style mount. The ring is crafted with a fine 9‑carat white‑gold shank, providing a soft yet substantial setting that comfortably supports the delicate cluster while remaining wearable for everyday appreciation.
The jadeite and diamonds
The central stone is a medium semi‑opaque to opaque yellowish‑green jadeite jade, with subtle white mottling and a warm, organic character that glows softly under light. Under standard gemmological examination, no indications of treatment were observed, and the stone appears free of chips or visible flaws to the naked eye, lending it a clean, natural presence. The surrounding twenty‑two round brilliant‑cut diamonds average between 1.81 mm and 2.19 mm in diameter, with depths of approximately 1.22 mm, and together contribute an estimated total diamond weight of about 0.660 carats. Each diamond is individually secured in a neat, sparkling halo that gently frames the jadeite jade and enhances its polished richness.
An ingenious and beautiful alloy in the basket mount
The ring’s raised basket mount is a particularly interesting element: analysis reveals that the alloy forming this delicate structure contains approximately 23.83% gold (equivalent to around 5.75‑carat gold), 55.95% silver, and 18.29% palladium. This combination does more than simply strengthen the basket mount; the palladium plays a key role in both whitening and stabilising the metal. As a highly precious metal, palladium imparts a bright white tone to the metal to lift the tone of the gold–silver mix, giving the basket a bright finish that beautifully complements the fresh green of the jadeite. At the same time, its inherent hardness and durability help support the claw‑set diamonds and the cabochon stone, ensuring the cluster remains strong and secure, even as the setting lifts prominently above the shank.
Jadeite and Diamond Cluster Ring
The ring has a “vintage‑modern” feel: the cluster recalls the soft, organic motifs of early‑20th‑century design, yet the clean lines and precise setting speak to a more contemporary sensibility. The jadeite is secured by four fine claws, with the halo of tiny claw‑set diamonds held in a pierced, lightly raised basket‑mount that allows glimpses of the under‑gallery and adds a refined, airy lift to the composition. The shank itself is softly squared in profile, measuring approximately 1.45 mm at its slimmest and 2.90 mm at its widest, with a reassuring thickness that contributes to the ring’s overall sturdiness.
The ring is in very good condition, with the shank remaining of solid gauge and the mount secure. One diamond in the halo shows minute surface chipping only visible under loupe magnification, and even then, it is extremely difficult to spot, having no detrimental effect on the ring’s appearance or wearability. The 18‑carat hallmark present on the shank is understood to be inaccurate; specialist XRF analysis confirms the true composition as outlined above (please see valuation, pictured), reinforcing the ring’s interest as a piece of quietly innovative, rather than strictly conventional, jewellery.
Sized to British ring size O (resizable for a perfect fit)
