A striking late Edwardian / early Art Deco diamond ring crafted in platinum and set with a rich composition of antique cut diamonds arranged in a softly domed bombé design.
The central old European cut diamond weighs approximately 0.68 ct (I color, SI2 clarity) and is surrounded by additional old cut diamonds — including old European, old mine and rose cuts — with an estimated combined weight of approximately 1.62 ct.
Beautiful early 20th-century craftsmanship is visible in the delicate hand-made openwork and fine millegrain detailing. The elegant domed form gives the ring a bold yet refined presence.
