This exceptional antique ring dates stylistically to the early Art Deco period, an era celebrated for its emphasis on symmetry, geometry, and refined craftsmanship. The design reflects the architectural clarity typical of early Art Deco, beautifully combined with traditional hand-finishing and exquisite materials.

At its center sits a natural ruby in a cushion cut, unheated, weighing approximately 0.40 carats.

The ruby displays a vivid, rich red hue and is framed by ten Old Cut diamonds, with a total diamond weight of approximately 0.40 carats. The diamonds are set in platinum, enhancing their brilliance and providing a striking contrast to the warm gold tones.

The ring shank is crafted in 18k yellow gold, while the ring head is executed in platinum — a highly characteristic and desirable material combination of the Art Deco era. The finely pierced gallery at the reverse further underscores its period authenticity and quality of manufacture.

A timeless and elegant antique ring, equally suited for collectors and for those seeking a unique engagement or statement piece with history and character
