Antique Art Deco 1920s, Certified 3.10 Carat Diamond Onyx Platinum Dinner Ring

About the Item

In the early 20th century, Black advanced from being a colour reserved for mourning jewellery to being an elegantly fashionable one, valued for providing striking contrasts. In Art Déco jewellery especially, black materials emphasized the clean, graphic lines that mark the era's best pieces. This ring, dating to the late 1920s, could barely be a more perfect picture book example of an Art Déco dinner ring. Relying on chic geometries and a sleek black-and-white contrast, the ring juxtaposes sparkling diamonds with glossy black onyx. An old European cut diamond of 2.40 ct is the focal point of the design. Its fine colour (Top Wesselton) is emphasized by the black onyx surround, while a subtle platinum millegrain setting lets the gemstone appear even larger. A total of sixteen further diamonds within stepped settings typical of the era surround the polished onyx on four sides. Elegantly engraved ring shoulders lead over to the delicate shank, which completes the design. A wonderful example of Art Déco design and craftsmanship in excellent condition. We found the ring in Munich.
