This Art Deco diamond ring reflects early 20th-century taste for diamond-set platinum detail. The yellow-gold band gives warmth, while the platinum setting brightens the diamond cluster.
The design feels softer than strict geometric Art Deco. However, the platinum and diamond combination still fits the period’s love of bright white metal. GIA notes that Art Deco jewelers used platinum, white gold, geometric shapes, and strong contrast.
Design Description
This ring is crafted in 18ct yellow gold and platinum. It features one diamond weighing 0.07ct, plus 10 diamonds totalling 0.28ct. The full diamond weight is 0.35ct.
The ring weighs 2.2g and measures 8.3mm wide. Ojamie lists the height as 3.5mm and the size as L. The scale makes it delicate, wearable, and suitable for antique diamond collectors.

GIA’s Art Deco jewellery guide explains that Art Deco jewellers used platinum, white gold, geometric shapes, and strong contrast. This supports the ring’s platinum diamond setting and early 20th-century design character.
The V&A’s Art Deco fashion guide notes that icy combinations of diamonds, rock crystal, and platinum came forward in the 1920s and 1930s. This gives useful context for the ring’s platinum and diamond face.
GIA’s 4Cs guide explains that diamond quality depends on colour, clarity, cut, and carat weight. This helps frame the 11 diamonds as the main value and beauty feature of the ring.
