What is Art Deco jewellery?

Definition
Art Deco jewellery emerged in the 1920s and 1930s, taking its name from the 1925 Paris exhibition L'Exposition Internationale des Arts Décoratifs. The style is defined by bold geometric shapes, symmetry, strong contrasts between black and white or bright colour, and a preference for platinum and white gold set with diamonds, sapphires, emeralds and onyx. Designs drew on Egyptian, ancient Greek, Aztec and Cubist influences, giving pieces a sleek, modern look that still feels sophisticated today.
Frequently asked questions
- What years does Art Deco jewellery cover?
- Most experts place the Art Deco period in jewellery between roughly 1920 and 1935, with 1925 often cited as its defining moment. Some pieces show the influence extending into the early 1940s, and there is overlap with Art Moderne from around 1935.
- What metals and stones are typical in Art Deco jewellery?
- Platinum and white gold were strongly favoured because their cool tone suited the white diamond and geometric style. Calibré-cut coloured stones, especially sapphires, emeralds and rubies alongside onyx and coral, were used for strong colour contrast.
- How can I tell if a piece is genuinely Art Deco?
- Look for geometric patterns, sharp angles, milgrain edging, filigree work and symmetric designs, often with contrasting black and white or bright colour. A hallmark and manufacturing marks can help date a piece, and a specialist appraiser can confirm authenticity.
