This Art Deco engagement ring from circa 1935 holds a 1.00 carat old mine cut diamond with an E colour grade and SI2 clarity. The diamond is secured by four split claws within an angular geometric gallery and sits upon a slim, tapering 18k white gold shank with French hallmarks. The visible details include the polished silver-toned metal band, the multifaceted clear gemstone, and the pierced shoulders with delicate cut-out openings. The item measures 30 cm high, 25 cm wide, and 5 cm deep in practical terms on the display surface. Suitable for personal wear as a traditional engagement ring, this piece brings a vintage aesthetic to daily attire or special occasions. The platinum setting contrasts with the white gold band, presenting a cohesive silver-toned palette. The classic solitaire configuration allows it to pair easily with wedding bands or other jewellery items worn on the hand.

FAQs

Art Deco rings from the 1920s and 1930s typically feature clean geometric silhouettes, streamlined bands, and refined metalwork, often highlighting central gemstones such as old cut diamonds within platinum or white gold mountings.

Rings from this era predominantly utilised platinum or white gold for settings to complement white diamonds, featuring hand-cut diamonds such as old European or cushion cuts held by claw or bezel settings.

Authentic period pieces generally exhibit historic hallmarks, characteristic hand-cut diamond facets with small tables and open culets, and hand-finished shoulder detailing rather than modern cast precision.

An Art Deco ring functions as a focal piece that layers comfortably alongside plain contemporary metal bands or can be worn individually as an understated statement of historic craftsmanship.

Clean fine jewellery gently using warm water with mild soap and a soft-bristled brush, avoiding harsh chemicals, and arrange annual inspections with a professional jeweller to ensure claw settings remain secure.
