This Art Deco engagement ring belongs to the 1930 period and takes the form of a solitaire ring. The piece is fashioned from 18ct yellow gold and platinum, displaying a colour combination of warm yellow gold alongside white precious metal. A round old-cut diamond weighing approximately 0.42ct sits in a secure solitaire setting at the centre, flanked by detailed fan-etched and engraved shoulders. The platinum-set diamond measures 5mm by 5mm by 3mm and stands 5.8mm off the finger. Hallmarks reading 18CT and PLAT appear on the metal, while light wear is visible in keeping with age. In a modern home, this jewellery piece serves as a traditional proposal ring or joins a private collection for daily wear. The design brings period character to the wearer, suiting formal occasions as well as everyday attire. It slips easily onto a UK size L or US size 5.75 finger, pairing well with other vintage or contemporary bands. Collectors of fine period jewellery will find this item a fitting addition to an existing assortment of precious rings.

FAQs

Art Deco jewellery, prominent from 1920 to 1935, is characterised by geometric shapes, clean symmetrical lines, contrasting metal colours, and detailed metalwork such as filigree and engraving.

Art Deco rings frequently combined 18ct yellow or white gold with platinum settings, which allowed for intricate, durable claw work and lightweight millegrain detailing around diamonds and gemstones.

Authentic Art Deco pieces often feature period hallmarks, hand-engraved shoulders, platinum-topped mountings on gold bands, and old European or transitional cut diamonds.

Art Deco engagement rings pair well with plain metal wedding bands or slender pave bands, allowing the geometric shoulder details and central solitaire diamond to remain the focal point.

Clean gently using warm water, mild soap, and a soft-bristled brush, avoiding harsh chemicals, and have the claws periodically inspected by a jeweller to ensure stone security.
