This antique engagement ring from the 1920s exhibits an Art Deco trilogy design made from 18ct yellow gold and platinum. The front holds a central rectangular stone flanked by two smaller square-shaped stones, all secured inside clean metal bezel settings on a tapered shank. The metalwork combines warm yellow tones on the band with bright white platinum settings around the stones. Visible details include crisp geometric lines, flush metal borders, and smooth polished surfaces reflecting light across the stone facets. The face of the ring spreads 1 cm across and measures 4 mm wide. Today, this piece serves primarily as a traditional engagement ring or a meaningful addition to a fine jewellery collection. It sits comfortably on the hand and pairs well with both vintage and modern bands. The low-profile geometric mount ensures practical everyday wear without catching on clothing. Collectors of early 20th-century jewellery will appreciate the classic proportions and the combination of two-tone precious metals.

FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric symmetry, clean lines, and architectural box settings. It frequently combines yellow gold shanks with white metal or platinum tops to highlight diamonds.

Art Deco three-stone rings were predominantly crafted using 18ct yellow gold for the band, paired with platinum or white gold rub-over settings to secure old cut or step-cut diamonds.

Authentic pieces feature period metal hallmarks, geometric or collet settings, milgrain edging, and hand-cut diamonds such as old European or step cuts rather than modern brilliant cuts.

Art Deco rings pair well with minimalist modern bands or complementary mixed-metal jewellery, allowing the geometric setting of the vintage piece to serve as the focal point.

Clean gently using warm water, mild soap, and a soft-bristled brush. Avoid harsh chemical cleaners and have the stone settings inspected regularly by a professional jeweller to ensure security.
