FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric precision, symmetrical designs, and a strong influence from modernist architecture and industrial forms.

Platinum became the metal of choice during the Art Deco era due to its strength, which allowed for delicate settings, alongside white gold and accent stones like diamonds, sapphires, and emeralds.

Authentic pieces often feature period-specific diamond cuts such as old European or single cuts, hand-carved millgrain details, and hallmarks indicative of early 20th-century metal smithing.

An antique ring pairs effectively with contemporary minimalist garments or mixed-metal modern accessories, allowing the historical craftsmanship to serve as a distinct focal point.

Platinum and diamonds should be cleaned periodically using warm soapy water and a soft brush, and inspected annually by a professional jeweller to ensure the security of the stone settings.
