FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric symmetry, clean lines, stylised motifs, and a strong influence from industrial design and modernist art.

Plutinum became the dominant metal of choice during the Art Deco era due to its strength, allowing for delicate millegrain edges and secure settings, frequently paired with diamonds and calibrated gemstones.

Authentic pieces often exhibit period-specific stone cuts such as old European or old mine cuts, hand-crafted millegrain detailing, natural age-related patina on the metal, and traditional makers marks or hallmarks characteristic of the era.

An antique ring pairs effectively with contemporary minimalist bands to create a contrast in eras, or layered alongside geometric stacking rings that echo the architectural design of the period.

Regular professional inspections are recommended to check the integrity of the claw settings and millegrain work, while cleaning can be performed gently using warm soapy water and a soft brush to remove everyday oils.
