FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric precision, symmetry, streamlined silhouettes, and a strong influence from modernist art and architecture.

Jewellers of this era frequently utilised platinum-topped gold settings to enhance the brilliance of diamonds, alongside yellow gold or white gold bands featuring hand-cut millegrain edges and delicate filigree work.

Authentic pieces typically feature hand-cut diamonds such as old European cuts or old mine cuts, which exhibit smaller tables and higher culets, combined with period hallmarks and hand-fabricated metalwork rather than modern casting.

An antique ring pairs effectively with contemporary minimalist bands to create a mixed-era stacked look, allowing the intricate historical details to contrast against clean, modern lines.

Antique jewellery should be cleaned gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners that can loosen aged settings, and stored separately in a lined box to prevent scratching.
