FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric shapes, clean lines, stylised motifs, and the frequent use of platinum paired with diamonds and calibrated gemstones.

Jewellery from this era predominantly utilised platinum, which allowed for delicate yet strong settings, alongside white gold and yellow gold, often set with old European cut or old mine cut diamonds.

Authentic pieces typically feature period-appropriate hand-cut diamonds such as old European cuts, hand-carved or pierced platinum settings, and makers marks or hallmarks consistent with early 20th-century metallurgy.

An antique ring can be worn as a standalone statement piece or paired with contemporary minimalist bands to create a deliberate contrast between historical craftsmanship and modern aesthetics.

Preserve antique jewellery by having the claw settings professionally inspected annually, storing pieces individually in soft pouches, and cleaning them gently with warm soapy water and a soft brush.
