FAQs

Art Deco jewellery, prominent from the 1920s to the 1940s, is characterised by geometric precision, symmetrical designs, stylised motifs, and a strong architectural influence, often utilising platinum and white gold to highlight diamonds.

Jewellery from this era frequently featured platinum as a strong, durable setting material alongside white or yellow gold, paired with hand-cut diamonds such as old European cuts and old mine cuts.

Authentic pieces typically exhibit period-correct hand-cut stones, detailed milgrain edging, openwork filigree metalwork, and appropriate metal hallmarks or makers marks consistent with the era.

An antique ring provides a distinctive contrast when paired with minimalist modern attire, allowing the historic craftsmanship and unique diamond facets to stand out as a focal point.

Preserve the integrity of antique rings by cleaning them gently with warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners, and having the prongs inspected periodically by a professional jeweller.
