FAQs

The Art Deco period, spanning from the 1920s to the 1930s, is characterised by geometric symmetry, streamlined shapes, and a heavy influence from industrial design and modernist art.

Jewellery from this era frequently utilised platinum, white gold, and diamonds featuring old European or transitional cuts, often accented with calibre-cut gemstones.

Authentic pieces typically feature period-appropriate gemstone cuts such as old mine or old European cuts, hand-carved milgrain detailing, and correct metallurgical hallmarks for the 1930s.

An antique ring pairs well with contemporary minimalist clothing to let the intricate historical craftsmanship stand out as a focal point.

Regular professional inspections of the setting and gentle cleaning with warm soapy water and a soft brush help maintain the integrity of the precious metals and stones.
