FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric symmetry, clean lines, and a heavy reliance on platinum settings paired with contrasting yellow gold.

Traditional pieces typically feature a combination of 18ct yellow gold shanks with platinum settings, which allowed for secure, delicate claw and millegrain work to showcase old-cut diamonds.

Authenticity is identified through hallmark stamps, hand-cut diamond facets such as old European cuts, and period-specific manufacturing techniques like hand-beaded millegrain edging.

Antique rings add historic character to contemporary wardrobes and pair effectively when stacked alongside minimalist modern bands or worn as a standalone statement piece.

Preservation requires regular professional checks of the prong settings, gentle cleaning with warm soapy water and a soft brush, and separate storage to prevent scratching.
