FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric symmetry, clean lines, stylised motifs, and a strong influence from modern industrial design and cubism.

Jewellers of this era predominantly utilised platinum and white gold as a setting to enhance the brilliance of diamonds, frequently pairing them with high-clarity coloured gemstones like sapphires, rubies, and emeralds.

Authentic pieces typically feature period-specific gemstone cuts such as emerald, baguette, or old European cuts, alongside hand-engraved details, milgrain edges, and period hallmarks stamped inside the band.

An antique ring acts as a focal point and can be worn as a standalone statement piece or paired with minimalist contemporary bands to create a deliberate contrast between eras.

Store pieces individually in lined boxes to prevent scratching, avoid exposing delicate gemstones to harsh ultrasonic cleaners or chemicals, and have the prongs checked periodically by a professional jeweller.
