FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric symmetry, stylised motifs, clean lines, and a heavy reliance on platinum paired with diamonds.

Jewellery from this era predominantly utilised platinum for its strength and bright white finish, often accommodating old European or transitional cut diamonds.

Authentic pieces typically exhibit period-specific hallmarks, hand-cut stones with slightly asymmetrical facets, and intricate milgrain detailing characteristic of mid-20th-century craftsmanship.

Pairing historical jewellery with contemporary minimalist bands creates a striking contrast that highlights the intricate craftsmanship of the antique piece.

Clean the piece gently using warm water, mild washing-up liquid, and a soft-bristled brush, and store it separately in a lined jewellery box to prevent scratching.
