FAQs

Art Deco jewellery, prominent from the 1910s to the 1930s, is characterised by geometric precision, stylised motifs, and a transition away from the flowing curves of the preceding Edwardian and Art Nouveau periods.

Jewellery from this era frequently utilised platinum, yellow gold, and white gold, often set with old European cut diamonds, sapphires, rubies, and emeralds crafted using precise channel, bezel, or prong settings.

Authentic pieces often feature hand-cut stones with distinct culets, aged metal patinas, makers marks or hallmarks appropriate to the period, and construction techniques consistent with early twentieth-century bench manufacturing.

An antique ring pairs effectively with both minimalist modern attire and eclectic vintage ensembles, serving as a focal point that contrasts sharp contemporary lines with historical craftsmanship.

Preservation involves storing pieces in individual lined compartments, avoiding harsh ultrasonic cleaners for fragile or older settings, and having professional jewellers inspect the prongs and mountings annually.
