What defines Art Deco jewellery design from the 1920s?

Art Deco jewellery from the 1920s is characterised by geometric shapes, clean lines, and stark colour contrasts, frequently combining light gemstones with black onyx or platinum frames.

What materials were traditionally used in 1920s French cocktail rings?

Jewellers during this era predominantly favoured platinum for its structural strength and neutral lustre, paired with large coloured central gemstones such as aquamarine and contrasting accent stones like onyx.

How can one identify authentic Art Deco platinum jewellery?

Authentic pieces usually feature official French assay hallmarks, precise geometric openwork or stepped shoulders, platinum prongs, and hand-cut cushion or step-cut gemstones.

How to style this item in a modern interior?

When not worn, fine antique jewellery can be styled inside a glass display cloche, rested on a marble vanity tray, or showcased within a mirrored dressing room cabinet.

How should an antique aquamarine and platinum ring be maintained?

Clean the ring gently using warm water, mild soap, and a soft-bristled brush, avoiding ultrasonic cleaners or harsh chemicals that could loosen stone settings or damage onyx inlay.
