FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric symmetry, clean lines, stylised motifs, and the prominent use of platinum paired with diamonds and vibrant coloured gemstones.

Master jewellers of the 1920s predominantly utilised platinum for its strength and fine-setting capabilities, often combining it with old European or single-cut diamonds and natural unheated sapphires sourced from regions such as Ceylon.

Authentic pieces typically exhibit hand-carved milgrain detailing, open-work gallery construction, hand-cut gemstones consistent with the period, and occasionally makers marks or purity stamps appropriate to the 1920s.

Historic cocktail rings serve as focal points when worn alone on the hand or contrasted thoughtfully with minimalist modern bands to highlight their intricate historical craftsmanship.

Preserve the integrity of the setting by storing the piece in a lined box, avoiding harsh ultrasonic cleaners on delicate antique prongs, and having a professional jeweller inspect the mounting annually.
