FAQs

Art Deco jewellery from the 1920s and 1930s is characterised by geometric shapes, clean lines, bold colour contrasts, and precise gemstone settings often featuring platinum.

High-grade platinum was the primary metal of choice, paired with diamonds and calibre-cut precious gemstones such as sapphires, rubies, and emeralds.

Authentic pieces feature French assay marks such as the dogs head hallmark for platinum, geometric panel construction, antique hand-cut gemstones, and delicate channel or grain settings.

A geometric statement ring functions as a focal point when worn individually alongside contemporary tailoring or minimalist evening wear.

Clean gently using lukewarm water, mild soap, and a soft brush, ensuring channel-set gemstones are inspected regularly by a specialist jeweler.
