FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric lines, symmetrical patterns, and a frequent pairing of diamonds with calibre-cut contrasting gemstones such as sapphires or emeralds.

Authentic period rings from the early 20th century typically utilise platinum for its strength and bright white lustre, alongside natural old-cut diamonds and genuine blue sapphires set by hand.

Old cut diamonds, such as old European cuts, feature smaller tables, higher crowns, distinct open culets, and hand-faceted surfaces that produce a softer, warmer candlelit sparkle compared to modern brilliant cuts.

When pairing an antique ring with modern bands, look for complementary metal types like platinum and consider low-profile nesting bands or vintage-inspired enhancers to protect the setting whilst maintaining a cohesive aesthetic.

Antique jewellery should be cleaned gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners which can damage historical settings or untreated gemstones.
