FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric symmetry, clean lines, strong colour contrasts, and the frequent pairing of diamonds with vibrant gemstones like sapphires, rubies, and emeralds.

These pieces traditionally utilised a combination of platinum and gold, often with a platinum setting to enhance the brilliance of diamonds and secure intricate millegrain detailing, supported by an 18-carat gold band.

Authentic pieces typically feature period-specific gemstone cuts such as old European or single cuts for diamonds, hand-crafted platinum settings, makers marks, and signs of genuine age such as light surface wear on the metal.

Antique rings can be worn as standalone statement pieces or stacked with contemporary minimalist bands to create an eclectic contrast between historical craftsmanship and modern design.

To preserve these delicate items, store them individually in soft-lined boxes, remove them during rigorous physical activities, and clean them gently using warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners.
