FAQs

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

Platinum became the dominant metal during the Art Deco period due to its strength and ability to hold fine millegrain detailing, typically set with old cut diamonds and accented with calibre-cut coloured gemstones.

Authentic pieces often feature hand-cut diamonds such as old European or old mine cuts, hand-carved platinum settings, makers marks, and period-appropriate wear consistent with age.

An antique ring can be worn as a standalone statement piece or paired with contemporary minimalist bands to create a balanced, high-contrast everyday look.

Vintage platinum jewellery should be cleaned regularly with warm soapy water and a soft brush, and inspected annually by a professional jeweller to ensure the stone settings remain secure.
