FAQs

Art Deco jewellery, prominent from the 1920s to the 1940s, is characterised by geometric symmetry, clean lines, stylised motifs, and a strong architectural influence.

These pieces typically feature platinum or white gold settings combined with hand-cut diamonds, frequently utilising old European or single cuts.

Authentic pieces often display hand-beaten settings, milgrain detailing, natural diamond inclusions consistent with older cutting techniques, and period hallmark stamps.

An antique ring provides a striking focal point and can be worn alone as a statement piece or paired alongside modern minimalist bands for a mixed-era aesthetic.

Regular inspection of the claw settings and milgrain by a professional jeweller is recommended, alongside gentle cleaning using warm soapy water and a soft brush.
