FAQs

Art Deco jewellery is characterised by geometric precision, clean architectural lines, and a preference for white metals such as platinum paired with diamonds.

Platinum became the dominant metal for high-end jewellery during this period due to its strength and ability to hold fine settings, combined primarily with diamonds.

Authentic pieces typically feature period-specific gemstone cuts, hand-crafted platinum settings, maker marks, and natural signs of age such as gentle patina on the metal.

An antique ring can be worn alone as a striking statement piece or paired with contemporary minimalist bands to highlight its historical craftsmanship.

Clean regularly with warm soapy water and a soft brush, and have the platinum settings and claws inspected periodically by a professional jeweller to ensure stone security.
