FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric precision, symmetrical designs, and a strong emphasis on contrasting materials such as platinum and diamonds.

French jewellers of this period frequently utilised platinum for its strength and ability to hold intricate settings, often paired with yellow or white gold, alongside brilliant cut diamonds.

Authentic pieces typically feature period-specific gemstone cuts such as old European or transitional cuts, hand-crafted millegrain detailing, and authentic French hallmarks stamped on the metal.

An antique solitaire ring serves as a focal point when worn alone or can be paired with minimalist contemporary bands to create a balanced, layered look.

Regular cleaning with warm soapy water and a soft brush helps maintain the brilliance of the diamonds, while periodic professional checks ensure the security of the settings.
