FAQs

Art Deco jewellery, prominent from the 1920s to the 1940s, is characterised by geometric symmetry, stylised motifs, and high-contrast combinations of precious gemstones and metals like platinum and gold.

Traditional construction often features a platinum-topped setting paired with yellow or white gold shanks, accented by old cut diamonds and calibre-cut or round sapphires, rubies, or emeralds.

Authentic pieces typically exhibit hand-cut gemstones such as old European or single cuts, hand-carved or pierced platinum settings, and natural signs of gentle wear consistent with age.

An antique cocktail or cluster ring works well as a standalone statement piece or paired with contemporary minimalist bands to highlight its historical craftsmanship.

Care involves gentle cleaning with warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners, and having the prongs professionally checked annually to ensure stone security.
