FAQs

Art Deco jewellery, prominent from the 1920s to the 1940s, is characterised by geometric precision, stylised motifs, and a strong emphasis on contrasting colours and materials such as platinum, gold, diamonds, and precious gemstones.

Trilogy rings from this era typically combined yellow or white gold with platinum settings to securely hold diamonds and coloured gemstones like rubies, sapphires, or emeralds.

Authentic pieces often exhibit hand-cut gemstones, such as old European or old mine cut diamonds, traditional claw or millegrain settings, and period hallmarking indicative of British or international assay offices.

An antique ring serves as a focal point and can be worn alone as a statement piece or paired with minimalist modern bands to highlight its historic craftsmanship and unique silhouette.

Preserve vintage pieces by storing them individually in soft-lined boxes, removing them during rigorous activities, and having settings and stone security checked periodically by a professional jeweller.
