FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric precision, symmetry, streamlined silhouettes, and a strong emphasis on contrasting gemstones like blue sapphires and diamonds set in platinum.

Pieces from this era typically utilise platinum or white gold to enhance the icy brilliance of the diamonds, often featuring bezel, prong, or intricate milgrain settings designed to maximise light capture.

Authentic pieces exhibit period-specific craftsmanship such as hand-cut old European or old mine diamonds, hand-forged platinum work, natural unheated sapphires, and subtle signs of age-related wear under magnification.

An antique ring serves as a striking focal point and can be worn alone as a statement piece or paired with minimalist contemporary jewellery to create a curated, eclectic aesthetic.

Antique jewellery requires gentle cleaning using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners, and professional annual checks of the prongs to ensure the stones remain secure.
