FAQs

Art Deco jewellery, prominent from the 1920s to the 1940s, is characterised by geometric symmetry, clean lines, and a strong emphasis on contrasting gemstones and metals such as platinum and yellow gold.

These rings typically feature platinum or white gold settings combined with yellow gold accents, housing hand-cut gemstones secured with traditional claw or bezel settings crafted by master goldsmiths.

Authentic pieces often exhibit period-specific cut diamonds, such as old European or single cuts, hand-carved details in the metalwork, and natural inclusions visible within unheated Ceylon sapphires under magnification.

An antique cluster ring serves as a striking standalone statement piece that pairs effortlessly with minimalist contemporary outfits or can be stacked alongside delicate modern bands for a curated look.

Clean the piece gently using warm soapy water and a soft brush, avoiding harsh chemical ultrasonic cleaners, and have the prongs checked annually by a professional jeweller to secure the stones.
