FAQs

Art Deco jewellery, originating in the 1920s and 1930s, is defined by geometric patterns, bold linear shapes, and contrasting gemstone combinations. Design accents such as millegrain detailing, platinum or white gold settings, and calibre-cut gemstones are hallmark characteristics of this movement.

Jewellers of the 1920s frequently paired 18ct white gold or platinum with bright white diamonds and deep blue sapphires. Platinum allowed for delicate lace-like filigree and tight geometric settings, while custom-cut calibre sapphires provided smooth, uninterrupted borders of colour.

Authentic pieces exhibit hand-applied millegrain edges, precision hand-cut calibre stones tailored to fit the specific setting, and period-appropriate hallmarks inside the band. Machine precision was minimal, so subtle variations in hand-cut facets under magnification often indicate genuine period craftsmanship.

An Art Deco sapphire and diamond ring serves as a striking statement piece that complements both minimalist tailored attire and formal evening wear. Its geometric aesthetic allows it to stand alone on the hand or sit alongside sleek contemporary bands.

Clean the setting gently using warm water, mild soap, and a soft-bristled brush to remove dust from behind the stones. Avoid harsh chemicals or ultrasonic cleaners, particularly if the mounting features delicate millegrain work or channel-set gemstones.
