This Art Deco platinum ring, dating from circa 1920, holds a large central old European cut diamond secured by four claws within a geometric gallery. The mount contains forty-eight-cut diamonds, including a graduating line along the shoulders, alongside pierced metalwork and milgrain detailing that leads to a slender band. The silver-coloured piece measures 30 cm high, 25 cm wide, and 5 cm deep. The central diamond has an H colour and VS2 clarity rating, complemented by mounting diamonds graded F to G in colour and VS1 to VS2 in clarity. Designed for personal wear, the ring suits formal occasions and everyday accessorising alike. It brings vintage elegance to modern wardrobes and functions as a striking statement piece on the hand. The silver metalwork combines traditional milgrain work with pavé-set stones, creating a textured surface that catches the light from various angles.

FAQs

Emerging in the 1920s, Art Deco jewellery is characterised by geometric patterns, clean lines, platinum settings, and precise diamond accent placement reflecting industrial modernism.

Rings from this period frequently utilised platinum for strength and detailed work, alongside Old European cut diamonds featuring hand-cut facets, open culets, and intricate milgrain detailing.

Authentic pieces generally display distinctive Old European or mine cut diamonds, hand-engraved filigree work, geometric pierced mounts, and era-appropriate assay hallmarks.

The geometric silhouette complements modern minimalist tailoring, pairing seamlessly with contemporary platinum or white gold jewellery for a refined look.

Clean gently using warm water, mild soap, and a soft brush, ensuring regular professional inspections to verify the security of claw settings and pave mounts.
