Art Deco 2.01 Carat Old Cut Diamond Engagement Ring, French, Circa 1920

It’s almost impossible finding antique diamonds and high quality as this. The old European cut – graded by IGI, Antwerp as G colour, VS2 clarity – is utterly glowing with fire and brilliance.

FAQs

French Art Deco jewellery from the 1920s is characterised by geometric structure, refined platinum metalwork, and precise gem-setting techniques. Moving away from the soft curves of the Edwardian era, craftspeople emphasised symmetrical shapes, clean lines, and high-quality diamonds.

Rings from this period were predominantly constructed using platinum or 18ct white gold to achieve a crisp silver-toned aesthetic. Central stones were typically old European cut or transitional cut diamonds, hand-faceted to maximise sparkle under soft light.

Authentic pieces frequently bear French assay marks, such as the Dogs Head stamp for platinum or the Eagles Head for gold. Additionally, hand-cut old European diamonds exhibit small table facets, steep crowns, open culets, and slightly irregular proportions consistent with manual lapidary work.

A classic Art Deco solitaire ring features clean lines that complement both contemporary minimalist tailored clothing and vintage attire. The understated monochrome appearance allows it to stack alongside geometric platinum bands or stand alone as a single focal point.

Maintain the piece by soaking it periodically in warm water mixed with mild washing-up liquid and gently brushing with a soft toothbrush. Professional jewelers should inspect the claws annually to ensure the central gemstone remains secure.
