Art Deco jewellery, prominent from the 1920s to 1930s, is characterised by geometric precision, symmetry, stylised motifs, and the prominent use of contrasting materials like platinum and yellow gold.

Jewellery from this period frequently combined platinum settings to securely hold diamonds with yellow gold bands, often featuring intricate hand-engraving, millegrain detailing, and openwork galleries.

Authentic pieces typically exhibit period-appropriate hallmarks denoting metal purity, hand-cut stones such as old European or transitional cuts, and signs of genuine age and wear within the metalwork.

Antique pieces can be paired with contemporary bands for a mixed-metal stack, or worn individually as a singular focal point to highlight their historical craftsmanship against modern attire.

Regular professional inspections of the settings and prongs are essential, alongside gentle cleaning with warm soapy water and a soft brush to prevent damage to older metals and stones.
