FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric precision, sleek lines, symmetry, and a strong influence from modern industrial design and ancient civilisations.

Jewellery from this era frequently combined platinum settings with yellow gold bands, often featuring grain or milgrain engraving alongside hand-cut diamonds such as old European or transitional cuts.

Authentic pieces typically exhibit period-correct hand-cut gemstones, traditional metal hallmarks, and microscopic signs of wear consistent with age, alongside hand-fabricated rather than mass-cast construction techniques.

An antique ring pairs well with simple, low-profile plain metal bands to highlight its intricate period setting, or with vintage-inspired eternity bands that share matching diamond cuts.

Protect antique rings by removing them during heavy physical work, cleaning them gently with a soft brush and warm soapy water, and having settings professionally checked annually for prong integrity.
