FAQs

Art Deco diamond rings from the 1930s feature bold geometric forms, often pairing white metals like platinum with yellow gold, and utilizing hand-cut Old European diamonds characterized by a round outline, high crown, and small table.

Jewellery from this period typically combines an 18ct yellow gold band with a platinum setting to enhance the whiteness of the diamonds, setting central natural stones alongside accent shoulder diamonds.

Authentic 1930s pieces often feature mixed metal construction, hand-carved geometric shoulder accents, millegrain edge detailing, period hallmarks, and hand-cut Old European or single cut diamonds.

An Art Deco diamond ring provides a classic accent that pairs seamlessly with contemporary tailoring, minimal modern metal jewellery, or worn alongside understated plain bands.

Clean the ring gently using warm water, mild detergent, and a soft-bristled brush, ensuring settings are periodically inspected by a jeweller to ensure the stones remain secure.
