FAQs

Art Deco diamond jewellery from the 1920s and 1930s is defined by geometric motifs, precise stone setting techniques, and the frequent pairing of platinum tops with yellow gold bands.

These rings commonly utilised 18ct yellow gold, platinum, and diamonds, with platinum chosen for its structural strength and white finish that enhances diamond brilliance.

Authentic pieces feature period hallmarks, platinum-faced mountings on gold shanks, and period stone cuts such as old European or single cut diamonds.

An Art Deco ring can be worn as a standalone focal piece or paired alongside minimalist contemporary jewellery and neutral modern tailoring.

Clean the piece using warm water, mild soap, and a soft-bristled brush, ensuring periodic professional checks of the claws and settings.
