FAQs

The Edwardian period, spanning from 1901 to 1914, is characterised by light, airy, and feminine designs often featuring platinum and diamonds to create a lace-like, garland effect.

Jewellers of this era frequently utilised newly developed platinum-working techniques alongside yellow gold or white gold, paired predominantly with diamonds, pearls, and precious gemstones.

Authentic pieces typically feature hand-cut diamonds such as old European cuts or old mine cuts, intricate millegrain detailing, openwork filigree, and hallmarks indicating period metal purity.

This piece can be paired alongside contemporary minimalist bands for a contrasting stack or worn as a standalone statement piece to highlight its historical craftsmanship.

Periodic professional inspection of the settings and claws is recommended to ensure stones remain secure, alongside gentle cleaning using warm soapy water and a soft brush.
