FAQs

An old cut diamond ring from the 1920s typically features hand-faceted diamonds such as old European cuts, characteristic of the Art Deco transition period with geometric motifs and mixed metal settings.

Engagement rings from this era frequently combined yellow or white gold with platinum, utilising platinum for the prong settings to enhance the brightness and security of the diamonds.

Authentic pieces exhibit hand-cut facets with smaller tables and higher culets under magnification, alongside period hallmark stamps, hand-carved detailing, and natural signs of age-related wear.

An antique diamond ring can be styled as a standalone engagement piece or paired with minimalist contemporary wedding bands to highlight its historical craftsmanship and unique facet patterns.

Clean antique jewellery using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners which can dislodge stones in delicate historical settings, and store in a fabric-lined box.
