FAQs

Art Deco jewellery, prominent from the 1920s to the 1930s, is characterised by geometric precision, stylised motifs, and a strong architectural influence, often contrasting precious white metals with yellow gold.

Rings from this era frequently utilised a combination of platinum or white gold for settings to enhance the brilliance of diamonds, paired with yellow gold shanks, alongside hand-cut natural gemstones.

Authentic pieces feature hand-cut stones with smaller tables, higher crowns, and larger open culets compared to modern brilliant cuts, often accompanied by period hallmark stamps and hand-finished setting details.

An antique ring pairs effectively with both minimalist modern attire to allow the piece to stand out, or stacked alongside contemporary bands for a curated, mixed-era aesthetic.

Preserve vintage rings by cleaning them gently with warm soapy water and a soft brush, avoiding harsh chemical dips, and having the prong settings inspected periodically by a professional jeweller.
