FAQs

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric precision, symmetrical designs, stylised motifs, and the frequent use of platinum paired with contrasting gemstones like diamonds and emeralds.

Pieces from this era predominantly utilised platinum for its strength and fine detailing capabilities, alongside white gold, yellow gold, old-cut diamonds, and vibrant precious stones such as emeralds, rubies, and sapphires.

Authentic pieces often feature period-specific gemstone cuts like old European or transitional cut diamonds, hand-crafted millegrain edges, open-work filigree galleries, and period hallmarks or makers marks.

Vintage cocktail and trilogy rings add a distinctive focal point to contemporary outfits and pair effectively as statement pieces alongside minimalist modern bands or worn alone for maximum impact.

Antique rings should be stored individually in soft pouches to prevent scratching, cleaned gently with warm soapy water and a soft brush, and inspected periodically by a jeweller to ensure setting security.
