FAQs

Edwardian jewellery is characterised by the extensive use of platinum and diamonds, featuring delicate openwork, millegrain detailing, and lace-like motifs inspired by fine textiles and garlands.

Platinum became the dominant metal choice during this period due to its strength and malleability, allowing artisans to create intricate, lightweight settings that securely held precious gemstones like diamonds and sapphires.

Authentic pieces typically exhibit hand-cut gemstones, subtle hand-carved details such as millegrain edges, period-appropriate hallmarks, and natural inclusions visible within the sapphire under magnification.

An antique ring pairs effectively with contemporary minimalist bands to create a balanced mixed-era aesthetic, allowing the historic craftsmanship to serve as a focal point.

Antique rings should be stored individually in soft pouches, cleaned gently with warm soapy water and a soft brush, and inspected periodically by a jeweller to ensure the settings and claws remain secure.
