The Sustainable Choice

Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

FAQs

Art Deco diamond solitaire rings typically feature geometric proportions, clean architectural lines, and refined platinum settings that emphasise a single central stone. Prominent during the 1920s and 1930s, these designs shifted away from ornate Edwardian floral patterns toward streamlined symmetry and metalwork precision.

Platinum was the primary metal of choice during the Art Deco era due to its strength and ability to create fine, durable claw settings without adding visual bulk. Central diamonds were frequently paired with geometric shoulder detailing, accent stones, or subtle engraving along the band.

Authentic Art Deco rings often display precise hand-engraving, millgrain edging, and historical fineness stamps or makers marks inside the shank. Examining the gemstone cut under magnification typically reveals period-specific faceting patterns, such as a smaller table and higher crown.

An Art Deco diamond solitaire pairs seamlessly with minimalist contemporary metal bands or vintage-inspired geometric eternity rings. Its neutral platinum palette and timeless central profile allow it to function as a focal point alongside modern items.

Preserve platinum and diamond jewellery by cleaning regularly with warm water, mild liquid soap, and a soft-bristled brush to remove accumulated oils. Store the ring individually in a soft fabric pouch or lined box to prevent diamond facets from contacting other surfaces.
