Description

Exceptional Art Deco Platinum Diamond Solitaire Engagement Ring - 1.44ct AnchorCert Certified

This exquisite Art Deco platinum solitaire diamond ring is an exceptional piece of early 20th-century jewellery — elegant, timeless, and truly captivating.

At its heart rests a magnificent 1.44 carat round brilliant cut diamond, certified by AnchorCert Gem Lab. The stone is bright, full of fire, and full of life, possessing the sort of natural brilliance that can only be found in fine vintage diamonds.

Set in a graceful corbeille mount, the principal diamond is perfectly complemented by two sleek baguette-cut diamonds at each shoulder, adding geometric balance and a touch of architectural poise that is so characteristic of the Art Deco period.

This ring is not only beautiful but also impeccably made, and it carries the enduring charm of an era known for style, sophistication, and modern elegance.

It would make a truly breathtaking engagement ring or heirloom gift for someone with an eye for the exceptional.

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 jewellery from the 1920s and 1930s is characterised by geometric symmetry, clean linear forms, and the refined use of platinum to highlight white diamonds.

Rings from this period were predominantly crafted from platinum or white gold, frequently incorporating round brilliant or old European cut diamonds paired with baguette-cut accent stones.

Authentic pieces feature period hallmarks, precise geometric settings such as stepped or baguette shoulders, and fine hand-finished claw settings beneath the central stone.

The streamlined profile of an Art Deco diamond solitaire pairs seamlessly alongside unadorned platinum wedding bands or contemporary minimalist jewellery.

Clean the setting periodically using warm water, mild liquid soap, and a soft brush, while ensuring annual professional checks on claw tightness and stone security.
