Vintage 18ct Gold Art Deco Style Plaque Ring Sapphire and Old Cut Diamond Ring

1940 - 1960
Description

An exquisite vintage ring crafted in the distinctive and much-admired Art Deco style, dating from the 1960s. This piece is a wonderful example of timeless elegance and exceptional craftsmanship.

At the heart of the design is a line of three captivating old cut diamonds, securely set in platinum collets. These are encircled by a striking geometric border, adorned with shimmering rose cut diamonds and richly coloured, fancy cut sapphires in a deep Kashmir blue.

The central old brilliant cut diamond measures approximately 3.5mm, with the flanking stones at around 3mm each. Tiny accent diamonds, approximately 1mm, complete the setting, offering a total diamond weight of around 0.60 carats (Colour: H, Clarity: SI1).

The platinum setting features intricate millegrain detailing, typical of the Art Deco era, and the ring’s shoulders are delicately embellished with additional diamonds for added sparkle. The head of the ring measures 18.8mm x 10.9mm and sits 4mm proud of the shank, ensuring it catches the light beautifully from every angle.

This ring is wonderfully comfortable on the finger, offering a secure yet flattering fit – ideal for daily wear or as a very special engagement ring.

Weight: 3 grams

Metal: 18ct gold, stamped 750

Ring size: UK L / US 6 (easily resizable)

Every single antique dealer on our platform is individually approved by our internal team. We verify their professional trade history, ethical standards, and photographic quality to ensure a secure, high-standard buying environment. Upon joining, every dealer agrees to a strict 9-point code of conduct. While issues can occasionally arise, our dealers typically resolve them swiftly and directly with the buyer.

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 plaque rings are identified by their elongated rectangular or geometric silhouette, featuring symmetry, filigree work, millegrain edging, and combinations of diamonds with vibrant coloured gemstones like sapphires.

These rings were commonly crafted using platinum or 18ct white gold to achieve a crisp silver backdrop, set with old European or old single-cut diamonds and custom calibre-cut precious gemstones.

Authentic period pieces feature hand-cut stones, millegrain borders, hand-carved filigree, period hallmarks, and distinctive stone-setting techniques such as flush calibre-cut sapphire borders rather than modern cast imitations.

An Art Deco plaque ring functions as a standalone statement piece on the index or middle finger, pairing well with tailored evening wear or clean contemporary minimalist attire.

Clean using a soft brush, mild soap, and warm water, avoiding harsh chemicals or ultrasonic cleaners which can dislodge fine millegrain or delicate filigree mountings.
