Antique Art Deco 2.95ct Diamond and Platinum Solitaire Ring Circa 1925

1900 - 1920
For Sale by AC Silver
Description

A stunning, fine and impressive antique Art Deco 2.95 carat diamond solitaire ring in platinum; part of our antique engagement ring collection.

This stunning, fine and impressive antique diamond solitaire ring has been crafted in platinum.

The pierced decorated setting of this antique engagement ring is embellished with a stunning principal 2.55ct transitional modern brilliant round cut diamond, claw set in relief.

The feature diamond setting is flanked with elevated ring shoulders, each embellished with three baguette cut diamonds, totalling 0.40ct, creating a balanced, tapering look across the bridge of the finger.

The beautiful hand-crafted Art Deco shoulders integrate with the main setting and blend seamlessly with the plain hallmarked platinum shank.

This stunning Art Deco diamond ring is hallmarked to the interior of the shank with the platinum mark (Pt) and the piece has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

This stunning antique ring is supplied with an IDGL diamond grading report certificate for the feature stone, in addition to an IDGL diamond grading report card for the supporting stones.

This antique diamond solitaire ring is one of the finest Art Deco examples of its type you could hope to acquire.

This 2.5 carat diamond solitaire with baguette accents in the art deco style is particularly well suited as an engagement ring for someone who appreciates antique character and geometric precision. The strong architectural setting allows the centre stone to take prominence, while the baguette diamonds add symmetry and refinement, resulting in a ring of impressive brilliance and enduring presence.

Images do not always reflect the true colour and brilliance of gemstones and diamonds. The video however provides a truer representation of the actual colour and showcases each stone in this diamond solitaire with baguettes.

Condition

This stunning antique Art Deco diamond solitaire is excellent quality, set with a stunning feature diamond displaying a fine white colour, brilliance and presence.

The impressive supporting diamonds display a fine white colour and brilliance.

The Art Deco ring is an excellent gauge of platinum and in excellent condition.

Reflections in photographs may detract from the true representation of this stunning round diamond solitaire engagement ring.

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. In fact, since our founding in 2002, Sellingantiques has only had to step in to help resolve an issue on roughly five occasions—a true testament to the quality of our dealers and their dedication to your happiness.
Our dealers are highly experienced in packing and shipping fragile, high-value antiques. Because you are in direct contact with the dealer, you will be able to easily go through all available shipping and insurance options together to ensure your item arrives safely.
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.

Art Deco jewellery, prominent during the 1920s and 1930s, is characterised by geometric shapes, clean lines, symmetry, and the contrasting use of geometric accent stones like baguette or calibre cuts.

Rings from this era frequently utilised platinum or white gold to complement the white appearance of diamonds, often featuring hand-cut baguette or calibre-cut accent stones set into claw or rub-over mountings.

Authentic pieces generally display period hallmark stamps, platinum purity marks, precise geometric shoulder settings, and hand-cut diamonds such as old European or transitional cuts.

Art Deco solitaire rings offer an enduring aesthetic that seamlessly pairs with classic wedding bands, stackable rings, or contemporary tailored attire for daily wear and formal occasions.

Clean the diamond and platinum setting using warm water, mild detergent, and a soft brush, avoiding harsh chemicals, and store the piece separately in a fabric-lined box to prevent surface scratching.
