For Sale by AC Silver
Description

A stunning, fine and impressive antique French 1.72 carat Colombian emerald and 3.51 carat diamond, platinum Art Deco cocktail ring; part of our antique emerald jewellery collection.

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

The pierced decorated setting is ornamented with a stunning feature central 1.72ct octagonal cut Colombian emerald, collet set in relief to the centre.

The emerald is flanked to either side with a stunning feature 1.43ct and 1.36ct Old European round cut diamond.

The upper and lower portions of the setting bear twelve pavé set eight cut diamonds, accented with a horizontal collet set baguette cut diamond to the centre of the linear arrangement, completing the Art Deco design.

The broad, elevated ring shoulders integrate with the main setting and blend seamlessly with the plain hallmarked ring shank.

This stunning antique emerald cocktail ring is hallmarked to the outer surface of the shank with the French maker's mark and platinum mark (dog's head), and has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

This impressive ring is supplied with two IDGL diamond grading report certificates and an IDGL diamond and gemstone grading report card, in addition to an emerald report card and certificate supplied by the Gemmological Certification Services, London*.

Its crisp design and vivid contrast also make it a distinguished way to mark personal achievements or enrich a fine jewellery collection with timeless elegance.

NOTE: * This documentation accredits the emerald originating in Colombia (Colombian) and certifies that the gemstone shows moderate amount of oil in fissures; most emeralds undergo clarity enhancements with colourless substances such as oils or resins since they contain surface reaching fissures.

'Rather than regarding inclusions in coloured stones as harmful, in small sizes and numbers that do not in any way detract from their beauty, they should be regarded as adding to desirability, for they provide identifying characteristics.'

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 from the 1920s and 1930s is characterised by bold geometric symmetry, linear architectural structures, and the prominent use of platinum alongside vibrant coloured gemstones and diamonds.

Craftsmen predominantly worked with high-purity platinum to create dense, durable settings that allowed for intricate millgrain detailing, housing brilliant-cut diamonds, baguette-cut accent stones, and central emeralds or sapphires.

Authentic French pieces typically feature official platinum hallmarks, such as the Dogs Head mark, along with hand-cut gemstone facets, period-accurate setting techniques, and characteristic geometric balance.

Statement cocktail rings can serve as a focal point for evening wear or be styled alongside simple modern tailored attire to highlight the architectural lines and rich gemstone colour.

Clean gently using lukewarm water, mild soap, and a soft brush, ensuring the piece is dried with a soft cloth. Avoid ultrasonic cleaners and harsh chemicals, as natural emeralds require delicate care to preserve their clarity.
