Art Deco 1.20 Carat Old Cut Diamond Engagement Ring, Circa 1935

1920 - 1940
Description

An utterly magical vintage engagement ring. This beautifully made piece features an impressively white and bright old European cut, which also benefits from being a very "spready" diamond for its weight. The stone is secured in an eight claw platinum collet with an open gallery, and sits above a smooth back-plate. On a slender platinum shank set with six (three each side) small eight-cut diamonds.

Accompanied by an independent jewellery report by IGR.

Cut: Old European cut, with eight-cuts in the shoulders.

Colour: I in the centre. J to L in the shoulders.

Clarity: The centre is SI2 (but clean to the naked eye). The smaller diamonds ares SI1 to I1 (again, all are eye-clean).

Carat: The centre is approximately 1.20 carat, with a further approximate 0.02 carat in the shoulders.

Circa: 1930.

Size: O (UK) or 7 (US). Free sizing available.

Measurements: The diamond is approximately 6.7mm in diameter.

Weight: 3.41 grams.

Metal: Platinum. Faint French hallmarks, and tested with a Niton DXL Precious Metal Analyzer to confirm.

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 engagement rings from the 1930s typically feature geometric silhouettes, platinum or white gold settings, and central diamonds cut in old European or transitional styles. They reflect the clean lines and modern design movement of the era.

Art Deco rings were predominantly crafted using platinum or 18 carat white gold to emphasize the bright white colour of diamonds. Diamonds were held in place using claw, bezel, or grain settings with small accent stones set into the shoulders.

Authentic Art Deco rings usually feature historical hallmarks indicating metal purity, period hand-cut diamonds such as old European cuts with distinct faceting, and detailed die-struck or hand-engraved shoulder mounts.

An Art Deco diamond ring functions as a timeless engagement ring that pairs seamlessly with plain or diamond-set wedding bands. Its clean architectural style complements contemporary minimalist fashion as well as formal eveningwear.

To clean an antique diamond ring, soak it in warm water with mild washing-up liquid and gently brush around the setting using a soft toothbrush. Regular checks by a professional jeweller ensure claws remain tight and secure over time.
