Vintage 0.36 Carat Old Cut Diamond Three Stone Ring, Circa 1935

1920 - 1940
Description

An absolutely gorgeous late Art Deco diamond ring. The ring features an old European cut diamond in the centre, flanked by a pair of smaller eight-cut diamonds, with a further 12 rose cut diamond in the platinum head of the ring. Delicate hand finished details - the finely pierced gallery; the scalloped shoulders - add class to an already very pretty and well proportioned ring.

Cut:  Old European in the centre. The two main diamond either side are eight-cuts. The smaller diamonds are rose cuts.

Colour:  The centre is G. The remaining diamonds range from G to I.

Clarity:  The centre is VS2. The remaining diamonds range from VS2 to SI2; all are clean to the naked eye.

Carat:  The centre diamond is approximately 0.25 carat, with a total approximate diamond weight of 0.36 carat.

Circa:  1935.

Size:  O 1/2 (UK) or 7 1/4 (US). Free sizing available.

Measurements:  The head of the ring is 13.8 x 7.0mm and sits 5.0mm from the finger.

Weight:  2.17 grams.

Metal:  18k white gold (French hallmark visible). The diamonds are set in platinum (French hallmark almost entirely rubbed, but tested with a Niton DXL Precious Metal Analyzer to confirm).

A vintage 0.36 carat old cut diamond three stone ring from the 1930 Art Deco period. The piece is made of platinum and 18k white gold in a silver colour, featuring an elongated boat-shaped gallery with milgrain edging, a central old European cut diamond, a pair of eight-cut side diamonds, and twelve smaller rose cut diamonds in the head.

French hallmarks are visible on the metal. The head of the ring measures 1.38 x 0.7 cm and sits 0.5 cm from the finger. This piece is suitable for everyday wear on the hand as a fine jewellery accessory, fitting modern wardrobes that incorporate vintage or Art Deco style jewellery items for formal or casual outfits.

FAQs

Jewellery from the 1930s Art Deco era is characterised by geometric symmetry, fine milgrain detailing, and the use of white metals such as platinum or white gold to showcase diamonds.

Rings from this period were commonly crafted using platinum or 18ct white gold, often set with hand-cut diamonds such as old European or single cuts.

Authentic old cut diamonds feature small table facets, high crowns, deep pavilions, and an open culet visible through the top of the stone, giving them a distinct fire under soft lighting.

A vintage trilogy ring can be worn as a standalone statement piece or paired with a slim, unadorned band in white gold or platinum to allow the detailed setting to remain the focus.

Clean the piece gently using lukewarm water, mild dish soap, and a soft-bristled brush around the setting, avoiding harsh chemicals or ultrasonic cleaners if stones are delicate.
