An Art Deco engagement ring from circa 1920, designed as a classic solitaire. The piece combines a slender 18k yellow gold band with a white metal collet, presenting a gold and clear colour palette with a polished finish. A single old mine cut diamond sits in the six-claw setting, supported by an open gallery above a tapered shank. The central diamond measures 4.95 x 4.79 mm, and the setting sits 5.4 mm from the finger, with an overall weight of 1.93 grams. This ring suits daily wear as an engagement or dress ring, worn on the hand in domestic settings. The slim profile and neutral tones allow it to pair easily with other jewellery or wedding bands. It adapts well to both traditional and contemporary wardrobes.

FAQs

Rings from the 1920s typically feature old European cut diamonds set in styles that bridge late Edwardian elegance and early Art Deco geometry. These pieces frequently showcase slender bands made of yellow gold paired with platinum or white metal settings to accentuate the diamond.

Solitaire rings from this era commonly utilised eighteen-carat yellow gold for the band paired with platinum or white gold claws to hold the central diamond securely. The combination provided structural durability while offering a neutral backing that optimized the refraction of light through the stone.

Old cut diamonds, particularly old European cuts, are distinguished by a high crown, small table, deep pavilion, and a visible flat culet at the base of the stone. Unlike modern brilliant cuts, they were hand-faceted to maximise sparkle under candlelight, resulting in a distinct optical pattern.

An antique solitaire ring pairs effectively alongside slim modern metal wedding bands or vintage-inspired eternity rings. The classic low-profile setting of a single stone ring allows it to stack seamlessly with contemporary or historical pieces.

Clean the ring gently using warm water, mild liquid soap, and a soft-bristled brush to remove dust and oil from around the claws. Periodically have a professional jeweller inspect the claws to ensure the stone remains secure.
