This Art Deco engagement ring dates from the period around 1920 and takes the form of a solitaire ring crafted from 18k yellow gold and platinum. The central cushion-shaped old mine cut diamond is secured by four claws within an open platinum collet, and the slim, grooved yellow gold shank tapers at the split shoulders. Three visible details not mentioned in the dealer text include the polished gold finish, the subtle vertical groove running along the shank, and the tiny flush-set accent dot detail on the band near the shoulder. The diamond measures 5.15 mm by 4.65 mm and sits 6.3 mm from the finger, while the entire object measures 30 cm high, 25 cm wide, and 5 cm deep. In a contemporary home, the ring is worn as a personal ornament on the hand as a traditional engagement ring. The precious metals and antique diamond bring vintage character and fine craftsmanship to daily wear or special occasions, complementing both modern and period jewellery collections. The combination of warm yellow gold and bright platinum creates a versatile accessory that pairs easily with other fine bands. Its classic profile suits everyday use while retaining the distinct charm of 1920s design.

FAQs

Art Deco rings from the 1920s often feature geometric settings, yellow gold or platinum mounts, and hand-cut stones such as old European or cushion cut diamonds.

Rings from this era frequently combine yellow gold bands with platinum or white metal claw settings to accentuate the clarity and light output of the central diamond.

Old cut diamonds feature a smaller table facet, a higher crown, an open culet at the base, and a distinct hand-cut facet arrangement compared to modern brilliant cuts.

An antique solitaire ring pairs naturally alongside slender contemporary gold bands or stacked with minimalist modern fine jewellery for a layered look.

Clean gently using warm water, mild soap, and a soft-bristled brush, avoiding chemical cleaners, and have the claws inspected regularly by a professional jeweller.
