This Art Deco engagement ring dates from circa 1930 and belongs to the jewellery category. Fabricated from platinum, the piece presents a silver-coloured finish with a polished surface. The design incorporates a single old mine cut diamond of 0.94 carats secured in a four-prong claw setting, accompanied by geometric and spear-shaped shoulders along the slender band. The visual elements include a cushion-shaped diamond with facets, parallel grooves on the shank, and stepped shoulders. The diamond measures 5.65 x 5.61 mm and sits 5.9 mm from the finger, while the overall dimensions of the item are 30 cm high, 25 cm wide, and 5 cm deep. In a contemporary home setting, this ring serves as a personal accessory worn on the hand. The platinum band wraps around the finger, positioning the central diamond outward for display. Daily storage involves placing the ring in a jewellery box or dish when not being worn.

FAQs

Art Deco engagement rings from the 1930s are characterised by geometric lines, streamlined metalwork, and the widespread use of platinum or white gold to highlight white diamonds.

These rings were predominantly crafted using platinum or 18ct white gold, set with hand-cut diamonds such as old European cut or old cushion cut stones.

Authentic old cut diamonds feature smaller table facets, open culets, and steeper crown angles than modern brilliant cuts, alongside period-appropriate hallmarks or maker marks inside the band.

An Art Deco solitaire ring can be worn alone as a focal piece or stacked alongside slim contemporary platinum bands for a subtle blend of historic and modern design.

Clean the ring using warm water, mild soap, and a soft-bristled toothbrush. Avoid abrasive chemicals and store the piece individually to prevent gemstones and settings from scratching.
