Provenance
This vintage sapphire and diamond three-stone engagement ring is brimming with history! Set to centre with a natural blue sapphire, elongated emerald-cut and boasting the most marvelous shade of a rich admiral blue. Claw-set in an open-back setting and flanked by sleek step-cut diamonds which compliment the proportions of the sapphire beautifully.
On either side of the sapphire are three baguette-cut diamonds, set east-to-west, six in total. These diamonds form the shoulders of the ring and elegantly slope to a solid platinum band.
The interior of the band bears a number of inscriptions including the date '2.5-41', placing this ring at the centre of a Second World War love story.
The metal is a mix of platinum and iridium - iridium was used in jewellery during the 1940s when precious metals were increasingly scarce due to the ongoing war effort. The specific alloy of 90% platinum, 10% iridium was commonly used by American jewellers. A further personal engraving is also present.
