The story
Why this ring gets talked about
The engagement of the then Prince Charles and Camilla Parker Bowles was announced on 10 February 2005, and they married that April. Clarence House confirmed only that the ring was a family heirloom.
It is thought to date from the 1920s and belonged to Queen Elizabeth the Queen Mother. It was not her own engagement ring.
What it means for you: emerald cuts with baguette side stones are the classic Art Deco look, and genuine 1920s and 30s rings still turn up in Hatton Garden’s antique dealers. With an emerald cut, clarity matters more than with most shapes, so see the stone before you buy.
