Everything you need to know about the classic cut
When Brooklyn Beckham and Nicola Anne Peltz shared the news of their engagement with a photograph on social media at the weekend (sweetly taken by Beckham's sister, Harper), the jewellery spotlight instantly fell on the sparkling emerald-cut solitaire diamond ring that Peltz was wearing.
The classically elegant cut has actually been around for centuries (it's thought to originate from the 15th century) when jewellers used it to minimise pressure when cutting emeralds, a much more fragile stone, to prevent them from chipping or breaking.
It became a hugely popular cut during the 1920s art deco movement, which favoured clean lines and symmetrical shapes. The jeweller Harry Winston adored emerald cuts for their ability to show off the exceptional quality and clarity of a diamond (with fewer facets to reflect light than other cuts, you are able to look directly into an emerald-cut stone, which would show up any flaws). Indeed, the cut has become something of a house signature, linking back to the famous Jonker I, the 125.35 carat emerald-cut diamond cleaved from the enormous 726 carat Jonker rough diamond that Winston bought in 1935.
Since then, emerald-cut engagement rings have been worn by a starry list of brides such as Elizabeth Taylor, Grace Kelly, Amal Clooney, Beyoncé Knowles-Carter, Angelina Jolie, Reese Witherspoon and Jennifer Lopez. And yes, Peltz's future mother-in-law, Victoria Beckham, has one, too - it's one of the rumoured 15 different engagement rings that David has given her throughout their 21 year marriage.
An emerald-cut diamond may be not as instantly dazzling as classic round-cut stone (they have many more facets to maximise eye-catching sparkle) but it's perfect for anyone looking for a ring that's understated, elegant and a little more unique - so Brooklyn and Nicola's choice is a brilliantly chic one.
