Gaining almost 30k more posts is the marquise cut, which is a very flattering shape featuring a narrow stone with a point at each end.
When Catherine Zeta-Jones and Michael Douglas got engaged in 1999, he proposed with a vintage 10-carat side-set marquise diamond ring estimated to be worth an eye-watering £310,000 to £335,000. Meanwhile, Victoria Beckham's first engagement ring from David was a three-carat marquise-cut diamond ring with a yellow gold band.

Similar to emerald cut diamonds, rectangular radiant stones are a brilliant diamond cut with plenty of facets. With its sparkling features, we're not surprised it has been worn by celebs such as Jennifer Lopez, who was given a six-carat radiant-cut pink diamond by Ben Affleck in 2002.

One of the most easily recognisable rings is the pear cut, also known as the teardrop or pendeloque cut. As well as Cardi B's 8-carat diamond with a pink diamond halo, estimated to cost $500,000, Emily Ratajkowski and Kaley Cuoco have also received stunning pear-shaped diamonds from their loved ones.
5. Oval (161,752 total posts)
Jennifer Aniston's ring from Justin Theroux
Oval diamonds are less traditional but more flattering than a round diamond and are supposedly best suited to trilogy rings. If you're not already sold on the breathtaking cut, then Blake Lively and Jennifer Aniston's beautiful diamonds should convince you it's one to consider.
4. Round (191,558 total posts)
Her Majesty's round engagement ring
Round diamonds are among the most expensive that money can buy, according to the research. So who owns one? As well as Natalie Portman and Mila Kunis, Queen Elizabeth II also has this timeless cut, with the monarch's ring made from diamonds handed down from the Duke of Edinburgh's mother.

The Duchess of Sussex's trilogy engagement ring from Prince Harry
Another favourite among the royals is the cushion cut, which Meghan Markle owns. Her trilogy ring was composed of a cushion-shaped diamond from Botswana flanked by two side stones from Prince Harry's mother Princess Diana's personal collection.
This style is square and perfectly symmetrical with rounded edges, and they are known for their sparkle.
2. Princess (204,389 total posts)
Penny Lancaster sporting her sparkling princess-cut diamond engagement ring
Known for their geometric, square shape, princess cuts tend to look bigger than round diamonds of the same carat.
Rod Stewart presented Penny Lancaster with a sparkling princess-cut diamond engagement ring set on a platinum band studded with smaller diamonds when he proposed.
1. Emerald (342,575 total posts)
One of Victoria Beckham's engagement rings
The clear winner is the emerald cut diamond! Rectangular and strong, the emerald cut is presumably so popular because of its clarity and purity – so we're not surprised by Beyoncé's 24-carat diamond, and Gwen Stefani's large rock estimated to be worth $500,000.
Several of Victoria Beckham's whopping fourteen rings are also emerald cut, including one diamond with side baguettes she was pictured wearing in 2003, and another yellow diamond set in a yellow gold pave band she was often spotted with in 2006.
