Engagement Ring Shapes – and the Celebrities who Love Them

If you’ve read how to choose an engagement ring and now you’re sussing out engagement ring shapes, you might like to look to the creme de la creme of the jewels themselves – on the hands of the A listers who can afford them.


The round cut diamond is by far the most popular shape throughout the world accounting for more than 70% of all diamonds sold.  It is symmetrically balanced in shape and the level of light performance displayed by modern round brilliant cuts surpasses any other.

Mila Kunis, Miley Cyrus, and Alison Brie all “rock” the classic round-cut engagement rings.

After two years of dating, Ashton Kutcher presented Mila Kunis with a classic solitaire style ring with a center diamond, estimated to be around 5 carats and worth upwards of $250,000. The diamond is a round cut solitaire set in platinum with a band featuring semi pave inlay.


A perfect round diamond has 58 facet cuts divided among its crown, girdle and pavilion. The crown is the top of the diamond, the girdle the widest part and the pavilion is the base. The main aim is to achieve a diamond with maximum fire and overall perfection.

Emerald Cut

Beyoncé, Mariah, Carey, and Amal Aladdin (George Clooney’s wife) tote epic emerald-cut diamonds.  Originally developed as a cut for, you guessed it, the emerald – the cutting style was so successful with emeralds that it was soon picked up by diamond cutters.

Jay-Z took Queen Bey’s advice and “put a ring on it” – a very expensive one at that!  The rapper worked with Lorraine Schwartz to create an 18 carat flawless emerald cut diamond, valued at more than $5 million!


But it’s Mariah Carey’s emerald-cut stone which tilts the scales at 35 carats…


What makes the emerald cut for diamonds so special is that the square and rectangular cut shapes have well defined corners along with rows of facets which almost always run parallel to the girdle producing spectacular colours. They tend to act as mirrors showing a reflection in the diamond especially in colourless stones.

The emerald cut, also known as step cut usually has 57 facets. Because of the angle, size and shape of the facets the emerald cut shows less brilliance and dispersion than other brilliant and modified brilliant cut diamonds.


Kate Bosworth, Hilary Duff, and Snooki are three princesses with princess-cut diamonds to match.  When it comes to engagement rings, it is without doubt one of the most sought-after choices after the round cut.


Hilary Duff may no longer be hitched to her former sweetheart hockey player Mike Comrie, but when he popped the question, Comrie gave Duff a sparkly 14-carat princess-cut stone worth a reported $1 million.

Cushion Cut

Kim Kardashian, Bar Refaeli, and Sofia Vergara’s hubbies all proposed with cushion cut diamonds.  In the US market, the cushion cut is making waves in the jewellery industry with  a recent surge of interest in this shape and dealers seeing increasing demand.


Kardashian’s “kushion-kut” ring weighs in at an impressive 15 carats and set Kanye back a cool $8 million.

Cushion cut diamonds are also named the “pillow-cut” diamond. The cushion-cut is an antique style of cut, and it is known for having a deep cut with large facets. These large facets are what bring out the sparkle and brilliance when the diamond is exposed to light.

Asscher Cut Diamonds

A-listers Jessica Alba and Gwyneth Paltrow both love the Asscher cut diamond (perhaps Gwynny not so much anymore – who wore an eight-carat diamond ring with pave halo from Chris Martin before their “conscious uncoupling”).



Art consultant Will Kopelman proposed to his partner, Drew Barrymore, with a 4-carat radiant cut engagement ring. Its French-set band brings art deco appeal, for a style that’s as unique as she is.


This square or rectangular cut combines the quality of the emerald shape diamond with the brilliance of the round The original radiant cut had 61 facets, excluding eight girdle facets. The ideal proportions of a radiant cut diamond are generally considered to be when the length of the diamond is about 1½ times greater than its width.

Oval Cut Diamond

Blake Lively, Julianne Hough, and Kate Middleton wear oval cut diamond engagement rings, so I’ve included a few coloured engagement rings – a la Duchess Catherine.


Marquise Diamond

Both Victoria Beckham and Catherine Zeta Jones “rock” the marquise gemstone


The marquise diamond is shaped like a rugby ball or a pointed chocolate. The facets have to be cut with precision in order for the stone to have that brilliant sparkle. Failure to do this correctly will result in dark areas across the finished diamond. This is a beautiful shape and works well with smaller diamonds surrounding it.

This dark area is called a bow tie effect and looks exactly like a bow tie you would wear to a cocktail party. It is found in most fancy cut diamonds – pear, marquise, oval and hearts. It exists in all of these cuts but can be minimized so that its almost non existent with precision cutting.


 Pear Shaped

“It’s ridiculously big,” Katherine Heigl told Cosmopolitan when asked about her engagement ring!


Victoria Beckham features again with a 15 to 17-carat pear-cut diamond – her second special sparkler from David!


This one might be a little smaller than Ms Posh’s pear, but it’s just as special.
