There’s an endless number of celebrity engagement ring lists that showcase their striking size and price tag.
While the average couple spends about $5,000 on an engagement ring, celebrity diamonds often top $1 million.
But we were also interested if celebrities chose different shapes for their diamonds than most couples, and which were most popular.
To find the answer, I partnered with Clean Origin to analyze 250 celebrity engagement rings and their cuts.
The data ranges from King Edward’s emerald cut for the Duchess of Windsor in 1936 to 2023 engagements like Jake Funk’s emerald cut for Hannah Ann Sluss.
Here’s a breakdown of the data on the most popular shapes for celebrity engagement rings.
What are the Most Popular Shapes for Celebrity Engagement Rings?
Round Cuts
Round cut diamonds are the most popular shape for celebrity engagement rings, and the same is true for other couples. But for celebrities, they make up a smaller percentage — 30 percent — compared to non-celebrities, where estimates place round cuts at about 63 percent.
They’re the traditional style known for strong brilliance, which also helps hide inclusions and color.
Round cuts also have the highest price per carat. So the combination of a round cut and high carat weight results in the high costs attributed to celebrity diamonds.
We also found round cuts to be consistently popular over the last few decades.
For example, Barack Obama proposed to Michelle Obama with a round cut in 1991.
Emerald Cuts
Emerald cuts are the second most popular style for celebrities, with 44 out of 250 (18 percent) featuring the rectangular step-cut.
Emerald cuts have a lower price per carat compared to round cuts and other brilliant shapes, but the elongated facets cause it to appear larger than many other cuts, even if they’re the same carat weight.
The relatively high percentage of emerald cuts worn by celebrities is a deviation from other couples.
In fact, Clean Origin’s buyers only choose emerald cuts five percent of the time.
The list of celebrities who were proposed to with an emerald cut include:
- Sarah Jessica Parker (from Matthew Broderick)
- Kate Beckinsale (from Len Wiseman)
- Hayden Panettiere (from Wladimir Klitschko)
- Amal Clooney (from George Clooney)
- Beyoncé (from Jay-Z)
It’s also stood the test of time, beginning with the Duchess of Windsor in 1936 and continuing to 2023, with Cole Tucker’s proposal to Vanessa Hudgens.
Oval
Oval cuts made up 18 percent of our sample of 250 celebrity engagement rings — 45 instances in total.
The cut mimics a round diamond but is stretched in a way that makes it appear larger relative to its carat weight. From a distance, it can be hard to distinguish the two, especially if it has a smaller length to width ratio.
Its brilliant cut facets still display a high degree of white light.
You’ll often earn a 25 percent discount compared to a round cut with the same qualities.
Celebrities who rocked an oval cut include:
- Katie Holmes (from Tom Cruise)
- Blake Lively (from Ryan Reynolds)
- Julianne Hough (from Brooks Laich)
- Hailey Baldwin (from Justin Bieber)
- Kourtney Kardashian (from Travis Barker)
- Kirsten Dunst (from Jesse Plemons)
Celebrities wear oval cuts at a higher rate — 18 percent — than Clean Origin’s customers, who purchase the cut 15% of the time.
What are the Least Popular Cuts for Celebrity Engagement Rings?
Rose Cut
Rose cuts have a vintage style, featuring a domed top and flat bottom. Most have between three and 24 facets, and it’s named after how it mimics the shape of a rose petal.
In our sample of 250 celebrity engagement rings, only 2 were rose cuts:
- Lily Collins (from Charlie McDowell)
- Camila Alves (from Matthew McConaughey)
This aligns with the overall popularity of rose cuts for engagement rings. It’s a rare pick because its brilliance pales in comparison to a brilliant cut.
The wide facets on top cause light to move subtly throughout the diamond instead of returning high amounts to the viewer.
Marquise Cuts
Marquise cut diamonds are shaped like a football.
Only 3 percent celebrity engagement rings we analyzed were marquise cuts, which is 7 out of 250. At Clean Origin, less than one percent of buyers choose marquise cuts.
They’re less expensive than round cuts, so you can choose a higher carat weight for the same price, and rival its brilliance because of the triangular-shaped facets.
Celebrities who were proposed to with a marquise cut include:
- Catherine Zeta-Jones (from Michael Douglas)
- Ashlee Simpson (from Evan Ross)
- Jerry Hall (from Rubert Murdoch)
- Jackie Kennedy Onassis (from Aristotle Onasses)
Heart Cuts
Like most fancy shapes, heart cut diamonds are named after their shape.
In our survey, only 5 celebrity engagement rings were heart cuts, representing 2 percent of our total.
This more closely aligns with their appeal for other couples as well.
Celebrities with heart cut diamonds include:
- Lady Gaga (from Taylor Kinney)
- Avril Lavigne (from Mod Sun)
- Rochelle Humes (from Marvin Humes)
- Vivian Han (from Ken Chu)
- Chen Ziahn (from Dai Xiangy)
Although the shape matches the symbol of love, it’s a rare choice for engagement ring diamonds. The shape is more often seen in other pieces of jewelry like necklaces and bracelets than as the centerpiece on a ring.
Asscher Cut
Asscher cuts are tied with heart cuts on the list of least popular cuts for celebrities.
The five in our survey are:
- Gwyneth Paltrow (from Chris Martin in 2002)
- Jessica Alba (from Cash Warren in 2007)
- Kristin Cavallari (from Jay Cutler in 2011)
- Nicky Hilton Rothschild (from James Rothschild in 2014)
- Pippa Middleton (from James Matthews in 2016)
Asscher cuts are a squared version of emerald diamonds. They have an octagonal shape with a deep pavilion, giving the “hall of mirrors” illusion. It gained popularity in the 2000s, as evidenced by the several celebrities choosing it as their cut.
Conclusion
Our research on 250 celebrity engagement rings by shape has a clear conclusion: Celebrities and the rest of the population have different tastes.
As examples, round cuts are less popular among celebrities, and emerald and cushion cuts are far more popular.
Not only can they afford diamonds far more expensive than the average engagement ring, it appears their status and wealth also leads them toward a different choice in cut.
