The 20 Most Expensive Celebrity Engagement Rings In The World

Celebrities are people just like the rest of us — except for when it comes to how much they spend on engagement rings. From Grace Kelly's impressive ring from Prince Rainier III, which is valued at $38 million today, to Hilary Duff's gorgeous $1 million ring from Matthew Koma, many celebrities definitely splash out when it comes to picking engagement rings for their partners. 

Engagement rings tend to be pricey as most feature a diamond at the center. Whether you're looking to buy a 1-carat or a 15-carat stone, if it's a diamond ring, it's bound to set you back. Many celebrities tend to opt for flawless diamonds, which are significantly more expensive, and some favor intricate designs and diamond-encrusted bands, which also raise the dollar factor. 

Here are 20 of the most expensive celebrity engagement rings, though we're sure there will always be a celebrity out there just waiting to top them all.

Prince Rainier III of Monaco married Grace Kelley in 1956. The wedding was definitely an impressive one, but the royal kicked things off in a major way with the proposal — including the $4 million ring with which he proposed, which would be valued at least $38 million these days. 

As Hello! Magazine notes, Prince Rainier III proposed to Kelley in December 1955 after meeting her at the Cannes Film Festival. The two invited 600 guests to enjoy their wedding at the Cathedral of Monaco, and a further 30 million people watched the wedding on TV. 

The monarch actually gave his wife two rings before their wedding day. In addition to the massive engagement ring we all remember, Kelly received a Cartier eternity band encrusted with rubies and white diamonds to represent Monaco's flag. These days, both are held by the House of Grimaldi (via The Telegraph).

When John F. Kennedy proposed to Jackie Bouvier he definitely did so by making a major statement with the engagement ring he gave her. As Glamour reports, the ring is made up of both a 2.84-carat emerald and a 2.88-carat diamond, and it's quite possibly legendary. 

However, it turns out that the second engagement ring Jackie Kennedy received is even more impressive than the first. Brides shares that when Aristotle Onassis proposed to the former Mrs. Kennedy five years after her first husband's death, he did so with a 40-carat Marquise cut Lesotho III diamond ring that sold at auction for $3 million years later. Luxe Digital reveals that only 18 stones were cut from the original diamond the ring was borne from, and the present-day value of the engagement ring itself would be approximately $20 million.

Mariah Carey got engaged to James Packer in 2016, and when Packer proposed to the songstress he did so with flair. When Carey and Packer got engaged, many estimated that the 35-carat ring was worth $10 million. The ring was designed by Carey's friend Wilfredo Rosado, who told Vogue that he designed the ring with a lot of intention. He explained, "I really wanted to create something for her that was about new beginnings. I wanted to give her something s.uper sophisticated and something that took away all of the embellishments that a lot of people use when they design engagement rings these days. But it is epic."

Carey and Packer never made it down the aisle, as the Australian mogul ended their relationship by October 2016. At the time, a source close to Carey told People, "They are not together right now. They split a couple of weeks ago." Carey later admitted that the two never had a physical relationship and didn't even mention her time with Packer in her memoir "The Meaning of Mariah Carey."

In the end, Page Six reveals that Carey sold her impressive engagement ring for $2.1 million to a jeweler in Los Angeles.

When Kanye West proposed to Kim Kardashian in 2013, he did so in a major way: with a massive 15-carat cushion cut diamond ring that was also a birthday present to celebrate her turning 33. Designer Lorraine Schwartz described the ring's centerpiece as a "perfect cushion-cut diamond" which was surrounded by smaller diamonds and worth approximately $8 million (via Brides).

West also gave Kardashian a second engagement ring three years later. This time around, the reality star received a 20-carat diamond ring that was worth around $1.5 million. As viewers of Kardashian's reality show "Keeping up with the Kardashians" recall, this second ring was stolen when Kardashian was robbed in Paris the same year (via Steven Stone).

In 2019, Kardashian was photographed wearing a ring that looked eerily similar to the one that was stolen, and fans asked if the ring had been returned. She clarified that Schwartz had a replica ring she that she borrowed for the shoot (via Steven Stone).

Ben Affleck and Jennifer Lopez have been engaged twice, and Affleck has gifted Lopez with extraordinary rings both times. In 2002, Affleck proposed to Lopez with a 6-carat radiant-cut pink diamond engagement ring believed to be worth $2.5 million (via Showbiz Cheatsheet).

When Affleck proposed to Lopez for the second time in 2022, he did so with a truly exceptional green square-cut diamond, which numerous experts have pointed out is a very rare diamond. Diamond expert Ilan Portugali revealed that he was part of the search for the stone when he tweeted, "Congratulations Ben and @jlo on your engagement. It was my honor to be part of this exciting journey, on a quest to source an exceptional natural gem for your spectacular engagement ring," once news of their engagement had broken (via Hello! Magazine).

Jenny Luker, the president of Platinum Guild International USA, told Hello! Magazine that the second ring is worth approximately $5 million, meaning Affleck has spent around a total of $7 million on engagement rings for Lopez.

Paris Hilton has been engaged four times, and each ring she's received has been impressive. In 2005, Hilton got engaged to Paris Latsis, who reportedly gave her 15 rings to choose from when it was time to propose. At the time, Hilton was thrilled with the prospect of marrying Latsis. She told Us Weekly, "I'm so in love and grateful to have found such an honest and loyal person" (via E! Online). Hilton ultimately ended up selecting a 24-carat ring worth $5 million (via Brides).

However, things between the two weren't meant to be, and Hilton announced later in 2005 that the engagement was off. In fact, her official statement clarified that she called off her plans to marry the shipping heir. She explained, "Over the last couple months, I've realized that this is the right decision for me" (per Brides). Ultimately, Hilton opted to auction off the ring to benefit people impacted by the devastation of Hurricane Katrina (via Fashion Magazine).

Jay-Z and Beyoncé never announced they were engaged, so when the singer began to be photographed wearing a jaw-dropping 18-carat diamond ring on that finger, fans needed to know more. However, Beyoncé later revealed to Essence that she didn't even want an engagement ring at first, let alone one so massive (via NJ.com). She told the magazine, "People put too much emphasis on that. It's just material and it's just silly to me."

In a documentary series uploaded to YouTube, Beyoncé revealed that Jay-Z proposed on December 4, 2007, which was also his birthday. The two were on a trip to Paris, and the singer took her newly minted fiancé to a Parisian cabaret to celebrate.

In 2021, Beyoncé shared a few photos that seemed to indicate she had replaced her original engagement ring with yet another gorgeous piece of jewelry. Hello! Magazine noted that the shape of the new ring was fairly unusual for celebrities, as there aren't many who wear marquise-shaped diamond engagement rings.

Jennifer Lopez and Alex Rodriguez got engaged in March 2019, and the former baseball player proposed with a ring that has been valued at being worth anywhere between $1 and $5 million dollars. As Town & Country Magazine notes, the ring is also believed to be somewhere between 10 and 15 carats.

Lopez and Rodriguez seemed thrilled with their engagement at the time, with both sharing the same photo of the ring on Lopez's hand. However, the two called off their wedding plans two years later in March 2021 after initially postponing their wedding plans in April 2020 due to the coronavirus pandemic (via Us Weekly). Two months before their announcement, Rodriguez was accused of having an affair with "Southern Charm" star Madison LeCroy, who told Page Six that the two had never had a physical relationship and had only occasionally exchanged phone calls. 

Jennifer Lopez and Marc Anthony began a relationship after she and Ben Affleck broke up in 2004. The two moved quickly, and Anthony proposed with an 8.5-carat blue diamond that Page Six estimates is worth $4 million. 

Anthony and Lopez weren't strangers to one another. In fact, they had previously dated in 1999. In her 2014 memoir, Lopez wrote that, at the time, she felt like beginning a relationship with Anthony justified the fallout from her breakup with Affleck. As she put it, "All the heartache and pain of my recent breakup couldn't have been for nothing, could it? Maybe I had to go through the bad so I could end up with the person I was meant to be with all along" (via Vulture).

The two welcomed their twins in 2008 but announced that they were divorcing three years later in 2011 (via Vulture).

Alexa Dell is the daughter of Michael Dell, the chairman and CEO of Dell Technologies. She and her fiancé, real estate investor Harrison Refoua, got engaged in 2017, with Refoua proposing with a massive 12-carat emerald cut diamond ring worth an estimated $3 million (via Yahoo!).

Hamish Shephard, the founder of Bridebook.co.uk, told The Daily Mail, "A 12-carat diamond engagement ring would likely start from $500,000, but could easily cost several million dollars based on its cut and brilliance. This engagement ring most likely cost in the range of $2-3million."

Dell and Refoua threw an engagement celebration party in May 2018, and Dell took a moment to thank their mutual friend Mary Kitchen, who set the two up on a blind date originally. The Daily Mail noted that Dell wrote to Kitchen on Instagram, saying, "Thank you for introducing me to the love of my life!" 

Ryan Reynolds and Blake Lively got married a year after dating without ever announcing they were engaged, though her impressive 12-carat oval cut diamond ring certainly got a lot of attention as she wore it to events. The Zoe Report spoke to Kathryn Money, vice president of strategy and merchandising at Brilliant Earth, about the ring. Money told the publication that the ring likely cost $2.5 million, due to "the high quality and rare characteristics of the center diamond."

Lively later told British Vogue that the ring is incredibly important to her. As she put it, "My most treasured possession is my engagement ring made by my dear friend Lorraine Schwartz because of the love and meaning it symbolizes." 

The pair held a small wedding in September 2012 in Charleston, South Carolina. The pair didn't publish any photos of the wedding itself but did share photos of the food at the wedding with Martha Stewart Weddings.

Serena Williams and Alexis Ohanian got engaged over the holidays in 2016, with the tennis star announcing the news on Reddit in a poem. As Vogue recalled, Williams explained that she and Ohanian took a surprise trip to Rome, where "At the same table we first met by chance / This time he made it not by chance / But by choice / Down on one knee / He said 4 words And r/isaidyes."

The engagement ring Ohanian gave Williams is truly impressive. Ringspo reported that the 14-carat ring is worth approximately $2 million. The two got married in 2017 in New Orleans, Louisiana, in a wedding that was described by Vogue as having "French ball–themed, 'Beauty and the Beast'–style decor." The pair's first dance was set to "Tale as Old as Time," and Williams told the publication that the city was an important choice for Ohanian. She said, "It's his favorite city besides Brooklyn. It's got a heavy European influence; it's fun and has amazing food."

When Melania Trump got engaged to Donald Trump in 2004, she was presented with a 15-carat diamond engagement ring that Donald paid an estimated $2 million for. Melania seemed pleased with both the ring and her impending nuptials, and she told the New York Post, "It was a great surprise. We are very happy together."

The Post also reported that, while speaking on "Live with Regis and Kelly," Donald explained that engagement was the next logical step for the couple. He said, "We've had a great relationship. We've been together for five years and it was really time."

DSF Antique Jewelry also wrote that 10 years after they got married, Donald gave Melania a second diamond ring. According to the jewelry pros, the second ring features a hefty 25-carat diamond and is valued at $5 million ⁠— and this second ring is the one that Melania continues to wear to this day.

Ciara and husband Russell Wilson got engaged in March 2016 and all anyone could talk about was that ring. The singer received a flawless 16-carat, brilliant-cut diamond from Wilson, and a source close to the pair shared the incredible story that went along with the proposal.

As the story was told to People, Wilson gave Ciara a list of 30 destinations they might be traveling to before surprising her by taking her to Seychelles. Her representative told the magazine that the destination was the ultimate unveiling, saying, "The biggest surprise was that Russell proposed to his new fiancée at the romantic private 'Honeymoon Beach' located on North Island."

The two began dating in 2015, and Ciara has had nothing but positive things to say about their relationship ever since. As she told Cosmopolitan in 2016, the pair made the decision to practice abstinence out of respect for Wilson's Christian faith. "We get to have really healthy conversations and focus on each other as people," she added.

Paris Hilton has received quite a few engagement rings from various suitors, and each is just as impressive as the one that came before it. In 2018, Hilton shared that she and actor Chris Zylka were engaged and nearly immediately began showing off her 20-carat, $2 million engagement ring (via Brides).

Things between Zylka and Hilton didn't end up working out, and they called off their engagement only 11 months after it began. A source told People that Hilton was the one who ended things, explaining, "The relationship moved very fast, and she realized it wasn't right for her." The source also added that Hilton was keeping herself busy by focusing on her professional pursuits, which at the time included a skincare line.

News of their breakup came after Hilton and Zylka moved back their wedding from 2018 to 2019, though at the time Hilton attributed the decision to their busy work schedules (via People).

Tom Cruise and Katie Holmes got engaged in a major way after a whirlwind romance. Cruise told reporters in Paris that he proposed early in the morning on June 17, 2005, after the pair had a midnight dinner at the Le Jules Verne restaurant on top of the Eiffel Tower.

The diamond experts at Brilliance have evaluated Holmes' engagement ring, noting that the "very unusual" ring had a 5-carat oval-shaped diamond at its center and was valued at $1.5 million (via Showbiz CheatSheet).

Ultimately, the marriage between Cruise and Holmes didn't work out. Holmes filed for divorce from her husband in 2012, requesting and winning sole custody of their daughter, Suri Cruise. Their divorce was a drawn-out battle at that time and seemed poised to reveal suspected truths about Cruise's affiliation with Scientology, though Holmes declined to release any statement condemning the religion throughout the protracted experience. As former Scientologist Mike Rinder told The Hollywood Reporter, this was a good move. He said, "Katie's been brilliant, absolutely brilliant."

When Justin Verlander proposed to Kate Upton in 2016, he did so with the help of jewelry designer Anita Ko, who helped him craft the perfect ring for Upton. As Ko later told E! News, the two wanted to create a ring that represented the love that Upton and Verlander. She said, "Justin and I collaborated on creating the most perfect one-of-a-kind ring that is rare and of exceptional quality ... just like their love."

Upton announced that she was engaged at the 2016 Met Gala, telling E! News that Verlander had proposed some time ago. She said, "I'm really excited, he asked me right before season started so we've been keeping it on the down low for quite a while." Upton debuted her ring at the Met, and Hello! Magazine reported that the ring was worth a suspected — and truly impressive — $1.5 million.

Matthew Koma presented Hilary Duff with a $1 million engagement ring when he proposed in May 2019. Town & Country Magazine asked engagement ring expert Kathryn Money to weigh on the rock and she was only too happy to provide details. Money told the publication that the cushion-cut diamond appears to be three to four carats and is valued at anywhere between $40 thousand and $80 thousand.

However, other sources indicated that the impressive rock might be worth even more. As Us Weekly reported at the time, the actual price tag on the ring might be closer to $1 million (via MTV News). Duff's representative confirmed the engagement to MTV News, telling the outlet that the proposal happened on a trip to Hawai'i and, "After having been together for over two years, they are very excited to share this happy news. They are thankful for all of your warm wishes."

When it came time to propose to Kourtney Kardashian, Travis Barker wanted to work with experts he could trust. Barker ended up working closely with Lorraine Schwartz to design the ring he gave Kardashian, with Schwartz telling People, "It's a flawless, beautifully cut diamond stone. I worked on it with Travis and he was a really big part of it."

The ring is valued at a hefty $1 million according to The Cut, and Kardashian was hysterical when she accidentally broke the engagement ring only months after receiving it. Kardashian explained in an episode of Hulu's "The Kardashians" that she sat the ring on the floor next to her while folding clothes, and "I had to get something up above in my closet, and when I stepped down, I stepped on the ring."

Happily, she was able to get the ring repaired.

Catherine Zeta-Jones and Michael Douglas got engaged in 1999 after first being introduced in 1996. Douglas reportedly proposed to Zeta-Jones at his home in Aspen, Colorado, presenting her with a vintage 10-carat marquise-cut diamond ring that is believed to have been valued at around half a million dollars (via Hello! Magazine).

Jewelry expert Kate Earlan-Charnley told Hello! Magazine that the ring was said to be inspired by the lips of Madame de Pompadour. Earlan-Charnley also commented on the ring directly, noting, "In addition to the impressive 10-carat marquise centre diamond, set east-west, is a hidden halo of diamonds with a diamond pave eternity band." 

Zeta-Jones and Douglas went on to have an impressive wedding that cost the pair around $1.5 million. The two have been open about their highs and lows in the past, with Zeta-Jones once telling WSJ Magazine that there is one secret to their long marriage. She said, "The constant is love and respect. We've never, ever lost our sense of humor, and we enjoy each other's company."
