Marilyn Monroe had it right: diamonds are a girl&rsquo;s best friend.&nbsp;

The best gifts come in the smallest boxes (at least, where jewelry is concerned). And in 2025, celebrity proposals have delivered some of the biggest&mdash;and priciest&mdash;rings yet, even by Hollywood&rsquo;s sky-high standards. We&rsquo;ve seen <a href="https://www.lofficielusa.com/fashion/everything-to-know-about-the-ronaldo-engagement-ring-cost-and-carats">Georgina Rodr&iacute;guez</a> make headlines for her massive sparkler from longtime partner <a href="https://www.lofficielusa.com/pop-culture/cristiano-ronaldo-and-georgina-rodriguez-relationship-timeline-engagement-announcement">Cristiano Ronaldo</a>. And just this week, <a href="https://www.lofficielusa.com/fashion/taylor-swift-engagement-ring-dress-shoes-watch-outfit-details">Taylor Swift</a> has dominated the spotlight&mdash;even more so than usual&mdash;after announcing her engagement to Kansas City Chiefs star <a href="https://www.lofficielusa.com/pop-culture/taylor-swift-travis-kelce-relationship-timeline-dating-football-chiefs">Travis Kelce</a>. Then, of course, there was the wedding of the year: <a href="https://www.lofficielusa.com/politics-culture/jeff-bezos-wedding-venice-protests-lauren-sanchez">Jeff Bezos</a> and Lauren Sanchez&rsquo;s <a href="https://www.lofficielusa.com/pop-culture/jeff-bezos-lauren-sanchez-wedding-venice-celebrity-guest-list">star-studded Venice celebration</a>.&nbsp;
All of this had L&rsquo;OFFICIEL wondering: which celebrities are showing off the most expensive rings? With oversized diamonds and custom designs setting the trend for 2025, it&rsquo;s clear that when it comes to engagements, more really is more.&nbsp;
Ahead, L&rsquo;OFFICIEL rounds up the most expensive celebrity engagement rings as of 2025.

<h2 style="text-align: center;">Taylor Swift</h2>

We&rsquo;ll start off strong with what&rsquo;s already being called the engagement of the year. In case you somehow missed it (you probably didn&rsquo;t), Taylor Swift announced her engagement to Travis Kelce in an Instagram post on Tuesday. And the news caps off an already monumental year for the singer: she <a href="https://www.lofficielusa.com/pop-culture/all-the-celebrities-showing-support-for-taylor-swift-buying-masters-back">bought back her masters</a> in May, <a href="https://www.lofficielusa.com/music/everything-to-know-about-taylor-swifts-new-album-release-date-the-life-of-a-showgirl-travis-kelce">announced her 12th studio album,</a> The Life of a Showgirl, just weeks ago, and now has a sparkling new ring to top it all off.&nbsp;
Swift&rsquo;s vintage-inspired ring features an old mine brilliant-cut diamond set on a gold band and is reportedly worth $550,000, according to Estate Diamond Jewelry&rsquo;s Benjamin Khordipour, who spoke to <a href="https://www.brides.com/taylor-swift-engagement-ring-cost-details-11797916" target="_blank" rel="noopener">Brides</a>. The ring, Khordipour said, is estimated at approximately eight carats with an F color grade and VS1 clarity. Still, because the specifics aren't yet known, <a href="https://www.today.com/popculture/taylor-swift-engagement-ring-cost-rcna227776" target="_blank" rel="noopener">other reports</a> say that the ring could be worth up to $1.2 million. And according to <a href="https://pagesix.com/2025/08/26/style/taylor-swift-shows-off-engagement-ring-from-travis-kelce-on-instagram/" target="_blank" rel="noopener">Page Six</a>, the vintage-inspired ring was designed by Kindred Lubeck of Artifex Fine Jewelry.

<h2 style="text-align: center;">Selena Gomez</h2>

And Swift&rsquo;s best friend, <a href="https://www.lofficielusa.com/fashion/selena-gomez-red-carpet-evolution-33rd-birthday">Selena Gomez</a>, got engaged to music producer <a href="https://www.lofficielusa.com/pop-culture/benny-blanco-justin-bieber-tiktok-song-jennifer-hudson-show-interview">Benny Blanco</a> just eight months earlier, too. Gomez also announced her engagement in an intimate <a href="https://www.instagram.com/selenagomez/p/DDdvcjbxoi1/" target="_blank" rel="noopener">Instagram post</a> back in December, captioning it simply: &ldquo;forever begins now...&rdquo;&nbsp;&nbsp;
Her ring is just as dazzling as the <a href="https://www.lofficielusa.com/pop-culture/selena-gomez-boyfriend-benny-blanco-dating-relationship-timeline">love story</a> behind it. Designed by Katherine Theofilos Claster and Stephanie Theofilos of Abril Barret, the piece features a marquise-cut diamond set on a diamond-pav&eacute; gold band. The stone is estimated to be between six and eight carats, with experts valuing the ring anywhere from $250,000 to $1 million.
Perhaps it&rsquo;s not the most expensive celebrity engagement ring compared to other stars&rsquo; massive diamonds, but it&rsquo;s nonetheless a stunning, one-of-a-kind piece that makes a serious statement.

<h2 style="text-align: center;">Georgina Rodr&iacute;guez</h2>

Then there&rsquo;s the most show-stopping of them all. Earlier in August 2025, Georgina Rodr&iacute;guez announced her engagement to Cristiano Ronaldo in a heartfelt <a href="https://www.instagram.com/p/DNOPitPoAgN/" target="_blank" rel="noopener">Instagram post</a>, writing: &ldquo;S&iacute;, quiero. En esta y en todas mis vidas.&rdquo; (&ldquo;Yes, I do. In this and in all my lives&rdquo;).&nbsp;
Her ring is nothing short of jaw-dropping: a massive oval-cut diamond set in a platinum band, estimated to be worth between $3 and $5 million. Ann Grimmett of Jared Jewelers told <a href="https://www.elle.com/culture/celebrities/a65792478/georgina-rodriguez-cristiano-ronaldo-oval-diamond-engagement-ring-explained/" target="_blank" rel="noopener">ELLE</a> that the ring is approximately 30 to 40 carats with two one-carat oval side stones.

<h2 style="text-align: center;">Lauren S&aacute;nchez-Bezos</h2>

In late June, Lauren S&aacute;nchez and Amazon tycoon Jeff Bezos tied the knot in a lavish Venice wedding, <a href="https://www.lofficielusa.com/pop-culture/jeff-bezos-lauren-sanchez-wedding-venice-celebrity-guest-list">attended by stars</a> like Orlando Bloom, Oprah Winfrey, and Kim Kardashian. The couple got engaged during a European getaway in May 2023.&nbsp;
As expected, the billionaire proposed with a ring worthy of the occasion&mdash;and the wallet. The pink cushion-cut diamond, designed by Lorraine Schwartz, is estimated to be worth between $3 and $5 million, jewelry expert Briony Raymond told <a href="https://www.vogue.com/article/lauren-sanchez-engagement-ring#:~:text=At%20first%20glance%2C%20it's%20easy,be%20a%20whopping%2030%20carats." target="_blank" rel="noopener">Vogue</a>. The roughly 30-carat center stone is set on a diamond-pav&eacute; band and framed by a double hidden halo, creating a truly show-stopping piece.

<h2 style="text-align: center;">Hailey Bieber</h2>

<a href="https://www.lofficielusa.com/pop-culture/justin-bieber-hailey-bieber-relationship-timeline">Hailey and Justin Bieber</a> got engaged in an intimate restaurant during a Bahamas trip in July 2018. While their engagement made headlines for more reasons than one, the ring was certainly one of the main focal points.&nbsp;
Bieber&rsquo;s engagement ring features an oval-cut diamond estimated between six to 10 carats, set on an 18K gold band. Designed by Jack Solow of Solow &amp; Co., the ring is valued at approximately $400,000 to $600,000.&nbsp;
And if the original ring wasn&rsquo;t already head-turning enough, <a href="https://www.lofficielusa.com/pop-culture/justin-bieber-new-album-hailey-bieber-lyrics">Justin</a> upgraded Hailey&rsquo;s ring with an even more extravagant diamond after <a href="https://www.lofficielusa.com/pop-culture/justin-hailey-bieber-announce-pregnancy-vow-renewal">announcing their pregnancy</a> during an intimate vow renewal in Hawaii last year. The new ring, designed by <a href="https://www.lofficielusa.com/fashion/lorraine-schwartz-natural-diamond-council-emerging-designer-bipoc-initiative">Lorraine Schwartz</a>, is at least one carat larger than the original and is reportedly valued at $1.5 million. Like the original, it&rsquo;s also an oval-cut&mdash;though more elongated than the first&mdash;and set in a four-prong yellow gold band.&nbsp;
Hailey sometimes wears both rings (can we blame her?), with the upgraded one on her ring finger and the original on her right pinky, though she mostly favors the newer piece. Together, the two rings are at least $1.9 million.&nbsp;

<h2 style="text-align: center;">Mariah Carey</h2>

Mariah Carey&rsquo;s is also one of the most expensive celebrity engagement rings ever. The 35-carat emerald-cut center stone, designed by Wilfredo Rasado, featured two tapered baguette diamonds on each side and was set on a platinum band. According to <a href="https://www.brides.com/mariah-carey-engagement-rings-8718461#:~:text=Unlike%20her%20public%20sale%20of,on%20their%20second%20wedding%20anniversary).">Brides</a>, it was estimated to be worth $10 million when her ex-fianc&eacute;, James Packer, proposed to her in 2016.&nbsp;
Carey continued to wear the ring shortly after she and Packer called it quits, though she eventually sold it for $2.1 million.

After Lady Gaga got engaged to Michael Polansky in April 2024, she debuted her engagement ring months later at the 2024 Venice Film Festival. The 10-carat oval-cut ring, designed by Sofia Jewelry, is set on a white and rose gold band featuring a natural pink ombr&eacute; diamond-pav&eacute; and a hidden white diamond halo.&nbsp;According to <a href="https://pagesix.com/2024/09/03/style/how-lady-gagas-engagement-ring-from-michael-polansky-signifies-a-lasting-marriage/">Page Six</a>, the ring is estimated to be worth between $500,000 and $2 million.

<h2 style="text-align: center;">Beyonc&eacute;</h2>

Jay-Z proposed to Beyonc&eacute; with an 18 to 24-carat diamond-cut ring in 2007. It features a split-shank platinum band paved with diamonds. The engagement ring was designed by Lorraine Schwartz and, according to <a href="https://wwd.com/pop-culture/celebrity-news/feature/most-expensive-celebrity-engagement-rings-1235751267/#:~:text=Beyonc%C3%A9&amp;text=Jay%2DZ%20proposed%20to%20Beyonc%C3%A9,reportedly%20cost%20around%20$5%20million." target="_blank" rel="noopener">WWD</a>, is worth around $5 million.

<h2 style="text-align: center;">Paris Hilton</h2>

It&rsquo;s no surprise that Paris Hilton owns one of the most expensive celebrity engagement rings today. After all, she did dominate the fashion and social scene in the 2000s, and of course, with her family background, it would&rsquo;ve been shocking if her engagement didn&rsquo;t include a show-stopping rock&mdash;reportedly worth $2 million.&nbsp;
The ring features three stones: a 10-carat emerald-cut center stone along with two trapezoid-shaped diamond side stones, all set on a diamond band. To top it all off, it was custom-designed by Jean Dousset, the great-great-grandson of Louis-Fran&ccedil;ois Cartier.

<h2 style="text-align: center;">Scarlett Johansson</h2>

Scarlett Johansson&rsquo;s ring is among the most unique celebrity engagement rings yet. Her husband, Colin Jost, proposed to her in May 2019 with an 11-carat pear-shaped diamond set in a dark ceramic metal band. The ring is estimated to be worth around $400,000, according to <a href="https://www.harpersbazaar.com/celebrity/latest/a28497520/scarlett-johansson-engagement-ring/" target="_blank" rel="noopener">Harper&rsquo;s BAZAAR</a>.&nbsp;&nbsp;

<h2 style="text-align: center;">Grace Kelly</h2>

We&rsquo;re saving the best for last: <a href="https://www.lofficielusa.com/fashion/grace-kelly-style-inspiration">Grace Kelly&rsquo;s</a> iconic engagement ring, custom-designed by <a href="https://www.lofficielusa.com/fashion/cartier-en-equilibre-high-jewelry-collection-launch">Cartier</a>. In 1955, Prince Rainier III proposed to Kelly with a diamond and ruby eternity band, symbolizing the colors of Monaco&rsquo;s flag. By 1956, when the couple officially announced their engagement, Kelly was wearing her 10.48-carat ring. The ring features an emerald-cut center stone with baguette-cut side stones, all set in a platinum band. Kelly even wore her ring on set for her 1956 film High Society, her final role before becoming the Princess of Monaco.&nbsp;
Originally valued at $4 million in 1956, the Cartier engagement ring is now estimated at around $38.8 million today, according to <a href="https://www.brides.com/where-is-grace-kellys-engagement-ring-8759662#:~:text=Just%20seven%20months%20after%20Prince,conference%20in%20her%20family's%20home." target="_blank" rel="noopener">Brides</a>, making it the most expensive celebrity engagement ring today.
