From custom-cut stunners to historic heirlooms, these are the biggest and most dazzling diamond engagement rings sported by A-listers
If engagement rings were accurate predictors of happily-ever-after, Hollywood couples would never split. Of course, reality works differently—but when it comes to celebrity engagements, subtlety isn’t part of the vocabulary.
Hollywood royalty (and actual royalty) don’t just whisper their love stories; they announce them with spectacular diamonds flashed across red carpets, Instagram feeds and, occasionally, yachts in Capri. These rings are not mere tokens of affection but branding statements worth millions, often accompanied by bodyguards and paparazzi lenses.
From Taylor Swift’s vintage sparkler to Lauren Sánchez’s colossal oval diamond and Mariah Carey’s legendary emerald-cut, here’s a look at the biggest, brightest and most bank-breaking celebrity engagement rings to ever grace a famous finger.
In case you missed it: The “unparalleled” value of diamond engagement rings is reserved for a select few
1. Taylor Swift

Taylor Swift’s engagement to NFL star Travis Kelce in August 2025 was pure theatre. The singer announced it on Instagram with her trademark wit—“Your English teacher and your gym teacher are getting married”—alongside photos from their garden proposal.
Her ring, designed in collaboration with Kindred Lubeck of Artifex Fine Jewelry, features a rare old mine brilliant-cut diamond in a gold bezel setting. Estimates place its value at up to US$5 million. Lubeck, who pivoted from law to jewellery in 2023, has quickly become a name to watch in celebrity circles.

2. Lauren Sánchez-Bezos

Lauren Sánchez has rewritten the rulebook on what it means to be a fiancée in the age of private rockets and trillion-dollar fortunes. When Jeff Bezos proposed in 2023, he slipped a 20-carat cushion-cut pink diamond onto her finger— valued between US$2.5 and US$3 million.
But Sánchez later revealed an even bigger upgrade: a D-flawless oval diamond weighing over 45 carats, with estimates exceeding US$5 million.
3. Mariah Carey

Leave it to Mariah Carey to redefine the meaning of a “rock.” When billionaire James Packer proposed in 2016, he did so with a 35-carat emerald-cut diamond so enormous it practically had its own entourage. Valued at US$10 million, the ring was less an accessory than a declaration. Not of love but more of wealth, of power and of Carey’s singular ability to turn every life chapter into a headline-worthy spectacle. Though the engagement fizzled, the ring remains immortal in the celebrity jewellery canon: a glittering reminder that when it comes to Mariah, more is always more.
4. Beyoncé

When Jay-Z proposed to Beyoncé in 2008, he didn’t just give her a ring. Instead, he offered a future artefact. The 18-carat emerald-cut flawless diamond, designed by Lorraine Schwartz, is valued at around US$5 million and sits firmly in the realm of legend. Sleek, architectural and utterly commanding, it mirrors the couple’s empire-building trajectory: not just jewellery but a symbol of power, permanence and pop-culture sovereignty.
5. Jennifer Lopez

Few celebrities have turned engagement rings into a personal anthology quite like Jennifer Lopez. Choosing one to feature on this list of engagement rings is quite a challenge.
Her 2019 proposal from baseball legend Alex Rodriguez came with a 15 to 20-carat emerald-cut diamond. It was glittering proof of their headline-grabbing romance, and the ring itself was valued at US$1.8 to US$5 million. However, it was her rekindled love story with Ben Affleck that gave her the most storied piece yet: an exceptionally rare 8.5-carat natural green diamond, accented with trapezoid side stones. Estimated at US$5 to US$10 million, the ring isn’t just a gemological marvel. The colour is reportedly Lopez’s lucky hue and it turns “Bennifer 2.0” into a full-circle fairytale, sealed with one of the most elusive stones on earth.
6. Elizabeth Taylor

Another woman with her collection of engagement rings, Elizabeth Taylor reportedly did have one true love: Richard Burton, who gifted the superstar with the 33.19-carat asscher-cut Krupp Diamond. It was less a ring and more a legend. Taylor wore it almost daily, proving that for her, diamonds weren’t just red-carpet props but part of her identity. When it finally went to auction in 2011, it fetched US$8.8 million, cementing its place in both Hollywood and jewellery history.
7. Serena Williams

Alexis Ohanian didn’t just propose. He staged a spectacle worthy of Serena Williams herself. The Reddit founder slipped a 12-carat emerald-cut diamond, valued at US$2 million, onto the most powerful hand in tennis. The ring is a proclamation of precision, luxury—and a reminder that even off the court, Williams sets the terms of the game.
8. Grace Kelly

When Grace Kelly traded Hollywood for Monaco, Cartier provided the perfect parting gift: a 10.5-carat emerald-cut diamond, flanked by baguettes and valued at US$4 million then and north of US$40 million today. The ring wasn’t just a jewel; it was a co-star, gleaming both on her finger and in her final film, High Society. A piece of cinema turned into dynastic iconography. Seventy years later, the rock is still making jaws drop.
9. Blake Lively

By the time Ryan Reynolds slipped a 12-carat light pink oval diamond onto Blake Lively’s finger, the couple had already perfected their now-signature rom-com chemistry—equal parts swoony and irreverent. Set in rose gold and reportedly worth around US$2 million, the ring was an early influencer of pastel-hued gemstones, helping to launch a blush-toned luxury trend that still lingers in celebrity jewellery cases today. Much like their marriage, the jewel walks the line between classic Hollywood romance and self-aware sparkle: big, pink and impossible to ignore.
10. Georgina Rodriguez

Cristiano Ronaldo made a gigantic statement with the ring he presented to long-time beau Georgina Rodriguez. At its centre is a lavish oval-cut diamond estimated between 30 and 40 carats, flanked by two oval side stones of about a carat each. Expert valuations place its worth between US$3 million and US$5 million, with some estimates soaring even higher.
Rodríguez’s debuted the rock on Instagram, with the caption: “Yes I do. In this and in all my lives.” More than the size, the ring’s every angle is engineered to catch light—and attention.
