From elegant emerald cuts to classic round solitaires to playful pear-shaped stones, celebrity engagement rings below truly prove that diamonds are forever, even if the associated marriages didn’t last.

Read on to learn more about the most memorable superstar sparklers of all time, including Mariah Carey’s 35-carat behemoth, Beyoncé’s 18-carat bauble from Jay-Z and Kim Kardashian’s 15-carat stunner from Kanye West.

Kim Kardashian

Kanye West popped the question in 2013, presenting his reality star lady love with this 15-carat cushion-cut diamond by Lorraine Schwartz worth an estimated $2 million.

Elizabeth Taylor

Richard Burton gifted Taylor with this astonishing 33.19-carat rock — originally known as the Krupp Diamond — on their fourth wedding anniversary in 1968. Now known as the Elizabeth Taylor Diamond, it was originally purchased for just $307,000; in 2011, the magnificent stone sold at auction for $8.8 million.

Mariah Carey

Oh my, Mimi! The pop superstar accepted this Wilfredo Rosado engagement ring from Australian billionaire James Packer back in 2016, a show-stopper at 35 carats with an estimated value of $10 million. The pair called off the engagement after less than a year, however, and Carey later sold the stone for $2.1 million.

Grace Kelly

Prince Rainier III of Monaco proposed to the “Rear Window” star in 1956, presenting her with this 10.47-carat emerald-cut Cartier sparkler — and making her a princess in the process. It’s reportedly worth over $4 million today.

Kate Middleton

In 2010, Prince William proposed to the future Duchess of Cambridge with the sapphire engagement ring once owned by his mother, the late Princess Diana. Designed by Garrard, the royal sparkler features a 12-carat center stone surrounded by a halo of 14 diamonds.

Meghan Markle

Not to be outdone, Prince Harry asked “Suits” star Markle to marry him in 2017 with this three-stone stunner set on a yellow gold band. Flanking the large center stone are two smaller diamonds from Princess Di’s personal collection.

Beyoncé

Jay-Z proved he was crazy in love with the pop icon in 2008, presenting her with this 18-carat emerald-cut Lorraine Schwartz ring with a split shank. It’s reportedly worth $5 million — nothing but the best for Queen Bey.

Jennifer Lopez

Alex Rodriguez knocked it out of the park when he chose J.Lo’s engagement ring. As Page Six exclusively reported, he spent seven months shopping for her 16-carat emerald-cut rock, which is worth around $1.8 million.

Cardi B

Talk about money moves! In 2017, Offset popped the question with this 8-carat pear-shaped sparkler worth around $500,000.

Ciara

The singer’s sparkler from Russell Wilson is a level up from the rest. When the pair got engaged in 2016, Ciara slipped on this 16-carat brilliant-cut diamond nestled between two side stones; it’s reportedly worth around $2 million.

Paris Hilton

Who could forget the time the hotel heiress accidentally flung her $2 million pear-shaped ring from Chris Zylka into an ice bucket while partying in Miami? The 20-carat teardrop-shaped rock was eventually saved, but the same couldn’t be said of Hilton and Zylka’s relationship; the couple split in late 2018, less than a year after getting engaged. The “Simple Life” star kept the ring.

Victoria Beckham

The former Spice Girl has amassed a whopping 14 different engagement rings (!) over the course of her 20 years of marriage to David Beckham, but this pear-shaped sparkler she received in 2005 — which weighs in at a whopping 17 carats — definitely takes the cake.

Gabrielle Union

Bling it on! Union accepted Dwyane Wade’s proposal in 2013, along with this 8.5-carat cushion-cut gem from Jason of Beverly Hills, estimated to be worth about $1 million.

Hailey Baldwin

Before popping the question in 2018, Justin Bieber picked out this oval-cut stone from Solow & Co. weighing in at between 6 and 10 carats. The cost of Baldwin’s custom ring? Around $500,000.

Amal Clooney

The human rights lawyer accepted this 7-carat emerald-cut sparkler worth $750,000 from George Clooney in 2014. Her ethically mined ring also features two tapered baguettes at the sides.

Jennifer Aniston

The “Friends” favorite’s radiant-cut ring from Justin Theroux was no joke at 8 carats, with a reported value of $500,000. The “Wanderlust” co-stars got engaged in 2012, wed in 2015 and split at the end of 2017.

Angelina Jolie

Brad Pitt spent a whole year collaborating with jeweler Robert Procop to create Jolie’s emerald-cut ring before proposing in 2012. At 16 carats, the resulting bauble features specially cut stones that encircle the star’s finger — but it wasn’t enough to keep her and Pitt together, and the pair divorced in 2016.

Serena Williams

The tennis champ’s massive ring from Reddit co-founder Alexis Ohanian is estimated to be around 12 carats and worth $2 million. Now that’s what we call love-love.

Catherine Zeta-Jones

Michael Douglas gave the “Chicago” star the old razzle dazzle in 1999, when he presented her with this stunning antique ring from Fred Leighton. It features a 10-carat center stone encircled by 28 smaller diamonds, and is worth an estimated $1 million.

Sofia Vergara

The “Modern Family” star’s massive ring from Manganiello includes a 7-carat cushion-cut diamond surrounded by a delicate halo. It’s worth roughly $500,000.

Marilyn Monroe

Joe DiMaggio skipped the traditional solitaire when selecting a ring for his Hollywood bombshell in 1954, instead opting for this platinum eternity band set with 35 baguette-cut stones. Diamonds are a girl’s best friend, after all.

Mia Farrow

Frank Sinatra asked the “Rosemary’s Baby” beauty to come fly away with him in 1966, popping the question with a 9-carat pear-shaped rock. Worth $85,000 at the time, the magnificent bauble is now estimated at closer to $2 million.

Jacqueline Kennedy

In 1953, John F. Kennedy proposed to Jackie Bouvier with this unique Van Cleef & Arpels ring, comprised of a 2.88-carat diamond alongside a 2.84-carat emerald accented with tapered baguettes. The First Lady had the sparkler upgraded a decade later, adding an additional 2.12 carats worth of marquise and round diamonds for a laurel-wreath motif.

Lady Gaga

The pop star and ex Taylor Kinney may have called off their engagement before making it to the altar, but the 6-carat heart-shaped sparkler he gave her in 2015 — designed by Lorraine Schwartz, worth about $500,000 and customized with the couple’s initials — definitely deserves applause.

Kate Upton

Justin Verlander hit a home run with the rock he chose for his supermodel wife: an 8-carat round solitaire from Anita Ko that reportedly set him back $1.5 million.
