    Grace Kelly is synonymous with Old Hollywood glamor, and her engagement ring is a perfect example of why. Before the American actress wed Prince Rainier III of Monaco in 1956, the royal presented her with the most expensive engagement ring of all time. The impressive Cartier sparkler was a 10.48-carat emerald-cut flanked by two baguette-cut side stones. According to Jewellry Box, this celebrity engagement ring is worth an estimated $38.8 million today.

    Just like her wedding dress would go on to inspire countless brides around the world, Grace Kelly's engagement ring did the same. Similar styles have been worn by celebs like Amal Clooney, Jennifer Lopez, Kim Kardashian and Liz Taylor.

    Interestingly enough, that wasn't the only engagement ring the Princess of Monaco owned. Before she wore the emerald-cut sparkler, her fiancé gifted her a Cartier eternity band with heirloom rubies and diamonds, which symbolized his home country's flag. While we don't know the official story behind this lesser-known ring, some say it was meant to be a stand-in until the second was commissioned.

    Jackie Kennedy Onassis' Engagement Ring

    Long before toi-et-moi engagement rings became a mainstream trend, Jackie Kennedy received a two-stone sparkler from John F. Kennedy. But believe it or not, that wasn't the most expensive engagement ring she owned. Following the tragic death of her first husband, Jackie Kennedy would go on to marry Aristotle Onassis in 1968—one of the world's richest men at the time. He proposed to the former first lady with a jaw-dropping 40-carat Lesotho III diamond ring from Harry Winston. The celebrity engagement ring ultimately sold for $2.6 million at an auction in 1996. Today, it's estimated to be worth around $22 million.

    Mariah Carey's Engagement Ring

    Mariah Carey was once the owner of one of the most expensive engagement rings of all time. When the singer got engaged to Australian billionaire James Packer in 2016, he presented her with a massive 35-carat diamond engagement ring set on a platinum band. Seemingly inspired by Grace Kelly's famous engagement ring, Carey's sparkler featured an emerald-cut center stone flanked by baguette tapered side stones. It was designed by Carey's close friend, jeweler Wilfredo Rosado. Shortly after news of the proposal went public, Rosado told Vogue that this celebrity engagement ring was "the most challenging piece of jewelry I've ever designed."

    When Carey and Packer split in October of that year, the famed songstress kept the bauble as part of their settlement. Although she sold it in 2018 for $2.1 million, experts say its actual value is around $10 million.

    Elizabeth Taylor's Engagement Ring

    Of all of Hollywood icon Elizabeth Taylor's iconic jewelry, her gigantic diamond from Richard Burton takes the cake for the largest and most expensive rock she ever received. It wasn't technically an engagement ring, since Taylor and Burton were already married at the time of its purchase. In 1968, four years into their marriage, he bought her the Krupp diamond: a 33.19-carat Asscher-cut stone that once belonged to actress Vera Krupp. Burton paid $305,000 for this famous engagement ring at the time, but in 2011 it was sold by Christie's for a whopping $8.8 million.

    Beyoncé's Engagement Ring

    Renowned celebrity jeweler Lorraine Schwartz designed Beyoncé's 24-carat emerald-cut diamond engagement ring with a platinum split shank, which she received from her husband Jay Z. Beyoncé's flawless ring is estimated to cost about $5 million.

    Jennifer Lopez's Engagement Ring

    Jennifer Lopez has been the lucky wearer of some of the most expensive celebrity engagement rings of all time, but we're particularly obsessed with her latest from Ben Affleck. The actors were famously engaged in 2002, though they split just days before the wedding. Jennifer Lopez's first engagement ring from Ben Affleck was a 6.1-carat pink diamond ring designed by Harry Winston. Since pink diamonds are one of the rarest shades in the world, the ring was estimated to be worth about $2.5 million.

    When Affleck proposed again in 2021, he popped the question with another rare diamond, this time in a shade of green. Jennifer Lopez's current engagement ring is a green square-shaped center stone, flanked by white trapezoid diamonds on either side. Jenny Luker, president of Platinum Guild International USA, said the estimated price is around $5 million.

    Kim Kardashian's Engagement Ring

When it comes to the most amazing celebrity engagement rings, this one has certainly earned its spot at the top.

At approximately 15 carats, this dazzling engagement ring is estimated to cost between $2 million and $4 million.

    Paris Hilton's Engagement Ring

    The stars may be blind, but you will be too after staring at Paris Hilton's engagement ring. The socialite has worn a few expensive wedding rings throughout her life, but we're partial to her sparkler from Carter Reum. When the author proposed in February 2021, he presented Hilton with a stunning emerald-cut engagement ring flanked by baguette-cut and trapezoid accent diamonds. The 20-carat ring is estimated to be worth about $2 million.

    This celebrity engagement ring was designed by Jean Dousset, the great-great-grandson of Louis-Francois Cartier. In an interview with The Knot, Dousset exclusively shared more about the inspiration for this notable celebrity engagement ring. "The one key element of this ring was that Carter was heavily invested [in the process] so that he could add as much sentiment as possible in the idealization and crafting of the ring," he told us. "His focus was on how many details and personal touches, big and small, that he could add to the ring to represent how much he loves Paris. We tend to mostly work with sentimental clients that want to create and present an engagement ring full of symbols."

    Meghan Markle's three-stone diamond engagement ring from Prince Harry weighs approximately 6 carats and is estimated to cost $350,000.

The center stone is also flanked by two smaller diamonds sourced from a brooch in his late mother Princess Diana's personal collection.
