Michelle Obama: 1-carat
Amy Adams: 1-carat
Keira Knightley: 2-carat
The Game of Thrones star said yes to Joe Jonas in October 2017. Experts can't quite decide on the details of the ring, estimating it to be between 2- and 5-carats and ranging in price anywhere from $20,000 to $150,000. Regardless, the pear-cut diamond set on a double band covered in pavé stones is a stunner.
Miranda Kerr - 2.5 Carats
Lauren Conrad: 3-carat
Jennifer Lawrence: ~3-5-carats
The Oscar-winning actress' emerald-cut diamond from her art gallery director husband, Cooke Maroney, sits atop a thin gold band. According to Elle, experts placed the ring at between 3-5-carats and worth roughly $200,000. Lawrence and Maroney began dating in 2018 and wed in October 2019.
Nicole 'Snooki' Polizzi: 3.02-carat
Britney Spears: 3.5-carat
Katy Perry: 4-carat
The pop star's statement flower-shaped ring is as unique as she! Orlando Bloom popped the question to Perry on Valentine's Day 2018. The estimated 4-carat ring is truly glamorous and one-of-a-kind, featuring a pink center diamond surrounded by eight smaller diamonds. ET spoke with jewelry expert Kathryn Money, Vice President of Strategy and Merchandising for Brilliant Earth, who shared that the center gemstone appeared to be a ruby or vivid pink diamond (weighing an estimated 2-2.5 carats), surrounded by a floral halo of eight round diamonds (an estimated 2-2.5 total diamond carat weight) and set in yellow gold. Depending on the quality and specific characteristics of the center gemstone, Money estimated the cost of the ring to be approximately $25,000-$50,000, assuming it's a ruby center gemstone. If it's set with a vivid pink diamond, which is a much rarer gemstone, the ring would cost an estimated $500,000-$2,000,000 or more.
Lea Michele: 4-carat
When the Glee alum said yes to Zandy Reich in April 2018, she accepted this rectangular radiant cut sparkler with a popular diamond halo design, which is set on a pave diamond band. Michele’s stone weighs in at four carats and is classified as a rectangular radiant cut. The piece itself includes a diamond halo and is set on a single, pave diamond band. “A ring [of this caliber] would likely have a value in the range of $100,000 to $150,000," jeweler Greg Kwiat told The Knot, adding, “While it has its roots in antique and vintage jewelry designs, it continues to have a timeless allure. The radiant cut diamond tends to appeal to a woman with a contemporary sense of style. The straight edges and cut corners that are the defining characteristics of the shape speak to a modern design sensibility.” Michele wed the businessman in Napa, California, in March 2019.
Reese Witherspoon: 4-carat
Jennifer Garner: 4.5-carat
Emily Ratajkowski: 5-carats (estimated combined)
The model surprised everyone when she revealed she was hitched! Though she had been wearing a gold band since tying the knot with Sebastian Bear-McClard in a courthouse ceremony in February 2018, Ratajkowski didn't debut her jaw-dropping, self-designer sparkler until July of that year. Made of pear and square cut diamonds, Ratajkowski said she liked the idea of two stones rather than just one and spent a long time looking for inspiration, according to Vogue. In fact, it took 50 sketches to get the bling, which is set on a gold band, just right. "At one point it included a ruby as the second stone, [but] ultimately we loved the idea of the femininity of the pear contrasted with the architecture of the princess," she said.
Christina Aguilera: 5-carat
Katie Holmes: 5-carat
Mila Kunis: 5-carat
Kristin Cavallari: 5.2-carat
NFL quarterback Jay Cutler proposed to the former Laguna Beach star a second time in late 2011 (after breaking off their engagement months before) with a 5.2-carat diamond ring, reportedly worth over $125,000.

Chris Pratt proposed to Schwarzenegger in January 2019, and they wed six months later. They're expecting their first child together in the summer of 2020.
Olivia Wilde: 6-carat
Hailey Bieber: between 6-10 carats
Justin Bieber put a lot of thought and care into picking out a ring for his now-wife. Jack Solow, the ring's designer, told ET in July 2018 that the blonde model got the ring of her dreams, explaining, "The ring is gorgeous. It is what Hailey wanted. She wanted a gorgeous band with diamonds and that is what she got, one row of diamonds around the band and a sprinkle of diamonds in the gallery. The ring complements the center stone.” While Solow would not comment on how much the sparkler cost, he did share that it was between six and 10 carats and other outlets have estimated it to be worth about $500,000. "It was an expensive ring," he adds. "He bought something special for her.”
Jessica Biel: 6-carat
Blake Lively: 7-carat

Cardi B: 8-carat
The “Bodak Yellow” rapper flashed her huge ring after saying “Yes” to Migos’ Offset when he popped the question in front of a crowd of nearly 20,000 during their Power 99 Powerhouse concert in Philadelphia.

The style is glamorous and modern with a touch of timeless vibes. Jewelry expert Kathryn Money, SVP of Merchandising and Retail Expansion of Brilliant Earth, told ET that the ring is estimated to be up to 11.5 carats. "Demi’s showstopping engagement ring features what appears to be an estimated 8-10 carat emerald cut diamond set on a platinum or white gold band," Money said. "The center diamond is framed by beautiful trapezoid-shaped accent diamonds estimated at ¾ carats each, for a total carat weight of the ring of 9.5-11.5 carats."

When the former Yankee popped the question in March 2019, he presented her with a massive diamond ring that’s estimated to be worth over a $1 million, according to jewelry expert Kathryn Money, Vice President of Strategy and Merchandising for jewelry company Brilliant Earth. Money noted that the estimate is dependent on the quality and specific characteristics of the diamond. “J.Lo’s stunning engagement ring from A-Rod appears to feature a 12-15 carat emerald cut diamond in a classic solitaire white gold or platinum setting,” Money told ET. “The elegant simplicity of the ring’s design allows the gorgeous, show-stopping center diamond to be the focal point.”
Previously, Lopez's ex-husband, Marc Anthony, proposed with an 8.5-carat blue diamond ring, reportedly worth $4 million, while her ex-fiancé, Ben Affleck, gave her a 6.1-carat pink Harry Winston diamond.
