A ring on a famous finger becomes public property the moment cameras catch it. Fans zoom in, publications speculate on cost, and jewelers weigh in on carat weight from photographs alone. The stones themselves carry stories tied to relationships that play out under constant scrutiny. Some rings outlast the engagements they represent. Others end up at auction or stolen from hotel rooms. What remains consistent is the appetite for knowing exactly what sits on a celebrity’s left hand and what it cost to put it there.
Rings That Defined Eras
Grace Kelly’s 10.48-carat emerald-cut diamond set the standard for old Hollywood glamour. The ring, designed by Cartier with two baguette-cut side stones, belongs to the House of Grimaldi and carries a present-day estimated value of $38.8 million. That figure makes it one of the most expensive engagement rings in recorded history.
Elizabeth Taylor collected remarkable jewelry throughout her life, but the Krupp diamond from Richard Burton remains the most discussed. Burton paid $305,000 for the 33.19-carat Asscher-cut stone in 1968, purchasing it from actress Vera Krupp’s estate. Christie’s sold the ring in 2011 for $8.8 million.
Jackie Kennedy received two notable rings from two husbands. John F. Kennedy gave her a Van Cleef and Arpels piece featuring 2.8-carat diamond and emerald jewels. Aristotle Onassis later presented a 40-carat emerald-cut diamond that she kept in a bank vault. That ring fetched $2.6 million at a 1996 auction and holds an estimated current value near $20 million.
Classic Cuts That Hold Their Value
Diamond shapes carry weight in celebrity proposals. Dua Lipa’s ring features a round-cut diamond on a chunky gold band, a timeless choice that Turner designed with input from her inner circle. Taylor Swift received an old mine cushion stone, while Grace Kelly’s emerald-cut remains among the most valuable at an estimated $38.8 million. Elizabeth Taylor’s Asscher-cut Krupp diamond sold for $8.8 million at Christie’s in 2011. Each cut reflects a particular era and preference, though the round brilliant continues to appear across decades of high-profile engagements.
Modern Proposals and Their Price Tags
Zendaya wore her engagement ring from Tom Holland at the 2025 Golden Globes, six days after TMZ confirmed the engagement on January 6. The east-west cushion diamond weighs 5.02 carats, set in 18-karat white and yellow gold. Estimates place its value above $200,000. Elle reported that the ring continues to influence engagement trends months later.
Taylor Swift and Travis Kelce announced their engagement in August 2025. Kelce worked with Kindred Lubeck on a bezel-set old mine diamond weighing approximately 8 carats. Fortune reported the stone likely cost around $550,000. Fox Business noted that Kelce selected natural diamonds, which form over periods ranging from 1 billion to 3.5 billion years.
Selena Gomez’s marquise diamond from Benny Blanco arrived in December 2024, set on a yellow-gold pavé band. Harper’s Bazaar reported estimates between $200,000 and $1 million. Gomez told press the shape was inspired by lyrics she wrote for her 2015 song “Good for You.” Marquise cuts account for less than 5% of diamonds on the market, according to industry data.
Dua Lipa confirmed her engagement to Callum Turner on June 12, 2025. British Vogue quoted her saying “Yeah, we’re engaged. It’s very exciting.” Turner designed the ring with help from Lipa’s friends and sister. Brides estimated the round brilliant or old European cut diamond on a wide yellow-gold band costs between $65,000 and $125,000.
Eight-Figure Stones
Cristiano Ronaldo gave Georgina Rodríguez an oval diamond estimated between 25 and 30 carats after eight years together. WWD reported expert estimates ranging from $1.5 million to $5 million, while Elle suggested the ring could reach $5 million to $15 million depending on clarity.
Mariah Carey’s engagement to James Packer until that whole thing crashed and burned in 2016 produced a 35-carat emerald-cut diamond ring worth an estimated $10 million, according to The Knot. The engagement ended, and Carey sold the ring two years later for $2 million. Her earlier ring from Nick Cannon featured a 17-carat pink center diamond with 58 smaller pink diamonds and two half-moon diamonds. That piece carried a $2.5 million price tag.
Jay-Z originally purchased Beyoncé’s 18-carat emerald-cut ring, designed by Lorraine Schwartz, for $5 million. Tacori reported its current value exceeds $9 million.
Rings With Complicated Histories
Kim Kardashian’s engagement rings from Kanye West made headlines for reasons beyond their size. The 2013 proposal featured a 15-carat cushion-cut diamond worth approximately $8 million. A second 20-carat ring was among the items stolen when thieves robbed Kardashian at gunpoint in her Paris hotel room in 2016. NPR reported the total jewelry haul was around $10 million. The engagement ring, engraved with “Adidas” after West’s brand deal, was valued at $4 million. ABC News reported that eight defendants were found guilty in May 2025, with two acquitted.
Paris Hilton has received multiple notable rings. Paris Latsis gave her a 24-carat emerald-cut diamond worth approximately $4.7 million in 2005. The engagement lasted a month after the announcement. Hilton auctioned the ring to benefit Hurricane Katrina victims. Her 2021 engagement to Carter Reum brought a 20-carat emerald-cut ring flanked by baguette and trapezoid diamonds, estimated at $2 million.
A Royal Standard
Princess Diana’s engagement ring from Prince Charles cost £28,000 in 1981. The 12-carat oval sapphire surrounded by 14 round diamonds in 18-karat white gold now belongs to Kate Middleton and carries an estimated value between £300,000 and £400,000. The Antique Jewellery Company reported that global sapphire engagement ring sales increased 300% following the original public announcement. Marie Claire noted the ring draws comparable interest nearly 45 years later.
What Stays Constant
Carat weight and cut quality determine value. Provenance adds to resale price. Rings connected to lasting marriages or historical figures command premiums at auction. The stones themselves, aged over geological time periods, outlast the relationships they symbolize. Some sit in vaults. Others circulate through auction houses. A few remain on the hands that first wore them. The numbers attached to each tell part of the story. The rest belongs to whoever wears the ring next.
