US Icons: 2016–2020
1. Mariah Carey — 35-Carat Emerald Cut
Proposed to by Australian businessman James Packer in January 2016, Mariah Carey's ring featured an emerald-cut diamond of approximately 35 carats set in platinum, flanked by tapered baguettes. It was widely estimated at around $10 million.
2. Serena Williams — Oval Three-Stone
Alexis Ohanian proposed to Serena Williams in December 2016 with an oval-cut center diamond of roughly 12 carats, framed by two smaller stones — an early sign of the three-stone silhouette's resurgence. The ring is estimated at around $3 million.
3. Priyanka Chopra — Cushion Cut
Nick Jonas proposed in July 2018 with a cushion-cut diamond from Tiffany & Co., estimated at 4 to 5 carats and set in platinum with baguette side stones. Gemology experts placed its value between $200,000 and $300,000, in the G colour, VS1 clarity range.
4. Hailey Bieber — Oval Solitaire
Justin Bieber proposed in 2018 with an oval-shaped solitaire diamond of roughly 8 carats from New York jeweler Solow & Company, estimated around $600,000.
5. Ariana Grande — 3-Carat Oval Diamond & Pearl
Dalton Gomez proposed in December 2020 with an unconventional pairing: a tilted, roughly 3-carat oval diamond set beside a pearl sourced from Grande's grandfather's tie pin — a sentimental, non-traditional take on the custom-designed ring. Published estimates vary widely (3 to 8 carats depending on the source), with value estimated at up to $750,000.

6. Meghan Markle — 4-Carat Cushion Trilogy
Prince Harry proposed in November 2017 with a three-stone yellow-gold ring: a large 4-carat cushion-cut center diamond flanked by two round diamonds sourced from Princess Diana's personal collection — a design choice widely credited with the trilogy ring's renewed popularity.
7. Princess Catherine — 12-Carat Oval Sapphire
In 2010, Princess Catherine's 12-carat oval sapphire, ringed by diamonds and originally worn by Princess Diana, remains one of the most searched engagement rings in the world and continues to make headlines into 2026 — a reminder that great design never really goes out of style.
The New Wave: 2021–2023
8. Kourtney Kardashian — 10-Carat Oval
Travis Barker proposed in October 2021 with a flawless, roughly 10-carat oval diamond designed by Lorraine Schwartz. Estimates place its value between $900,000 and $1 million.
9. Jennifer Lopez — 8.5-Carat Rare Green Diamond
Ben Affleck proposed in April 2022 with an ultra-rare natural green diamond of approximately 8.5 carats, designed by Rahaminov Diamonds. Estimated between $5 million and $10 million — one of the rarest fancy-cut, colored stones ever given as an engagement ring.
10. Megan Fox — Toi et Moi Diamond & Emerald
Machine Gun Kelly proposed in January 2022 with a custom "toi et moi" design co-created with British jeweller Stephen Webster — pairing an oval diamond and oval emerald to represent both partners' birthstones. Value undisclosed.

The Newest Rings: 2024–2025
12. Zendaya — East-West 5-Carat Cushion Cut
Tom Holland proposed in late 2024, with Zendaya debuting the ring at the 2025 Golden Globes. The design, by jeweller Jessica McCormick, features an elongated cushion-cut natural diamond of approximately 5 carats, set horizontally in an east-west orientation on a thin yellow gold band with a Georgian-inspired button-back setting.
13. Taylor Swift — Old Mine Brilliant Cut
Travis Kelce proposed in August 2025 with a ring he co-designed alongside jeweller Kindred Lubeck of Artifex Fine Jewelry. The centerpiece is an antique-inspired Old Mine Brilliant cut diamond, estimated between 7 and 10 carats, in a bezel setting on an 18K yellow gold band with an engraved detail. Expert estimates for the ring's value range widely, from roughly $550,000 up to $1 million or more.
14. Selena Gomez — 6-Carat Marquise Cut
Benny Blanco proposed to Selena Gomez in December 2024 with an estimated 6-carat marquise-cut diamond (published estimates range 4 to 9 carats), set in a north-south orientation on a yellow gold pavé band. Gomez later had the original baguette side stones removed and repurposed into a pair of earrings, replacing them with a cleaner pavé eternity band — turning the piece into a set of three. Value estimated upwards of $225,000.
15. Dua Lipa — 3-Carat Round Diamond
Dua Lipa confirmed her engagement to actor Callum Turner in June 2025. Her ring, custom-made by Turner with input from Lipa's sister and friends, features a round-brilliant-cut diamond estimated between 2 and 3.5 carats, set low in a semi-bezel on a thick (~5mm) 18K yellow gold "cigar band" — a deliberate departure from the delicate solitaire trend. Estimated value ranges from roughly $200,000 to $270,000.
What These Rings Have in Common
What ties this newest wave together is a move away from the identical round-solitaire-in-a-box formula. Elongated cuts, antique references, and bold, unconventional settings have replaced the classic four-prong halo as the ring most likely to make headlines.

Frequently Asked Questions
Which celebrity engagement ring style is most popular right now?
Elongated cushion, marquise, and old mine cuts set in warm yellow gold — as seen on Zendaya, Selena Gomez, and Taylor Swift — are currently the most referenced styles among couples requesting custom designs. At Carat Heritage, it's definitely the most trendy ring design requests we have received in 2026.
Can I get a similar look with a lab-grown diamond?
Yes. Cut and setting style drive most of a ring's visual identity, and IGI-certified lab-grown diamonds can be cut, graded, and set in the same silhouettes seen here — often allowing for a larger center stone within the same budget. Browse by carat size or diamond shape to start.
How accurate are celebrity ring value estimates?
Most figures reported by outlets are expert estimates based on photographs, not confirmed receipts, so actual carat weight and price can vary meaningfully — sometimes by several carats or hundreds of thousands of dollars — from headline numbers.
Designing Your Own
Every ring on this list began the same way: a conversation about what the wearer actually loves, translated into a design that's entirely their own. If one of these silhouettes has caught your eye, our private showroom is where that conversation starts — no pressure, just a piece made around you.
