10 of the Most Unique Star-Studded Celebrity Engagement Rings

Last updated on March 09, 2023

Although celebrities are fortunate enough to have the means to afford exquisite engagement rings, the following grooms-to-be demonstrated that when it comes to design, it's the concept that makes it beautiful.

Engagement rings are unique when they reflect the wearers' personality and charm. If you're exploring a distinctive design for your soon-to-be fiancée's ring, read ahead and take inspiration from the gentlemen who garnered a yes!


1. Scarlett Johansson and Colin Jost

Platinum? Not today. Scarlett Johansson's striking eleven-carat pear-shaped champagne diamond is set on a dark brown band. The engagement ring is reportedly the work of James de Givenchy, who is not only the nephew of famed fashion designer Hubert de Givenchy––but is also the designer of Taffin, a jewellery brand based in New York.

2. Mary-Kate Olsen and Olivier Sarkozy

An elegant and timeless vintage design, Mary-Kate's four-carat European-cut diamond, encompassed by 16 calibre-cut vivid blue sapphires, is as unique as it is breathtaking. 

During the Art Deco period of the early 20th century, the calibre-cut was a popular gemstone cutting technique that allowed for faceted gemstones to be carefully custom cut to the point that they line up perfectly together. And that they do, sitting in a basket of single-cut white diamonds that alternate with delicate gold tendrils. 

French banker Olivier Sarkozy bought the unique 1953 Cartier piece at a Sotheby's jewellery auction for $81,250.

3. Ariana Grande and Dalton Gomez

The unique history behind Ariana Grande's engagement ring makes it one-of-a-kind, if only for her. The dainty pearl set alongside a nearly six-carat oval-cut diamond is rumoured to have come from her late grandfather's tie pin. The musical pop star once tweeted, "he told her in a dream it'd protect me."




5. Megan Fox and Machine Gun Kelly

The duality of this engagement ring is as unique as the musical composition of Machine Gun Kelly's alternative rock and hip hop. It features his diamond birthstone alongside the emerald birthstone of actress Megan Fox. The pair of pear-shaped stones are set "on two magnetic bands of thorns that draw together as two halves of the same soul forming the obscure heart that is our love," as MGK wrote on Instagram.




6 . Katy Perry and Orlando Bloom

'Cause baby, you're a firework.' 

Like her hit song, Orlando Bloom gifted Katy Perry a firework of an engagement ring when he proposed. The lipstick red ruby sits within a floral halo of diamonds that not only befits their soon-to-be married name but also suits her bright and fun sense of fashion.

7. Halle Berry and Olivier Martinez

Jeweller Robert Mazlo designed the unique emerald ring commissioned by groom-to-be Olivier Martinez for his then-girlfriend, Halle Berry. The brilliantly green emerald flanked on either side by two diamonds is set in a textured gold band. Adding to its rarity is the inscription. Sourced from Columbia is said to include codes and symbols only the wearer can decipher.

8. Bridget Marquardt and Nick Carpenter

When horror-film director Nick Carpenter set out to propose to Bridget Marquardt, he knew that she wanted something unique, and something unique is what she got––a one-of-a-kind pavé diamond-encrusted-spider engagement ring.

9. Jessica Simpson and Eric Johnson

What makes Jessica Simpson’s engagement ring so unique is its five-carat size, not the ruby itself (yes, they have been seen and done before). Rubies of this size are hard to source, prompting a price tag that sings cha-ching! Especially when you add the two-carat pear-shaped diamonds flanked on either side.

Originally designed by Tiffany and Co. and procured from Neil Lane, the unique ruby set within this classic three-stone engagement ring design reflects Jessica's July birthstone.

10. Ashlee Simpson and Evan Ross

Hunger Games actor and son of legendary music icon Diana Ross, Evan Ross, proposed to Ashlee Simpson with a unique Edwardian-style five-carat, marquise-cut diamond and ruby elongated navette-shaped engagement ring in January 2014. Based on a vintage design from Neil Lane's archival collection, it is reminiscent of an Edwardian era often called the "Belle Epoch".
