Why Megan Fox’s Engagement Ring Was Designed to Cause Pain When Removed

Megan Fox and Machine Gun Kelly may no longer be together, but the actress’s unique engagement ring continues to captivate pop culture fans and jewelry enthusiasts alike.

Fox and the pop-punk singer were together from early 2020 to December 2024, at which time they reportedly split, per People. The former couple welcomed their first child together, a daughter, on March 27, 2025.

MGK, whose real name Colson Baker, proposed to Fox in January 2022. The Transformers actress wrote a lengthy caption to a now-deleted Instagram post detailing the moment, writing that “having walked through hell together, and having laughed more than I ever imagined possible, [MGK] asked me to marry him." 

“And just as in every lifetime before this one, and as in every lifetime that will follow it, I said yes.…and then we drank each other's blood," she added.

If that vampiric ritual wasn’t gothic enough, the ring features a design element symbolizing that true love’s flower has its thorns—literally. “The bands are actually thorns. So if she tries to take it off, it hurts,” MGK told Vogue in 2022, adding, “Love is pain!”

While they’re no longer a couple, the pair are “on the same page when it comes to co-parenting,” a source shared with People in March 2025. Below, revisit Fox’s one-of-a-kind engagement ring from her whirlwind romance with former fiancé Machine Gun Kelly.

It’s actually two separate rings drawn together via magnets.

While it looks like one ring, Fox’s engagement ring is actually two bands magnetized together—a symbol of their twin flame connection. Each band has its own stone, and when stacked, they form a classic Toi et Moi (‘you and me’) style.

"By the use of magnets buried within the gold, [the rings] are attracted to each other and sit together perfectly on the finger," the designer of the bespoke ring, Stephen Webster, told People shortly after the proposal. "[It's] a detail that is both modern and quite extraordinary."

MGK described the unique design choice poetically in the caption of his Instagram post about the engagement: “i know tradition is one ring, but i designed it with Stephen Webster to be two: the emerald (her birth stone) and the diamond (my birth stone) 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.”

It features pear-cut stones on interlocking white gold pavé bands.

In their Instagram posts about the proposal, Fox and MGK showed off the ring’s two pear-cut stones: a white diamond and a green emerald. The diamond is MGK’s birthstone, while the emerald is hers.

While neither the then-couple nor the ring’s designer revealed the stones’ carats, MGK told Vogue a little more about the dazzling sparkler during Milan Men’s Fashion Week in 2022. “It’s a thoroughbred Colombian emerald, with no treatment,” the “Cliché” singer revealed. “It was just carved into the teardrop, straight out of the mine. And the diamond was directly from Stephen [Webster].”

Renowned English jeweler Webster shared more insight with People. "The diamond is a D-color antique cut and the emerald is an extraordinary, completely untreated Colombian gem," he said, adding that the colorless diamond pavé bands “perfectly” match the ring’s stones. 

The bands are 18 karat white gold, with the aforementioned magnets “buried within the gold” to draw the two rings together into one, per Webster.

It’s worth an estimated $300,000.

In January 2022, multiple experts told People that Fox’s engagement ring is worth at least six figures—and potentially up to half a million dollars. 

Sahar Manley, owner of jewelry label Camilla Seretti, suggested that since the ring’s diamond and emerald look to be 7 carats each, the ring could be “valued at nearly $500,000.”

Jewelry designer Mark Broumand offered a more conservative estimate. "This Toi et Moi [you and me] style has a very unique look. The gorgeous white diamond and green emerald really compliment each other,” he said. “They indeed look to be top quality, putting the ring cost around $300,000."

MGK chose thorn bands so it "hurts" to take the ring off.

Helping the engagement ring go viral was the revelation that its bands are “actually thorns.” Their sharp edges were shaped so the ring would hurt when Fox took it off, as MGK revealed to Vogue in 2022.

The genre-blurring musician popped the question to Fox under a banyan tree in Puerto Rico—the same one they “fell in love under,” according to his Instagram post about the engagement. After she said yes to the proposal, the former couple drank a small amount of each other’s blood.

"It’s just a few drops,” the Jennifer’s Body actress clarified in a video interview with British Glamour a few months after the engagement. “But yes, we do consume each other’s blood on occasion, for ritual purposes only. It is used for a reason and it is controlled, where it’s like, ‘Let’s shed a few drops of blood and each drink it,’” she added.
