A Closer Look at Millie Bobby Brown's Engagement Ring

Millie Bobby Brown got engaged to Jake Bongiovi in April 2023. Let's take a look at her engagement ring. A cushion-cut diamond surrounded by a halo, set on a pavé band. It's rich in sentiment, not just sparkle. 

The Engagement and the Ring's Origins

On April 11, 2023, Millie posted a black-and-white photo with Jake Bongiovi, quoting Taylor Swift's "Lover" in the caption. That was the public's first glance at the engagement ring. But that wasn't when the story behind it began.

According to Millie, the ring is from her mom. In an interview in August 2023, she said her mother had given the ring to Jake for the proposal. It was a piece she always adored. This wasn't something picked off a store shelf. It had meaning from the start.

There's a story about the proposal too. Jake originally planned to propose underwater during a dive. Since the original heirloom ring could be damaged, he used a placeholder. After the swim, the real ring came out. Yes, it was planned down to the detail, but it stayed personal.

Specs: Cut, Carat, Setting, Material

Cut

Most sources pinpoint it as a cushion cut. A few speculate a round cut. But based on expert reviews and close-up photos, a cushion cut is the more accurate pick. This shape has curved sides and rounded corners. It's not a sharp square or a circle either; it's soft around the edges and simple but elegant.

Carat Weight

Estimates put the center diamond at about 3.90 carats. Some earlier reports suggested 3–3.5 carats, likely basing this on older photos or without taking the halo into account. A cushion cut of that size typically measures around 10 by 8 millimeters. It's big but not oversized.

Color and Clarity

Jewelry experts point to an F color, which means nearly colorless. For clarity, reports say it's VS1. That means any flaws are hard to find, even with a magnifier. In other words, clean and bright.

Halo

A cushion-shaped halo surrounds the main stone, making the ring look bigger. It also helps bounce light, which adds more sparkle in photos and in person.

Band

Micro-pavé diamonds are set closely along the band. Pavé bands are popular because they add shine without making the ring bulky. This type of design is detailed but not loud.

Setting

The diamond is held in place with four prongs. This style keeps the stone secure and lets light enter from the sides. Makes the diamond shine without too much metal showing.

Material

Most sources say white gold. A few say platinum. Both are silvery-white metals. White gold is more common. Platinum is denser, more expensive, and less reflective. Since the ring belonged to Millie's mother, white gold seems more likely based on typical heirloom designs.

What It Might Cost

There's no official price tag. But experts have floated numbers.

Some early reports put a $75,000 to $100,000 value on it.

Others, looking at the size and quality, say it could be worth anywhere from $150,000 to $400,000.

Why the difference? A few reasons:

It's a heirloom. You can't price sentiment, but people often try.

Diamond prices vary based on exact clarity and color. Even small jumps can raise prices by tens of thousands.

Halo settings and pavé bands raise the value due to labor and design.

Some think it's custom-made. That can push the price up.

Even if you set aside the family history, a diamond of that size and specification doesn't come cheap.

After the Engagement: Social Media and Appearances

Millie didn't hide the ring. She showed it off in several Instagram videos and interviews. One big moment was a video posted in June 2023 on her Florence by Mills Coffee page. It gave the public the clearest view of the ring.

At New York Comic Con in 2024, Millie returned to the spotlight wearing not one but two rings. Her engagement ring on one hand, and a slim wedding band on the other.

The wedding band is simple, also pavé. Small diamonds, delicate width. It complements the engagement ring instead of stealing the attention.

Fans caught on quickly. Posts with tags like #MillieEngagementRing and #BrownBongiovi spiked after each sighting. As of early 2025, they've added up to more than 2.8 million posts.

Family and Private Wedding

Jake Bongiovi is not just Millie's fiancé. He's the son of Jon Bon Jovi. That drew more media interest, but the couple stayed private.

The actual wedding took place quietly. First in the U.S. in May 2024. No spotlight, no press. Then in October, they had a second event in Tuscany for close friends and family. Details stayed mostly under wraps except for a few glimpses and confirmations from relatives. Jon Bon Jovi confirmed the small ceremony. No dress photos. No tabloid splash.

Their engagement party, however, was more public-facing. Photos showed a large heart-shaped balloon arch and a neon sign reading "Mr. & Mrs. Bongiovi." Millie wore ivory lace. That was in summer 2023, months before the actual wedding.

Public Opinion and Style Influence

Jewelry watchers and stylist reviews have been mostly positive. Designers mentioned the ring as a smart mix of vintage and current trends. The cushion cut is not new, but it's not worn by everyone either. The halo and pavé band lean traditional, but don't look old-fashioned.

This kind of combo has caught on. In 2024 and early 2025, brands reported a boost in interest for engagement rings with cushion cuts and halo settings. Similar designs now appear in custom requests across several bridal-focused jewelers. Some retailers say they've seen as much as a 40 percent uptick in interest for similar styles.

Fans noted how the ring matches Millie's public image. Polished but not loud. Young but with a nod to things with meaning.

Some online users compared it to Princess Diana's sapphire ring. Not in color or stone, but because both rings stand out and have personal connections. Others mentioned how the ring suits Millie's Stranger Things association. Again, not the exact design, but the mood.

Celebrity rings often set style waves, but this ring isn't about status. That's what people seemed to like. It wasn't showy. It was hers — from her mother, shaped by her partner.

The Bottom Line

When you take apart Millie Bobby Brown's engagement ring, here's what you're left with:

A cushion cut diamond, around 3.90 carats.

F color, VS1 clarity. High quality, but not exaggerated.

Halo and pavé band, most likely in white gold.

Value estimate ranges from $75,000 to $400,000.

A family heirloom passed from mother to daughter.

Redesigned with input from Jake Bongiovi.

Seen by the public in social media posts, panel appearances, and interviews.

Followed by a quiet wedding, minimal publicity.

Sparked trends in ring design due to its sentimental and classic mix.

The ring tells a story, not through speculation but through details anyone can see. No giant surprises. No gimmicks. Just a solid design tied to people close to her.

And isn't that what a good piece of jewelry should do? Match your life, not someone else's ad campaign.
