Few celebrity engagement rings get argued about this much. The Megan Fox ring is a two-stone toi et moi design, and almost nothing about it follows the usual script. An emerald sits beside a diamond, and the bands are shaped like thorns. Below is what the piece is made of, what it reportedly cost, and how the style works on a normal budget.
Megan Fox’s engagement ring is a bespoke toi et moi design by British jeweler Stephen Webster, created with Machine Gun Kelly. It sets a pear-cut untreated Colombian emerald, her birthstone, beside a pear-cut D-color diamond, his. Those two halves separate into individual rings, and magnets hold them together on the finger.
Key takeaways
- Stephen Webster designed it. Machine Gun Kelly supplied the concept.
- Setting style is toi et moi: a pear-cut emerald next to a pear-cut diamond, with pave along the bands.
- The shanks are formed as thorns, and the couple publicly tied that to the phrase “love is pain”.
- Reported cost estimates start near $300,000 and run past $400,000. None are official.
- A toi et moi inspired ring runs from about $110 in moissanite to $25,000 and up in fine natural stones.
What the Megan Fox ring actually looks like

Picture two pear-shaped stones lying head to tail. One is green. One is white. Together they make a shape people keep calling an offset heart, though it reads more like a teardrop meeting its own mirror image.
That band is not a single loop. It splits, curves, and rejoins, with small pave diamonds running along the shanks in white gold.
Emerald and diamond, up close
The green stone is a Colombian emerald. Machine Gun Kelly has said it was untreated and carved into a teardrop straight out of the mine. Emerald is Fox’s birthstone. Beside it sits an antique cut, D color diamond, which is his. Birthstone pairing is the entire idea.
Carat weights are less settled. No official numbers have been released, and published estimates disagree sharply. A jewelry designer quoted by the business press put both stones near 6 carats each. A UK jeweler’s analysis landed closer to 3 carats for the diamond and 4 for the emerald. Colored stones come up constantly in our jewelry coverage, and emerald is the one readers ask about most.
Thorn bands and magnets
This is the detail that made the ring famous. Both shanks are formed as thorns, and they pull toward each other with magnets so the stones sit flush. Machine Gun Kelly explained it plainly. The ring comes apart into two rings; a magnet holds it in place, and the thorns mean it hurts to take off.
Webster has described the stones as attracted to each other, settling together perfectly once they meet. He called that detail modern and quite extraordinary.
Who made it, and what it reportedly cost
Stephen Webster is a British jeweler with a long celebrity client list, and this piece belongs to his bespoke bridal line. He has said the brief arrived from Machine Gun Kelly in an almost lyrical form. White gold in the piece was responsibly sourced.
Cost is where reporting gets loose. One jewelry designer quoted in early coverage estimated around $300,000. Other outlets have run figures above $400,000. Neither Fox nor Webster has confirmed a number, so treat all of it as reported, not established.
When and where the proposal happened
Machine Gun Kelly proposed on January 11, 2022, in Puerto Rico. It happened under a banyan tree at a resort the pair had visited together before. Fox shared the news herself.
Where the two stand now
They split in late 2024. Since then, outlets have referred to Machine Gun Kelly as her ex-fiancé, and reporting through 2026 describes the two as co-parenting rather than romantically involved. Occasional social media exchanges have set off reunion rumors, and sources close to both have denied them each time.
What happened to the ring itself has never been publicly confirmed.
Toi et moi: a style much older than the trend
Toi et moi is French for “you and me”. That setting puts two stones side by side on one band, one for each person in the couple. It is not a modern invention at all.
Napoleon gave Josephine a toi et moi ring in 1796, pairing a pear-shaped sapphire with a diamond. Victorian couples adopted it. Art Deco designers sharpened the geometry and started mixing diamonds with onyx and emerald. In 1953, John F. Kennedy gave Jacqueline Bouvier a Van Cleef and Arpels version holding a 2.88 carat diamond and a 2.84 carat emerald.
The current revival owes a lot to celebrity fashion. Ariana Grande’s oval diamond and pearl ring landed in 2020, Fox’s followed in 2022, and search interest climbed after each. There is a practical reason too. Two medium stones read larger than one, and the format lets you keep a colored stone without giving up the diamond.
What a toi et moi inspired ring costs
You are not buying that ring. You can absolutely buy the shape. Prices break into clear tiers, and the jumps between them come down to whether the stones were grown, mined, or inherited.
| Budget | Typical stones | Metal | What you get |
| $110 to $400 | Moissanite pair, roughly 2 to 3 carats total | Sterling silver or gold vermeil | Promise ring weight. Plating wears within a year or two of daily use. |
| $1,800 to $3,500 | Lab-grown diamond pair, about 2 carats plus 1.5 carats | 14k gold | A real engagement ring build with a plain or pave band. |
| $3,500 to $8,000 | Lab-grown diamond with lab or commercial-grade emerald | 14k or 18k gold | Bigger stones, custom shank shaping, better finishing. |
| $8,000 to $25,000 | Natural emerald plus a certified natural diamond | Platinum or 18k gold | Colombian material, graded stones, jeweler set by hand. |
| $25,000 and up | Fine or antique stones, signed or fully bespoke | Platinum | Designer names, auction grade color, one of one pieces. |
Two notes on those tiers. Lab grown diamonds have pulled the middle band down hard, and a 2 carat plus 1.5 carat pair now starts near $1,840 at some direct sellers. Natural emerald is the variable, because strong Colombian color with few visible inclusions can cost more per carat than the diamond beside it.
Styling a two-stone ring
Green reads cool against white metals and warm against yellow gold. Pick a side and commit.
A ring this wide crowds a stack, so wear it alone or with one thin band. It also sets the color story for your outfit. Emerald sings against plain black or ivory evening dresses, not busy prints.
Living with a setting like this one

An unusual ring brings unusual maintenance. Here is what to plan for.
- Snagging. Raised thorn detail and split shanks catch on knits, hair, and coat pockets. Sweater season is the real test.
- Comfort. Interior texture presses into the finger all day. Ask for a smoothed inner surface unless you want the drama.
- Resizing. An asymmetric two stone ring costs more to size than a plain solitaire, since the stones have to stay aligned after the shank is cut. Some split band designs barely size at all.
- Cleaning. Emerald sits around 7.5 to 8 on the Mohs scale and is usually oiled. Skip the ultrasonic cleaner. Warm water, mild soap, soft brush.
- Prong checks. Two stones in one head create uneven stress. Have the prongs looked at once a year.
Insuring a colored stone ring
Get an appraisal before the ring leaves the store. Ask the appraiser to document the emerald’s origin and any oiling or clarity enhancement, because that changes replacement value later. Most jewelry policies run 1% to 2% of appraised value each year, so a $10,000 ring costs roughly $100 to $200 annually to cover. Re-appraise every two or three years.
Ask one more question before signing. Does the policy replace the exact stone, or something similar? On a custom two stone piece, that gap is the whole argument.
Ready to shop the look

Start with the stone rather than the setting. Decide between mined emerald, lab-grown emerald, and green sapphire first, then let a jeweler build the toi et moi around your pick. Bring a reference photo to that appointment. Ask to see the shank profile in wax or resin before anything gets cast.
Conclusion
The Megan Fox ring became famous because it was never meant to be a traditional engagement ring. Its emerald and diamond pairing, thorn-shaped bands, and magnetic design turned a personal love story into a piece of jewelry history. While the reported $300,000-plus price tag places the original far outside most budgets, the appeal of the toi et moi style comes from the idea behind it: two stones representing two people, brought together in one design.
For buyers today, the lesson is not to copy every detail of the celebrity piece. The lasting value is in the concept. A well-made toi et moi ring can combine personal meaning, color, and craftsmanship at many price points, from affordable moissanite versions to custom natural gemstone creations. The Megan Fox ring may be one of the most talked-about celebrity rings of recent years, but its real influence comes from proving that engagement jewelry does not have to follow a single formula.
