Megan Fox’s engagement ring from Machine Gun Kelly stood out for its unusual combination of a diamond, an emerald, and two interlocking bands. Designed with British jeweler Stephen Webster, the custom piece brought together personal symbolism and an unconventional, edgy aesthetic.
The Megan Fox engagement ring was more than a traditional diamond solitaire. Its two pear-shaped gemstones represented the couple’s birthstones, while magnetic bands and thorn-inspired details gave the design a distinctive identity. Although its reported value attracted considerable attention, the exact purchase price and independently verified gemstone weights have not been publicly established.
What Is Special About Megan Fox’s Engagement Ring?
Megan Fox’s ring is notable for its two-stone design, combining a diamond with a green emerald. Rather than placing both gemstones on a conventional single band, the design consists of two interlocking ring components that come together to create one distinctive piece.

According to coverage by Vogue, Machine Gun Kelly worked with jeweler Stephen Webster to develop a ring that reflected their relationship and personal symbolism.
The most recognizable design features include:
- Two contrasting gemstones: A white diamond and a green emerald create a striking visual contrast.
- Pear-shaped stones: Both gemstones have an elongated, teardrop-like outline.
- Magnetic construction: The two bands use embedded magnets to hold them together when worn as one.
- Thorn-inspired details: The bands feature a sharp, alternative design that complements the couple’s aesthetic.
- Personal symbolism: Each gemstone represents one partner’s birthstone.
These details make the ring an interesting example of how engagement jewelry can move beyond a conventional solitaire while retaining the significance of a diamond.
Who Designed Megan Fox’s Engagement Ring?
British jewelry designer Stephen Webster created the ring in collaboration with Machine Gun Kelly, whose real name is Colson Baker.
The couple announced their engagement in January 2022. Both shared the news on social media, and Baker explained the idea behind the unusual two-piece design.
In an interview with Vogue, Webster described how Baker provided extensive creative direction and personal inspiration. Webster then translated those ideas into two rings designed to connect through magnets.
The result was a bespoke design rather than an ordinary off-the-shelf engagement ring.
The collaboration also demonstrates an alternative approach to engagement jewelry: instead of selecting a standard setting, couples can develop a custom design around meaningful gemstones, distinctive materials, and personal symbolism.
Diamond and Emerald: The Meaning Behind the Two Stones
One of the most memorable aspects of the Megan Fox engagement ring is the meaning attached to its center stones.

The diamond
The diamond represents Machine Gun Kelly’s birthstone. It provides a bright contrast against the emerald and helps balance the two-stone design.
In reporting about the ring, jeweler Stephen Webster described the diamond as an antique-cut, D-color natural diamond. These details were reported in connection with the designer’s own description of the piece rather than independently verified through a publicly available grading report.
The emerald
The emerald represents Megan Fox’s birthstone. Baker described it as an untreated Colombian emerald, and the designer’s description also identified the gemstone as Colombian and untreated.
Emeralds are valued for their rich green color, which can look particularly striking beside a colorless diamond. However, emeralds generally require more careful handling than diamonds because they are more vulnerable to damage from impacts and certain types of wear.
The combination illustrates how a colored gemstone can give an engagement ring a more personal appearance without eliminating the diamond’s familiar brilliance.
How Much Is Megan Fox’s Engagement Ring Worth?
Megan Fox’s engagement ring has been associated with a reported value of $300,000 to $400,000, according to an estimate published by Seventeen from Kathryn Money, then senior vice president of merchandising and retail at Brilliant Earth.

That figure should be treated as an expert estimate, not a confirmed purchase price, insurance valuation, or current resale value.
Other media reports have published different figures, reflecting the difficulty of valuing a custom ring from photographs and publicly available design information.
Several factors could influence the value of a piece like this:
- Diamond characteristics: Carat weight, color, clarity, cut, and other quality factors affect diamond pricing.
- Emerald quality: Color, transparency, treatment status, origin documentation, and other characteristics can influence an emerald’s value.
- Custom craftsmanship: The bespoke construction and designer’s work may contribute to the piece’s overall cost.
- Metal and accent stones: The materials used in the bands and any additional diamonds can affect the final price.
Without an official price statement, complete gemological documentation, and an authenticated appraisal, no single reported figure should be treated as definitive.
How Many Carats Are Megan Fox’s Diamond and Emerald?
The exact carat weights have not been established by a publicly available grading report in the sources reviewed.
In its coverage of the ring, Seventeen reported Kathryn Money’s estimate of approximately 4–5 carats for the diamond and 4–4.5 carats for the emerald.
Other publications have cited different estimates. These differences are a reminder that a gemstone’s apparent size in a photograph is not enough to determine its exact weight.
Carat measures a gemstone’s weight, not its visible dimensions alone. Two stones with the same carat weight can look different in size depending on their proportions, depth, and shape.
For that reason, the figures above should be understood as attributed estimates rather than confirmed specifications.
What Makes the Ring’s Magnetic Thorn-Band Design Unusual?

The ring’s construction is one of its most distinctive features.
Instead of using a single conventional band, the design brings together two interlocking ring components. Embedded magnets help hold the pieces together when worn as one ring.
The bands also feature thorn-inspired details, reinforcing the ring’s unconventional aesthetic.
This construction gives the piece a sculptural appearance and makes it particularly different from traditional engagement rings, which typically use one band to support a central gemstone.
However, the design is not necessarily practical for every wearer. Thorn-like details can catch on clothing, and pointed or protruding elements may be less comfortable for people who work with their hands. Anyone considering a similar design should assess the setting’s comfort, snag resistance, and everyday durability before buying.
How to Recreate the Megan Fox-Inspired Engagement Ring Style
You do not need the exact designer or a six-figure budget to explore the broader look of Megan Fox’s engagement ring. The most transferable ideas are its two-stone arrangement, contrasting colors, pear-shaped silhouettes, and alternative design details.
1. Explore a Toi et Moi ring
A Toi et Moi ring features two prominent gemstones positioned together, often symbolizing two people or complementary elements.
Browse Toi et Moi engagement rings for designs that explore this two-stone concept.
2. Consider a pear-shaped diamond
Pear-shaped gemstones have a rounded end that tapers to a point, creating a teardrop-like outline. They can give a ring an elongated appearance and work well in both modern and vintage-inspired designs.
Explore pear-shaped lab-grown diamond engagement rings if you prefer the silhouette of one of the ring’s center stones.
3. Look at two-stone settings
If the paired-gemstone arrangement is what appeals to you most, compare different two-stone designs. Some combine two diamonds, while others use contrasting gemstones or different shapes.
The two-stone lab-grown diamond engagement ring collection is another place to explore the broader design concept.
4. Choose an alternative design
Megan Fox’s ring has a bold, unconventional look. If you prefer jewelry that moves away from traditional solitaire styles, consider designs with sculptural bands, distinctive settings, or darker and more dramatic details.
Browse alternative engagement rings for other nontraditional design directions.
5. Prioritize comfort and durability
A ring can look striking while still being comfortable enough for everyday wear. Before choosing a similar design, consider how securely the gemstones are held, whether pointed details catch on fabric, and whether the setting is practical for your daily activities.
If you choose an emerald, ask about its treatment history and care requirements. Emeralds can be more susceptible to damage than diamonds, so a protective setting and appropriate maintenance may be especially important.
