Every week I speak with couples who have done their research, they want a lab-grown diamond, and then hit a wall when it comes to the ring itself. Not because the options aren't beautiful, but because there are too many of them with no clear frame of reference.
So, this is my attempt to give you one.
I've ranked the seven most popular engagement ring styles using real sales data from BriteCo's 2026 Jewelry, Diamond & Watch Price Index, which tracks thousands of engagement ring appraisals from 2019 to mid-2026 globally. Then I've layered in what I see at Futurae: which styles come up in every consultation, which ones people fall in love with in person that they hadn't considered online, and which ones suit different ways of wearing jewellery.
This isn't a trend report that you see on Instagram or TikTok. It's a ranked guide to help you find your style faster.
First, Shape and Style Are Two Different Decisions
Before we get into the ranking, it helps to separate two choices that often get blurred together.
Diamond shape is the outline of your centre stone: round, oval, emerald, pear, marquise, cushion or radiant.
Ring style is the design around that stone: a solitaire, a halo, a three-stone ring and so on.
You can combine them however you like. An oval might sit in a simple solitaire, above a pavé band, or between two side stones. Lab-grown diamonds share the same chemical composition, crystal structure and physical properties as mined diamonds, so every style in this guide is open to you - and to your imagination.
#1 The Solitaire (29% of Engagement Rings)
The solitaire is the most popular engagement ring style, and it has held that position for years. Not because it's the safe choice, but because it's the most classic of styles.
One stone. One band. Nothing competing for attention.
Solitaires made up 30% of engagement rings in 2024, 29% in 2025 and 29% again in the first half of 2026. That kind of stability tells you this isn't a trend. It's a permanent preference, and one I never walk past as a recommendation for my customers as a starting point.
Why lab-grown diamonds made the solitaire better
The solitaire is where the value of a lab-grown diamond is most visible. When the whole ring is built around a single stone, carat weight and quality become everything. The typical lab-grown centre stone has more than doubled in size since 2019, from around 1.1 carats to 2.25 carats. A solitaire makes every fraction of that count.
At Futurae, the solitaire is consistently the starting point for clients who know their aesthetic. It's also where I see the biggest shift from what someone thought they wanted to what they actually choose: they come in thinking 1.5 carats, they leave with 2.2.
Who suits a Solitaire?
- Those who prefer clean, architectural jewellery that won't date
- Wearers who stack rings and want a simple, strong base piece
- Anyone who wants the diamond to be the entire story
- Clients who value longevity over novelty
On shape: Round brilliant is the classic pairing, but oval has surged to near-equal popularity. At Futurae, oval solitaires now outsell round in studio appointments.
My advice: Try more than one shape before deciding. The diamond you love in a photograph can feel quite different on your hand.

#2 The Classic Band (20% of Engagement Rings)
The "classic band" is the category that sounds generic but looks anything but. In practice, it's a centre stone paired with a refined, decorated band: small accent diamonds, tapered baguettes, or subtle channel-set stones that add detail without overwhelming the design.
It jumped from 16% of engagement rings in 2024 to almost 20% in 2025, and has held there into 2026. That's the steepest growth of any style in this ranking.
Why it's growing
The classic band satisfies two things at once: visual richness and wearability. It reads as polished and considered rather than ornate, which suits the broader shift toward jewellery that works in every context, not just on occasions.
I think it's also a response to the halo's peak and retreat. Buyers who wanted more than a plain solitaire but felt halos had become too familiar landed here. It's the middle ground that doesn't feel like a compromise.
Lab-grown diamonds make this style more accessible than it's ever been. Accent stones that would have added significantly to the cost of a mined diamond ring are far more attainable, which means more intricate band designs without a disproportionate price jump.
Who it suits
- Those who want detail in the craftsmanship, not the spectacle
- Wearers pairing their engagement ring with a diamond wedding band (this stacks beautifully)
- Anyone drawn to Art Deco or vintage-influenced design
- Clients who want more than a solitaire but find halos too decorative
The emerald cut pairs particularly well here. Its geometric, step-cut facets complement structured bands in a way that round brilliants don't.
My recommendation from our signature collection: the Dea emerald cut ring with the Estelle baguette band.
#3 The Three Stone or Trilogy Ring (11% of Engagement Rings)
Three stone rings carry one of the most enduring narratives in jewellery: past, present and future. That symbolism has kept this style near the top for decades, and the data says it's gaining ground, not losing it.
Three stone rings rose from 10% of engagement rings in 2024 to 11% in the first half of 2026, overtaking the halo for third place. Alongside the classic band, it's the only style in the top six that is growing.
The design logic
The centre stone is flanked by two side stones, which can match the centre shape or contrast it. The side stones frame the centre diamond and make it read larger, which is part of the appeal. With a lab-grown centre stone, you can choose a genuinely larger diamond and still have budget for meaningful side stones.
Pairings I love:
| Centre stone | Side stone options |
|---|---|
| Oval | Tapered pears or smaller ovals |
| Emerald cut | Half-moons or tapered baguettes |
| Round brilliant | Tapered baguettes or smaller rounds |
| Pear | Trillions or tapered rounds |
Who it suits
- Those drawn to symbolic, story-driven jewellery
- Wearers who want maximum visual presence without a halo
- Anyone who appreciates design complexity with clear structure
In the studio, I'm often seeing three stone rings chosen for second marriages and commitment rings, where that past, present and future story carries real weight.
My advice: Look at the three stones as one composition. Their relative sizes, colour and spacing should work together.
Our recent bespoke Trilogy Engagement Ring was a piece we adored making for a lovely couple in Newcastle. It was a reminder of how personal this style becomes when every stone is chosen with intention.
#4 The Halo (10% of Engagement Rings)
The halo has had a fall from its peak, but there's a twist. In 2024 it accounted for 13% of engagement rings; by 2026 that has settled to under 10%, and it has slipped from third place to fourth. This isn't a collapse of a gorgeous design, it's a recalibration. Nothing makes a centre diamond look larger and sparklier.
A halo encircles the centre stone with smaller accent diamonds, creating a border of light that visually extends the stone's diameter. A 1.5 carat stone in a halo reads like a much larger stone to the eye, so it's still well worth considering.
The hidden halo changes everything
What's interesting is where the halo went, not that it declined. The traditional raised halo is giving way to the hidden halo, where the accent diamonds sit beneath the centre stone rather than around it. From above, it reads as a clean solitaire. From the side, you see the halo.
This is the version I'm seeing most in studio appointments now. Buyers who love the sparkle of a halo but want a cleaner profile from above get both. For me, the appeal is in that quieter detail: something you notice as the ring moves.
Who it suits
- Those who want the largest possible visual presence
- Wearers with petite hands, where a halo adds scale proportionately
- Anyone drawn to vintage or romantic aesthetics
- Clients working with a more modest centre carat stone who want maximum impact
My advice: Look at the ring from every angle. With a hidden halo in particular, check the overall height and how a wedding band will sit beside it.
I'm in love with our Paloma oval halo and Emilia round halo, both in 18k gold. A hidden halo can be added to almost any of our designs as a bespoke detail.
#5 The Side Stone Ring (9% of Engagement Rings)
Side stone rings are the close cousin of the three stone, but with a different visual logic. Rather than three distinct stones of comparable size, a side stone setting features a prominent centre diamond with smaller accent stones that taper along the band. The effect is elongated and architectural rather than symmetrically bold.
This style holds 9% of engagement rings in 2026, and it works especially well with elongated centre stones. A pear or oval diamond in a side stone setting creates a continuous line from the stone down the band, making both the stone and the finger appear longer.
The pavé side stone variation
Many side stone rings use pavé-set accent diamonds along the band, adding continuous sparkle rather than a defined cluster. This variation sits between two categories and is one of the most requested configurations in Futurae studio appointments.
If you're drawn to an oval or pear centre stone and want a ring that feels cohesive rather than composed of separate elements, a pavé side stone band is worth considering. It frames the centre stone without competing with it.
Who it suits
- Those who want a ring that feels fluid and continuous rather than structured into distinct sections
- Anyone who wants to lengthen the look of their hand
- Lovers of the oval or pear cut who want a setting that enhances the stone's elongation
- Clients who prefer sparkle distributed across the whole ring rather than concentrated at the centre
The Celeste oval pavé ring captures this design sensibility precisely.
#6 The Pavé Ring (5% of Engagement Rings)
Pavé takes its name from the French word for paved, which describes exactly what it achieves: a band set so densely with small diamonds that the metal beneath is barely visible. The result is a ring that appears to be made entirely of light.
It accounts for 5% of engagement rings in 2026. A niche choice, but a devoted one. Buyers who choose pavé tend to know exactly what they want: maximum sparkle, every single day.
Full pavé versus split shank
Full pavé band: Small diamonds cover the band surface. The centre stone sits within an unbroken field of brilliance.
Split shank pavé: The band divides into two strands as it approaches the centre stone, each set with pavé diamonds. This creates a more dramatic frame and a distinctive silhouette from every angle.
Who it suits
- Those who love maximum sparkle and are happy to give their ring a little extra care
- Wearers who want the ring itself to be the statement, with a more modest centre stone
- Anyone with an affinity for vintage Hollywood or old-world glamour
- Clients who want a ring that is as striking from the side as it is face-up
My advice: Think about how you'll live in it. The small stones can loosen with daily wear, so an annual professional inspection is worth building into your routine, and it's best to take the ring off for anything that exposes it to knocks. A fully diamond-set band can also make future resizing more complicated.
#7 The Statement Shape: Pear, Marquise and the Unconventional Choice
The seventh category isn't a single setting style. It's a design philosophy: choosing an unconventional diamond shape as the primary statement, paired with a minimal or custom setting that gets out of the way.
Pear, marquise, radiant and cushion cuts all sit here, and they're climbing quickly. Sales data from Queensmith, a leading London jeweller, shows pear cut diamonds grew from 3.6% to 6% of their engagement rings between 2024 and 2025. Marquise grew from 1.8% to 3%, and radiant from 2.25% to 4%. These are significant movements in a short window.
Why fancy shapes are having a moment
Round brilliant diamonds are optimised for maximum light return. They are objectively brilliant. But that uniformity is also what makes them feel familiar. Fancy shapes carry a distinctiveness that round stones can't replicate.
The pear cut in particular has become a signature of the design-led buyer. Its teardrop silhouette elongates the finger, its pointed tip creates a directional energy that round cuts lack, and it sits beautifully in both classic solitaire and tilted settings. At Futurae, it's consistently the shape that surprises people most in person: they come in curious, they leave committed.
Lab-grown diamonds are accelerating this shift. When you can access more carat weight per dollar, you're less likely to default to the "safe" choice. You choose the shape you actually love.
Who it suits
- Those who want a ring that is immediately recognisable as theirs
- Wearers who follow design closely and want jewellery that reflects that
- Anyone open to a bespoke setting built around an unconventional stone
- Clients who have admired an editorial or celebrity ring and traced it back to a fancy shape
Our Pirum pear solitaire and Pirum tilted pear are two of the most distinctive pieces in the Futurae signature collection, designed to let the shape lead everything.
How to Find Your Style
Popularity is a useful starting point, not a decision. The right engagement ring style is the one that fits your story: how you wear jewellery, how you live in it, and what you want it to say about you, your relationship and future together.
A few questions worth sitting with before you decide:
Do you wear your jewellery every day? Solitaires and classic bands wear beautifully daily. Pavé and halo settings need more care over time.
Do you gravitate toward clean lines or intricate detail? Solitaires and side stone rings reward minimalism. Three stone and halo settings reward complexity.
What matters more: the stone or the setting? If the diamond is the story, a solitaire lets it speak. If you want the ring as a whole to make the statement, a halo or pavé delivers that.
Are you pairing it with a wedding band? Try them together where you can. Solitaires and classic bands pair with almost anything. Halos can be more restrictive.
One thing I always tell my clients: lab-grown diamonds change what's possible. Because you can access significantly more carat weight and quality for the same investment, the style you choose doesn't need to be constrained by what you can afford in a particular setting. The design you actually want is more within reach than you might expect.
Here are some answers to questions I am asked all the time.
What is the most popular engagement ring style this year?
The solitaire, at around 29% of engagement rings, followed by the classic band at around 20% and the three stone ring at around 11%.
Can lab-grown diamonds be used in any engagement ring style?
Yes. Lab-grown diamonds work across solitaire, classic band, three stone, halo, hidden halo, side stone, pavé and bespoke designs. The setting should always be engineered for your diamond's shape and dimensions.
What is the difference between a halo and a hidden halo?
A traditional halo surrounds the centre diamond with smaller stones you can see from above. A hidden halo sits beneath the centre stone and is most noticeable from the side.
Is a three stone ring the same as a trilogy ring?
Yes. Both describe a ring with three principal stones. "Trilogy" tends to emphasise the symbolism of past, present and future.
Which engagement ring style is best for everyday wear?
Solitaires and classic bands are the easiest to live with day to day. A bezel setting offers extra protection around a diamond's edges, while fine pavé and higher settings need more care.
Can I customise a Futurae engagement ring?
Yes. We can adjust diamond shape, carat, proportions, metal and setting details on any piece in our signature collection, or design something entirely bespoke with you.
