Something has shifted in the way people choose an engagement ring. For most of the last decade there was a default look, a round diamond in a pavé halo on a slim white metal band, and the main question was how many carats. That question is quietly being replaced by a different one. People are asking what the ring says about them, not what it signals to everyone else.
You can see it in the styles gaining ground. Two-stone settings, stones turned sideways, warmer metals, shapes that used to be considered unusual. None of this is trend for its own sake. It is the visible result of three quieter changes underneath. Lab-grown diamonds have become the natural starting point, which frees up budget to spend on cut and design rather than carat weight. Couples increasingly want a piece that suits their actual daily life. And there is a genuine appetite for a ring that could only belong to one person.
Here are the styles leading that shift, what each one is really about, and the honest version of how it wears once it leaves the showroom.
Toi et moi, two stones and one story
If one style defines the current moment, it is the toi et moi. The name is French for "you and me", and the design sets two stones side by side on a single band rather than building the ring around one central diamond. The two stones stand for two people, which is a large part of why it resonates now. It reads as a portrait of a relationship rather than a single showpiece.
The style is far from new. Napoleon designed a toi et moi for Josephine in 1796, a yellow gold band holding a pear-shaped sapphire and a pear-shaped diamond. That romantic history is part of the appeal, because it means the design has roots rather than being a passing fashion. A run of high-profile engagements has kept it in view, and UK search interest has climbed sharply over the past year.
Where it gets interesting is the pairing. Contrasting shapes tend to look more deliberate than two matching stones, so oval next to pear, or emerald next to round, are combinations we set often. Many couples pair a diamond with a coloured gemstone, a sapphire or an emerald, which pushes the personal angle further and nods back to that original Napoleon ring.
A word of honesty, since this is the style most likely to go wrong. Balance is everything. A poorly proportioned two-stone ring can look busy or slightly awkward, and the effect is hard to undo once it is made. Two things are worth settling at the design stage. First, how the stones relate in size and angle, because that is what separates a considered piece from one that simply follows a trend. Second, how the ring will sit against a future wedding band. Some toi et moi designs leave room to stack a band alongside, others need a shaped or fitted band to sit cleanly. Planning that early saves disappointment later. Bypass and split-shank versions are also more involved to resize than a simple solitaire, so it helps to get the fit right from the start.
East-west settings, the stone turned sideways
The other design that has moved quickly is the east-west setting. Instead of the stone sitting upright along the finger in the usual north-south direction, it is rotated ninety degrees to lie horizontally across the finger. It is a small change that transforms the whole silhouette, giving a clean, modern, slightly architectural look.
The style had been building for a while and accelerated in 2025 after Zendaya's engagement ring, a cushion-cut diamond set east-west, became widely known. It works most naturally with elongated shapes, so oval, emerald, marquise and radiant cuts all sit well turned on their side, and the horizontal line makes the stone appear to stretch across more of the finger.
Here is the part most guides skip, and it matters if you are commissioning one. An east-west stone cannot simply be dropped into a standard setting. The girdle of the diamond, the edge where the top and bottom meet, sits at a different angle when the stone is rotated, so the prongs or bezel have to be built specifically for that orientation. It is a genuine piece of bench engineering rather than an off-the-shelf mount. The visual payoff is large for what is a fairly subtle change, but it is worth knowing that a well-made east-west ring is a made-to-measure piece. A slim bezel or a hidden halo can add security without competing with the clean line.
The hidden halo, a detail only the wearer sees
The classic halo, a ring of small diamonds circling the centre stone, softened in popularity for a while. What has taken its place is the hidden halo. The extra diamonds sit underneath the main stone rather than around it, so from above the ring looks clean and uncluttered, and the sparkle only reveals itself from the side.
The appeal is quiet rather than showy. It is a piece of luxury the wearer experiences up close rather than something projected outward, and that fits the wider mood of choosing a ring for yourself rather than for an audience. It also adds a little height and light to a solitaire without changing its shape from the front.
Elongated cuts and the oval's quiet takeover
Underneath the setting trends sits a bigger change in shape. Elongated cuts, led by the oval, have overtaken the round brilliant as the most chosen shape for the first time in decades. That is a significant flip after fifty years of the round leading.
The reasons are practical as much as fashionable. An oval looks larger than a round diamond of the same carat weight because the shape is drawn out, so it presents more size for the same spend. It also lengthens the finger, which flatters most hands. Marquise and elongated cushion cuts share those qualities and both are having a moment, helped along by a broader vintage influence.
The specialist caveat here is one we mention at every consultation. Elongated shapes are not given a cut grade on their report in the way round diamonds are, and every oval, pear and marquise carries a degree of bowtie, a shadow shaped like a bow that runs across the centre. Good cutting keeps it faint. Poor cutting leaves a dark band you will notice every day. No certificate warns you about it, so the only reliable test is to look at the stone in normal light and watch whether it stays bright as you move your hand.
Sculptural gold and the return of substance
After years of ultra-fine bands, metal is having its say again. Chunkier profiles, cigar bands, smooth domed bombé shapes and sculptural forms are appearing, where the metalwork carries as much of the design as the stone. Yellow gold has moved back to the front, now the most chosen metal for engagement rings in the UK, often paired with vintage-leaning details like milgrain edges or old European and old mine cuts. Mixed metals, yellow gold with white or rose, add contrast for those who want it.
One practical note on the warmer, softer metals. Higher-carat yellow gold is a softer metal than platinum, so a bold gold band will show wear and marks a little more readily over the years. That is not a reason to avoid it, and it is easily kept in good order. It is simply worth knowing if your days are hands-on, since it feeds into how often the piece will want a polish, something covered under our Ever After Warranty.
What the trends mean if you are choosing a lab-grown diamond
Most couples now start with a lab-grown centre stone, and there is a recent change worth understanding, because it affects the paperwork you will see. As of 1 October 2025, GIA stopped applying the traditional 4Cs to lab-grown diamonds. Rather than a detailed colour and clarity grade, a lab-grown stone assessed by GIA is now described simply as Premium or Standard, or given no assessment at all if it falls below the threshold. GIA's reasoning is that the vast majority of lab-grown diamonds now cluster in a very narrow, high-quality range, so the fine gradations built for natural diamonds no longer tell you much.
In practice this means two things for you. First, you will often see lab-grown stones graded by IGI instead, which still issues a detailed report, so an IGI report on a lab-grown diamond is entirely normal and reputable. Second, and this is the important one, it makes seeing the stone matter more than ever. When a label reads simply Premium, the differences that remain, how well the stone is cut and how it handles light, are exactly the ones a report was never going to capture on a fancy shape anyway. The paperwork confirms what a stone is. Your own eyes, in daylight, tell you how it will actually look on the hand.
Choosing a trend that will still feel right in ten years
The rings that look timeless a decade later are rarely the ones that matched the trend chart perfectly. They are the ones that matched the person wearing them. A trend is a useful starting point, not a template to copy exactly, and the version that lasts is usually the one adapted to suit the wearer's hand, taste and daily life.
So use these styles as a way in rather than a rule. If you love the meaning of a toi et moi, build it around proportions that suit you. If the east-west look appeals, choose a shape that carries it. And whatever draws you, see it in person before you commit, because a photograph flattens the two things that decide whether you will love a ring for life, how it sits on your own hand and how the stone behaves in real light.
That is exactly what a consultation is for. Our showroom at 35 Frederick Street in Birmingham's Jewellery Quarter is an unhurried place to try these styles on and compare them side by side, with no obligation to decide anything on the day. You can book a consultation whenever you are ready.
