2026 Engagement Ring Trends: What's Actually In Style This Year

Last updated July 2026

Engagement ring trends move fast, and a lot of "trend" content online is just recycled opinion. Here's what's actually happening, backed by real 2026 data from The Knot's Real Weddings Study and current retail figures, alongside what we're seeing directly with clients at our Wembley showroom.

1. Lab-Grown Diamonds Have Fully Crossed Into the Mainstream

This isn't really a "trend" anymore, it's the current market reality. The Knot's 2026 Real Weddings Study found lab-grown diamonds now account for 61% of engagement ring centre stones in the US, a 239% increase since 2020, with UK retail data putting adoption even higher, around 70%. Average carat size for lab-grown purchases now sits around 1.9 to 2 carats, noticeably larger than the typical mined stone, at a lower average total spend.

The reason cited most consistently by industry analysts: economic pragmatism. More carat, better colour, higher clarity, for meaningfully less money, without compromising on what the ring actually looks like.

💎 A favourite in this category: our Luna Oval Solitaire Ring, clean, minimal and timeless.

2. Oval Is Closing In on Round, and Elongated Shapes Keep Growing

Round brilliant remains the single most popular shape, but its lead has narrowed considerably, current data puts round at roughly 26% of purchases against oval at around 25%, a gap that's nearly closed entirely. Industry commentators have taken to calling this the "Hailey Bieber effect," referencing the visibility of her oval engagement ring.

Beyond oval, the shapes showing the fastest growth are emerald cut, marquise, and elongated cushion (a modern take on the antique old-mine cut). All three share the same practical appeal: more visible surface area per carat, which reads as a larger stone for the same weight.

3. Bezel and Half-Bezel Settings Are Genuinely Surging

This is one of the clearest, most data-backed trends for 2026. UK retail figures show rubover (bezel-style) settings up roughly 100% year over year, and bridal designers report the same pull in the US, a deliberate move away from delicate prong settings toward something more secure for daily wear.

What's driving it: bezel settings protect the stone significantly better day to day, and they pair particularly well with round, oval and emerald cuts (full bezel), or marquise and pear shapes (half or three-quarter bezel, which exposes more of the stone while still adding protection).

🌟 A top pick: our Solara Oval Half Bezel Ring.

4. Yellow Gold Has Genuinely Taken Over Half the Conversation

Yellow gold has more than doubled in popularity over the past five years and now sits at roughly 39% of engagement ring purchases, closing in on white metals, which still lead at around 48% combined (platinum and white gold together). Mixed-metal designs, a yellow gold band with a white gold or platinum head, for example, are increasingly common too, largely because couples want a ring that coordinates with the rest of the jewellery they already wear daily rather than standing apart from it.

Coloured lab-grown centre stones are part of the same broader shift: sales of coloured diamonds are up meaningfully year over year, as couples move away from the assumption that "diamond" automatically means colourless.

5. Halo Settings: A Genuine Correction, Not a Trend Line

Worth being precise here, since a lot of trend content gets this wrong: halo settings actually declined through 2025, down to roughly 5.3% of sales from around 9% the year before. What's more accurate to say for 2026 is that a halo revival is anticipated, driven by a broader swing toward old-money and vintage-inspired styling, rather than halos currently being "everywhere." If you're drawn to a halo, you're ahead of a possible resurgence rather than following a dominant current trend, which is a perfectly good reason to choose one, just worth knowing accurately.

6. Solitaires Still Lead, But Diamond Bands Are the Fastest-Growing Category

The classic solitaire remains the single most popular engagement ring style overall, at around 40% of sales, though that's down from close to 47% the year before as couples personalise the format with curved bands, hidden details and more sculptural silhouettes. The standout growth story is diamond band rings specifically, up from around 22% to 34% of sales year over year, a real shift toward more decorative, statement-led designs rather than a plain metal band beneath the centre stone.

7. Custom Design Is the Default, Not the Exception

Couples are shopping together far more than in previous years, current data shows the person receiving the ring is involved in choosing it close to 80% of the time, with a meaningful share of couples shopping for it jointly from the outset. Lab-grown diamonds and moissanite have made full customisation, stone shape, cut quality, metal, prong style, secret details, genuinely accessible rather than a premium add-on. We build rings from scratch with clients regularly, and this is now the norm we design around, not the exception.

What This Means If You're Shopping in 2026

The data points in a consistent direction: better value on the stone (via lab-grown adoption) is being redirected into more considered design, thicker bands, bezel settings, mixed metals, personalisation, rather than simply spending less overall. That's a genuinely different shopping mindset from a decade ago, and it's exactly the kind of conversation worth having with a jeweller who designs pieces rather than just sells off a shelf.

A note on the data: the specific percentages above are drawn primarily from US and UK studies (The Knot's 2026 Real Weddings Study and UK retail figures), since consolidated Australian-specific data of this depth isn't publicly available. The directional trends, lab-grown adoption, elongated shapes, bezel settings, yellow gold, are consistent with what we're seeing directly with clients at our Wembley showroom.
