Quick answer: The most famous royal engagement rings belong to Catherine, Princess of Wales (a 12-carat oval Ceylon sapphire once worn by Princess Diana), Meghan, Duchess of Sussex (a Botswana diamond flanked by two stones from Diana's own collection), Grace Kelly (a 10.48-carat Cartier emerald-cut diamond from Prince Rainier III of Monaco), Jacqueline Kennedy (a Van Cleef & Arpels "toi et moi" diamond and emerald, often grouped with royal icons for its influence) and Pippa Middleton (an Asscher-cut diamond inside an Art Deco halo). Between them, these five rings have shaped almost every major engagement ring trend of the last seventy years, from sapphire halos to three-stone symbolism.

Why Royal Engagement Rings Fascinate Us
There's a reason we can picture these five rings without needing a photograph. A royal engagement ring is never just a piece of jewellery — it's a public announcement, a piece of family history, and very often a small act of quiet rebellion, all set into a single stone.
Part of the fascination is craftsmanship. Each of these rings was made by a jeweller working at the very top of their trade — Garrard, Cartier, Van Cleef & Arpels — at a moment when every detail had to be right, because the whole world would eventually see it. Part of it is symbolism: a sapphire chosen to honour a mother, a diamond sourced from a country that meant something, a redesign that marked a change in status. And part of it, frankly, is fashion. When a future queen or a Hollywood star steps out with a new ring, engagement ring sales for that stone shape can shift within days.
What's most interesting is how differently each of these five women wore her ring. Some chose tradition. Others broke it entirely. That contrast is exactly what makes this such a rich subject — and such a useful one, if you're currently choosing a ring of your own.
Google searches for "sapphire engagement ring" spiked dramatically in the days after Prince William and Kate Middleton's engagement was announced in November 2010 — a pattern jewellers still refer to informally as "the Kate effect".

Catherine, Princess of Wales
No royal ring has shaped modern bridal jewellery quite like this one. At its centre sits a 12-carat oval Ceylon sapphire, chosen for its rich, glowing blue, surrounded by a cluster of 14 round diamonds and set in 18-carat white gold.
The ring's story actually begins over a century before it was made. In 1840, Prince Albert commissioned Garrard to create a sapphire-and-diamond brooch for Queen Victoria as a wedding gift. That brooch became a template. When Prince Charles proposed to Lady Diana Spencer in February 1981, Garrard offered her a tray of rings to choose from — and, breaking with the tradition of a bespoke royal commission, Diana picked this one, straight from stock, almost immediately.
Nearly thirty years later, Prince William proposed to Kate Middleton in Kenya using his late mother's ring. It was a deeply personal choice, and one William later said felt like a way of making sure Diana "didn't miss out" on the moment. The couple announced their engagement in November 2010, and the ring reappeared in public life for the first time since Diana's death in 1997.
Why it became iconic
Two things happened almost overnight. First, sapphire engagement rings — a genuinely unusual choice for a royal bride in 1981 — became one of the most requested styles in the trade, a pattern that repeated itself even more strongly after 2010. Second, the halo-style cluster setting, where smaller diamonds frame a larger coloured stone, became a design language of its own, one you'll still see on engagement rings today.
Sapphire sits at 9 on the Mohs hardness scale, second only to diamond. That's part of why this design has aged so well through four decades of daily wear — sapphire genuinely can handle everyday life.
Modern alternatives
You don't need a royal budget to borrow this idea. A Ceylon or Kashmir-inspired blue sapphire, surrounded by a diamond halo in white gold or platinum, delivers the same silhouette at a fraction of the cost — particularly if you consider a slightly smaller centre stone or a lab-grown diamond surround. Browse our sapphire engagement rings or explore halo settings to see how the look translates.
Who should choose this style? Anyone drawn to colour with heritage behind it, and anyone who wants a stone tough enough for daily wear without excessive maintenance.
Meghan, Duchess of Sussex
Prince Harry designed this ring himself, and every stone in it was chosen for a reason. The centre diamond, a cushion cut of roughly three carats, was sourced from Botswana — a country where the couple spent time together early in their relationship, away from the public eye. It's flanked by two smaller round diamonds taken from Princess Diana's personal jewellery collection, a deliberate way of including his mother in the moment.
The couple announced their engagement in November 2017, with the ring originally set on a plain yellow gold band, reportedly Meghan's favourite metal. In 2019, shortly after the birth of their son Archie, the band was quietly redesigned with a delicate pavé diamond setting, adding extra sparkle without changing the story the ring told.
What the three stones mean
Three-stone rings carry an old and fairly universal symbolism: past, present and future. In this case, the meaning runs deeper still — a stone for a shared memory, two stones for a mother who couldn't be there in person. It's a genuinely moving piece of design, and it's a large part of why trilogy rings surged in popularity after 2017.
If you're drawn to a Botswana-style stone for ethical reasons, ask your jeweller directly about provenance. Reputable suppliers can trace a diamond's country of origin, and Botswana in particular has strong regulatory oversight through the Kimberley Process.
Modern popularity
The three-stone silhouette suits almost any diamond shape — cushion, round, oval or emerald — and works beautifully with both natural and lab-grown centre stones. Explore our three stone rings to see the range of ways this design translates into everyday jewellery.
Who should choose this style? Couples who want their ring to tell a specific story — a place, a person, a memory — rather than simply following a trend.
Grace Kelly & Prince Rainier III
Before Grace Kelly became Princess of Monaco, she was one of Hollywood's biggest stars — which makes her engagement ring a genuine crossover moment between old Hollywood glamour and European royalty. Prince Rainier III first proposed with a ruby-and-diamond eternity band, its red and white stones a nod to the Monégasque flag. The ring the world remembers, though, arrived shortly after: a 10.48-carat emerald-cut diamond by Cartier, flanked by two tapered baguette diamonds, set in platinum.
Grace actually wore the ring on screen before she wore it as a princess. It appears, quite prominently, in her final film, High Society, filmed in early 1956 — meaning millions of cinema-goers saw the ring before the official announcement.
The craftsmanship behind an emerald cut
An emerald cut is a step cut, built from long, flat facets rather than the triangular facets of a brilliant. That construction produces a cooler, more architectural sparkle — think of it as flashes of light rather than constant fire — but it also means any inclusions are much easier to see. Cartier's willingness to set a stone this size, in this cut, tells you exactly how exceptional the diamond's clarity was.
Grace Kelly's ring is believed to be worth somewhere in the region of $38–39 million today, making it one of the most valuable engagement rings ever recorded — and it remains part of the Grimaldi family collection in Monaco.
Modern influence
The emerald cut has never really gone out of fashion since, and it's seen a significant resurgence over the past decade among couples who want a diamond with presence rather than maximum brilliance. If that appeals, our emerald cut engagement rings collection is a good starting point.
Who should choose this style? Confident, minimalist tastes — anyone who prefers clean architectural lines over maximum sparkle, and doesn't mind a diamond with slightly higher clarity requirements.
John F. Kennedy & Jacqueline Bouvier
Jacqueline Kennedy was never technically royalty, but her engagement ring is so frequently grouped with royal icons that it would feel like an omission to leave it out — and once you know the story, it's easy to see why.
In 1953, JFK gave Jackie a Van Cleef & Arpels ring in the "toi et moi" style — French for "you and me" — featuring two centre stones side by side rather than one. Hers paired a 2.88-carat emerald-cut diamond with a 2.84-carat emerald-cut Colombian emerald, set on a bypass band of yellow gold and platinum, accented with baguette diamonds and emeralds.
Nearly a decade later, in 1962, by then First Lady, Jackie sent the ring back to Van Cleef & Arpels for a redesign. The baguettes were replaced with marquise-cut diamonds arranged in a laurel-wreath pattern beneath the two main stones — a subtly more confident, more public version of the same ring.
Why the design still resonates
A toi et moi setting is unusual by nature: two different stones, given equal weight, sitting side by side rather than one dominating the other. It's a design that resists the idea of a single "perfect" diamond, which may be exactly why it feels so contemporary again today.
Toi et moi rings have had a genuine resurgence in recent years, with several high-profile engagements — including Megan Fox's toi et moi ring — bringing the two-stone silhouette back into the mainstream.
Who should choose this style? Anyone who wants something genuinely different from a single-stone ring, and likes the idea of pairing two gemstones — a diamond with a coloured stone, or two contrasting cuts — rather than choosing between them.
Pippa Middleton & James Matthews
Pippa Middleton's engagement ring quietly does something clever: it borrows the Art Deco language of the 1920s and makes it feel entirely current. At its centre is an Asscher-cut diamond, estimated at around three to three-and-a-half carats — a square step cut with cropped corners, closely related to the emerald cut but more geometric in outline. It sits inside an octagonal halo of smaller channel-set diamonds, set in platinum.
James Matthews proposed during a trip to England's Lake District in July 2016, and the ring was photographed publicly within days — inevitably drawing comparisons to her sister's famous sapphire.
Why the Asscher cut works so well here
The Asscher cut was developed in 1902 by Joseph Asscher, whose company later cut sections of the Cullinan diamond for the British Crown Jewels — a small but genuine royal connection woven into the design. Its deep step-cut facets create a distinctive hall-of-mirrors effect, quite different from the brilliance of a round or cushion cut, and the octagonal halo around it echoes the stone's own angular outline rather than fighting against it.
If you love this look, ask your jeweller to show you an Asscher cut and an emerald cut side by side. They're often confused, but the Asscher is more square and has a higher crown, giving it a noticeably different personality on the hand.
Modern elegance
This is a ring that photographs beautifully and wears well — the halo protects the centre stone and adds visual size without a large carat weight. See the style for yourself across our halo rings and vintage-inspired engagement rings.
Who should choose this style? Buyers who love vintage character but want the practicality and protection of a modern halo setting.

How Royal Engagement Rings Changed Modern Jewellery Trends
It's rare for five rings to shape an entire industry, but between them, this group genuinely has. Here's what's traceable directly back to royal influence.
The halo revival. Both Kate's sapphire cluster and Pippa's octagonal halo helped push halo settings from a niche vintage style back into mainstream demand, where they remain one of the most popular choices in the UK today.
Sapphire's return to fashion. Blue sapphire engagement rings were considered unusual before 1981. They are now one of the most requested coloured-stone alternatives to diamond, a shift that traces almost entirely back to this one ring.
The three-stone resurgence. Meghan's trilogy ring reintroduced an entire generation of buyers to the symbolism of a three-stone setting, and searches for "three stone engagement ring" rose sharply in the months following her engagement.
Emerald cuts, back in favour. Grace Kelly's ring set the template decades ago, but emerald-cut diamonds have seen a fresh wave of popularity recently, partly driven by a broader move toward vintage-inspired, architectural stone shapes.
Vintage revival. Pippa's Art Deco design and Jackie Kennedy's toi et moi setting both sit comfortably within a much larger current trend: a preference for antique-inspired cuts and settings over the standard modern round brilliant solitaire.
Ethical sourcing as a talking point. Harry's choice of a Botswana diamond, deliberately and publicly explained, helped normalise conversations about where a diamond actually comes from — something increasingly important to today's buyers.
⏳
What Makes a Royal Engagement Ring Timeless?
None of these five rings look dated, despite the oldest being nearly seventy years old. That's not an accident. A handful of design principles keep coming up.
Proportion over size. Every one of these rings is well-proportioned for the hand wearing it, rather than simply large. A well-balanced ring photographs and wears better than one chosen purely for carat weight.
Exceptional craftsmanship. Garrard, Cartier and Van Cleef & Arpels didn't cut corners because a client was famous — if anything, the opposite. Fine settings, secure claws and quality metalwork are what let a ring survive decades of daily wear.
Genuine meaning. A story behind a ring doesn't just make good press — it makes the design more durable, because sentiment doesn't go out of fashion the way trends do.
Quality over fashion. A well-graded diamond or a fine natural sapphire will always look right, regardless of which cut happens to be trending that year.
When you're choosing your own ring, ask yourself the same question a royal jeweller would: will this still feel right on your hand in twenty years? Trends fade. Good proportion and good craftsmanship don't.

Expert Jewellery Buying Advice
Whichever royal ring inspires you, the same practical checks apply before you buy.
Check stone durability
Diamond and sapphire (9–10 on the Mohs scale) handle daily wear well. Emerald is softer and more included by nature, so it needs a protective setting — a bezel or low-set mount rather than exposed claws.
Think about your actual lifestyle
An active job or hobby suits a lower-set, well-protected stone. A halo or bezel setting, like Kate's or Pippa's, offers more security than exposed prongs for everyday wear.
Insist on setting security
Ask your jeweller about prong gauge and how the centre stone is secured. A ring you'll wear every day should be checked for loose claws roughly once a year.
Always request certification
GIA and IGI are the two most widely trusted grading laboratories. Never buy a significant diamond without a current, independent grading certificate.
Understand gemstone quality
For coloured stones, ask about treatment. Most sapphires on the market are heat-treated to improve colour and clarity, which is standard practice — but it should always be disclosed.
Budget realistically
Decide your overall budget before you fall in love with a specific stone, and be clear on how much you want to spend on the centre stone versus the setting.
Consider a bespoke design
Many of the details that make these royal rings special — a specific stone origin, a family diamond, a meaningful setting detail — are only possible with a bespoke design rather than an off-the-shelf ring.
Plan for maintenance and insurance
Have your ring professionally checked and cleaned periodically, and get it independently valued and listed on your home contents insurance from day one. Our engagement ring cleaning guide covers the everyday basics.

Can You Recreate Royal Engagement Rings?
Yes — and you have more genuine flexibility than you might expect. You don't need to copy a design exactly to capture what makes it special.
Custom design. A skilled jeweller can take the elements you love — a sapphire halo, a three-stone trilogy, an Asscher cut inside an octagonal frame — and build them around your own hand, budget and taste, rather than reproducing a museum piece.
Lab-grown options. Lab-grown diamonds and sapphires are chemically, physically and optically identical to their mined counterparts, carry the same GIA or IGI certification, and typically cost significantly less — a practical way to reach a Grace Kelly-sized emerald cut on a realistic budget. Browse our lab-grown diamond jewellery.
Natural gemstones. If provenance and rarity matter to you, a natural Ceylon sapphire or a natural emerald-cut diamond carries the same character these royal stones did, simply at a scale that suits your budget.
Budget alternatives. A smaller centre stone in a halo setting, like Kate's or Pippa's, creates significant visual size for a fraction of the carat weight and cost of the original.

Frequently Asked Questions
Which royal engagement ring is most valuable?
Grace Kelly's 10.48-carat Cartier emerald-cut diamond is the most valuable of the five, with independent estimates placing it at around $38–39 million today. That's largely down to its exceptional size, clarity and the rarity of an emerald cut at that scale from 1956.
What ring did Princess Diana wear?
Princess Diana wore a 12-carat oval Ceylon sapphire surrounded by 14 diamonds, made by Garrard in 1981. The same ring was later given to Kate Middleton by Prince William, and it remains the ring Catherine, Princess of Wales, wears today.
Why did Prince William propose with Diana's ring?
William has spoken publicly about wanting his mother to be part of the moment, describing the choice as a way of making sure she "didn't miss out" on his engagement. It's widely seen as one of the most personal decisions in modern royal history.
What is a halo engagement ring?
A halo setting surrounds the centre stone with a ring of smaller diamonds, adding perceived size and extra sparkle. Both Catherine's sapphire cluster and Pippa Middleton's Asscher-cut ring use variations on this setting.
Are sapphire engagement rings durable?
Yes. Sapphire ranks 9 on the Mohs hardness scale, just below diamond, making it one of the most durable gemstone choices for a ring worn every day. It resists scratching extremely well, though it can still chip if struck at the wrong angle.
Can you recreate Kate Middleton's ring?
Yes. A natural or lab-grown oval sapphire, surrounded by a diamond halo and set in white gold or platinum, recreates the look closely. Carat weight and sapphire origin are the biggest factors affecting price, so a smaller centre stone is an easy way to adjust budget.
What does a three-stone ring symbolise?
Three-stone rings traditionally represent a couple's past, present and future. Meghan Markle's ring adds a further, more personal layer of meaning, with its side stones drawn from Princess Diana's own jewellery collection.
Which royal ring inspired modern engagement rings the most?
Catherine's sapphire halo is arguably the single most influential royal engagement ring of the last fifty years, credited with reviving both sapphire engagement rings and halo settings almost overnight after 2010.
What gemstone is best after diamonds?
Sapphire is generally considered the best alternative to diamond for daily wear, thanks to its hardness, wide colour range and relatively good value compared with emerald or ruby of similar quality.
Are royal engagement rings custom made?
Not always. Diana's sapphire ring was chosen from Garrard's existing stock rather than custom designed, which was considered unusual at the time. Meghan's ring, by contrast, was a fully bespoke commission designed by Prince Harry himself.
💬
Final Thoughts
What ties these five rings together isn't wealth or fame — it's that each one tells a genuine story, made with real craftsmanship, chosen for reasons that mattered to the people wearing them. That's the part worth borrowing, far more than any specific cut or carat weight.
Whether you're drawn to the quiet history of a sapphire halo, the personal symbolism of a three-stone trilogy, or the architectural confidence of an emerald cut, the same principle applies: choose the design that means something to you, made well enough to last. If you'd like help translating any of these looks into a ring of your own, our team is always happy to talk it through.
