A few years ago, I was helping a close friend pick out her engagement ring — one of those “big life moments” that somehow ends up feeling both thrilling and utterly overwhelming. We’d visited a few jewellers around Melbourne, browsed endless designs online, and debated every cut and setting under the sun. But what really caught her attention wasn’t the sparkle of a traditional mined diamond. It was something a bit different — lab diamond bridal sets.
At first, she was sceptical. “Are they real diamonds though?” she asked, peering at a flawless round cut under the jeweller’s light.
The jeweller smiled. “They’re as real as any diamond you’ve ever seen — just born differently.”
That moment stuck with me. Because what was once considered a niche or “alternative” choice has now become a full-blown movement among modern Australian couples.
A Changing Tradition
There’s a quiet revolution happening in the world of bridal jewellery — and it’s surprisingly down-to-earth. For decades, the diamond engagement ring has been the symbol of everlasting love. But traditions evolve, and today’s couples are far more thoughtful about where their money goes, what their jewellery represents, and how their choices impact the world.
Lab created diamonds, for instance, aren’t just a clever bit of science — they’re a statement. They carry the same chemical composition, brilliance, and fire as mined diamonds, but without the environmental toll or ethical baggage often associated with traditional mining.
It’s no wonder lab diamond bridal sets have become such a popular choice in Australia. They’re elegant, sustainable, and — let’s be honest — they often cost a fraction of what you’d pay for a mined equivalent.
And if there’s one thing we Aussies appreciate, it’s getting quality without compromise.
What Exactly Are Lab Diamond Bridal Sets?
Let’s break it down. A bridal set typically includes an engagement ring and a matching wedding band — designed to sit perfectly together, like puzzle pieces. The beauty of a bridal set is the harmony between the two rings; they complement each other in shape, metal, and design, creating a cohesive look that feels intentional and timeless.
When we talk about lab diamond bridal sets, we’re talking about the same concept, but crafted using lab created diamonds instead of mined ones.
Here’s the science-y bit (don’t worry, I’ll keep it simple).
Lab diamonds are grown in controlled environments that replicate the conditions deep within the Earth’s mantle — high pressure, high temperature. The result? A diamond that’s optically, physically, and chemically identical to one pulled from the ground.
The difference is in the origin story, not the sparkle.
Why Modern Couples Are Making the Switch
I’ve spoken to dozens of couples over the past year — through interviews, at weddings, even just casual chats over brunch — and the same themes keep coming up.
1. Ethical Peace of Mind
Many couples today want to know the “story” behind their diamond. Mined stones often have a murky supply chain, and while there are certifications to reduce conflict diamonds, the system isn’t flawless.
Lab created diamonds offer full traceability. You know exactly where it came from, how it was made, and under what conditions. There’s a comfort in that transparency.
2. Environmental Considerations
Mining is resource-heavy — tonnes of earth are displaced for a single carat of diamond. In contrast, lab diamonds require significantly less energy and water, and have a far smaller carbon footprint.
In a world that’s increasingly conscious about sustainability, choosing a lab diamond feels like a small but meaningful act of responsibility.
3. Better Value for Money
This one always surprises people: you can often get a 30–40% larger or higher-quality diamond for the same budget if you go lab-grown. That means more sparkle without breaking the bank.
It’s not about “cheap alternatives” anymore — it’s about smarter luxury.
4. Design Freedom
Because lab diamonds are more affordable, couples have the freedom to play with styles they might not have considered before — from elaborate halo settings to coloured stones or vintage-inspired designs.
The creativity we’re seeing in lab diamond bridal sets is nothing short of breathtaking.
The New Face of Romance
There used to be this old-school idea that a diamond’s value was tied to how rare or “natural” it was. But love itself isn’t about rarity — it’s about choice. Choosing someone every day. Choosing to build a future together.
And that’s what makes lab diamonds so symbolic for many younger couples — they represent a conscious, modern kind of love. One that’s grounded in shared values, not just tradition.
I spoke recently to an Adelaide-based jeweller who’s been crafting engagement rings for over 25 years. He told me, “Ten years ago, people wouldn’t even ask about lab diamonds. Now, nearly half my clients do — and they’re proud of that choice.”
He paused, then added, “It’s not just a trend. It’s a mindset shift.”
What You Might Not Know About Lab Created Diamonds
Here’s where things get interesting. You might assume lab diamonds are a new invention, but scientists have been growing them since the 1950s. Back then, they were mainly used for industrial purposes — cutting tools, electronics, that sort of thing.
It wasn’t until the last decade that technology advanced enough to create gem-quality stones indistinguishable from mined ones.
Today’s lab created diamonds are graded and certified by the same gemological institutes (like GIA and IGI) using the same criteria: the famous 4Cs — cut, colour, clarity, and carat weight.
So if you buy a 1-carat lab diamond with excellent cut and clarity, it’s every bit as “real” and brilliant as a mined diamond of the same grade.

How to Choose the Perfect Lab Diamond Bridal Set
Alright, let’s get practical. If you’re considering a lab diamond bridal set, here are a few tips that might save you a lot of time (and maybe a few dollars).
1. Think About Your Lifestyle
Are you someone who works with your hands? Do you prefer minimalist jewellery or something more ornate?
Your daily routine should influence the design. For instance, if you’re active, a bezel setting might be more practical than a high-prong one that can catch on things.
2. Match Metals Thoughtfully
White gold, yellow gold, platinum, or rose gold — each metal brings out different qualities in a diamond.
Rose gold, for example, pairs beautifully with oval or cushion-cut diamonds, adding warmth and romance. Platinum, on the other hand, gives a crisp, modern finish.
3. Consider the Set as a Whole
Because bridal sets are designed to be worn together, make sure the engagement ring and band fit seamlessly. Some couples even choose to design custom sets that incorporate symbolic details — a hidden gem, engraving, or intertwined bands.
4. Trust a Reputable Jeweller
This is key. Always buy from a jeweller who provides proper certification for lab diamonds and transparent details about the metal quality, craftsmanship, and warranties.
The Emotional Side of It
There’s something genuinely heartwarming about how this shift is unfolding. What I love most about the rise of lab diamonds isn’t just the sustainability factor — it’s the sentiment behind it.
It shows how couples are rewriting the rules, making love feel personal again. No pressure to fit a certain budget. No expectation to conform to what previous generations considered “the norm.”
When you slip on a ring that you chose consciously — one that reflects both your style and your values — it becomes more than jewellery. It becomes a story you’ll actually want to tell.
The Future Is Bright (and Brilliant)
Experts predict that within the next decade, lab created diamonds could make up over half of all new diamond sales globally. That’s not just a passing trend — that’s a transformation in how we define luxury.
Australia, with its strong sustainability ethos and love for craftsmanship, is leading the charge. Independent jewellers across Sydney, Perth, and Brisbane are now offering bespoke lab diamond bridal sets that rival anything you’d find in Paris or New York.
What’s fascinating is that this shift is happening quietly, without fanfare. It’s not about bragging rights — it’s about authenticity.
Final Thoughts: A New Kind of Forever
At the end of the day, diamonds have always been about love — enduring, luminous, unbreakable. But love itself evolves, and so does how we express it.
Choosing a lab diamond bridal set isn’t just about being trendy or eco-conscious. It’s about celebrating the idea that beauty and responsibility can go hand in hand.
As I watched my friend finally say “yes” to her ring — a stunning emerald-cut lab diamond framed in rose gold — she smiled and said, “It just feels right.”
