I’ll admit, the first time I saw a lab diamond under a jeweller’s loupe, I couldn’t tell the difference. Neither could the gemologist standing beside me. “That’s the point,” she laughed. “You shouldn’t be able to.”
Here’s the science bit, in plain English. Lab made (or lab created) diamonds are grown using the same natural process that forms mined diamonds — carbon, heat, and pressure — just accelerated and controlled inside a high-tech laboratory. The result? The same sparkle, hardness, and brilliance. In fact, gemological institutes like the GIA officially classify them as diamonds. The only difference lies in origin, not quality.
It’s a bit like the difference between rainwater and bottled water: both pure, just collected differently.

Why Aussies are falling in love with lab created diamonds
There’s something about the Australian mindset — practical, down-to-earth, and quietly ethical — that fits perfectly with this new wave of diamond shopping. Over the last few years, I’ve seen a growing awareness about sustainability and supply chains. People want to know where their products come from, especially when it comes to something as symbolic as an engagement ring.
Mining has long been a sensitive topic here, and while the diamond industry has made improvements, there are still environmental concerns and human rights issues attached to certain sources overseas. For many couples, lab made diamonds offer peace of mind — the beauty and romance of a diamond, without the guilt or mystery behind it.
Honestly, that emotional reassurance matters. You’re not just buying a gem; you’re buying a story.
The price difference: not cheap, but smarter
Let’s talk about the other big reason people are switching — cost. I don’t love reducing something beautiful to a number, but when a natural diamond and a lab diamond are identical in appearance and composition, it’s hard not to compare.
Lab created diamonds typically cost 30–40% less than their mined counterparts. For a lot of young couples, that’s the difference between a 0.9-carat and a full-carat ring, or between a simple setting and a custom design.
One jeweller in Melbourne told me, “It’s not about buying cheaper — it’s about getting better value.” That stuck with me. With that price difference, people are often choosing higher quality cuts or settings, or even pairing their stone with a unique design rather than a stock standard ring.
If you’re curious (and maybe even ready to start exploring), you can actually buy lab made diamonds directly through reputable jewellers who specialise in sustainable, ethically sourced stones. It’s a surprisingly smooth experience, and the customisation options are incredible — something you don’t always get with traditional retailers.
What the critics say (and why most are changing their tune)
When lab diamonds first hit the mainstream, there was plenty of scepticism. Some industry veterans argued they wouldn’t hold value. Others worried it would “dilute the romance” of a mined diamond.
But here’s the thing: times have changed. Today, the conversation is less about resale value — let’s be honest, most people don’t buy engagement rings as an investment — and more about emotional and ethical value.
Even major jewellers have started incorporating lab created diamonds into their collections. The younger generation, especially millennials and Gen Z, see them as modern luxury — transparent, tech-driven, and socially conscious.
A fashion stylist I spoke to recently said it perfectly: “It’s not about tradition anymore. It’s about alignment — aligning your choices with your values.”
The craftsmanship still matters
Here’s something I didn’t expect to discover: while the diamond itself is created in a lab, the artistry that turns it into a ring or necklace remains every bit as handcrafted. The cutting, polishing, and setting are still done by skilled jewellers — often the same experts who work with mined stones.
That human touch doesn’t go away; it’s just applied to a different kind of material. I watched a diamond setter at work one afternoon — his focus so intense, his hands steady as he placed a lab diamond into a gold band. He looked up at me and said, “People forget, it’s not just about the stone. It’s about what we do with it.”
That stuck with me.
The emotional shift: from status to symbolism
There’s something subtly beautiful happening in the way people view diamonds now. For decades, diamonds were seen as a status symbol — the bigger, the better, the pricier, the more love it must represent. But lately, I’ve noticed a quiet rebellion against that idea.
Couples today seem to want their rings to reflect who they are, not what they can afford. Choosing a lab created diamond isn’t about cutting corners — it’s about making a statement: that love doesn’t need to come at someone else’s expense.
It’s not a compromise. It’s a conscious choice.
How technology changed romance
It still amazes me that something so romantic could come from such cutting-edge technology. The science behind these diamonds is extraordinary — carbon atoms layered in perfect formation inside plasma reactors, replicating nature’s process atom by atom.
But the magic, to me, is in how it bridges two worlds: science and emotion. It’s a reminder that innovation doesn’t have to take away from meaning. It can add to it.
We’ve reached a point where you can celebrate your love story with something sustainable, beautiful, and entirely conflict-free. And in a world where so much feels mass-produced or artificial, that feels refreshingly authentic.
If you’re keen to explore more about how your style and personality can guide your choice, this piece on lab created diamonds has some genuinely insightful design tips that go beyond the usual “round vs. princess cut” chat.
What to look for when buying a lab diamond
If you’re considering making the leap, here are a few practical pointers I picked up along the way:
- Check certification – Make sure the stone is certified by GIA, IGI, or GCAL. These independent labs verify that the diamond meets international standards.
- Understand the 4Cs – Cut, colour, clarity, and carat weight still apply. Don’t assume every lab diamond is flawless (though many are remarkably close).
- Ask about growth method – There are two main techniques: HPHT and CVD. Both produce excellent results, but CVD tends to create slightly cleaner stones.
- Think about design – Lab diamonds open the door to customisation. Don’t be afraid to experiment with modern settings, coloured metals, or unique shapes.
- Buy from trusted jewellers – The best ones are transparent about sourcing, offer lifetime warranties, and have clear return policies.
The environmental side
Let’s talk footprint. While diamond mining can require moving tonnes of earth and consuming significant energy, lab production is far more efficient. It’s not perfect — growing diamonds still takes power — but many labs now use renewable energy sources and closed-loop systems to minimise waste.
According to one sustainability report I read, the average lab diamond uses about seven times less water and releases less than half the carbon emissions of a mined diamond.
That doesn’t just sound good on paper — it feels good in practice. Especially if you’re planning a wedding or engagement that already carries a financial and environmental cost.
Will lab diamonds ever completely replace mined ones?
Probably not. There will always be collectors, romantics, and traditionalists who prefer the natural rarity of mined stones. And that’s okay.
But what’s clear is that lab diamonds aren’t just a passing trend — they’re a shift in how we define luxury. The new luxury isn’t about scarcity. It’s about ethics, innovation, and personal meaning.
The fact that you can now choose a diamond that’s both stunning and sustainable feels like progress — the kind of progress that actually makes sense.
Final thoughts: beauty, evolved
After weeks of research, interviews, and probably too many cups of coffee, I’ve come to a simple conclusion: lab diamonds aren’t just about science or savings. They represent a quiet evolution in how we express love, style, and responsibility.
It’s easy to romanticise the past, but I think there’s something even more romantic about looking forward — about embracing new ways to celebrate life’s biggest moments without compromise.
Whether you’re planning to buy lab made diamonds for an engagement, anniversary, or just because you can, what matters most is that it reflects your story — your values, your personality, your love.
