A few years ago, if someone had mentioned lab grown diamonds to me, I probably would’ve pictured some kind of synthetic gem — maybe a bit shiny, a bit glassy, but definitely not the real deal. Turns out, I couldn’t have been more wrong.
Today, lab grown diamonds are turning the jewellery world on its head — and not just because they’re more affordable. They’ve sparked a quiet revolution in how Australians think about love, luxury, and even responsibility. Whether it’s an engagement ring or a simple pair of studs, the story behind the stone has become just as important as its sparkle.
Well, here’s the thing: the more you learn about lab grown diamonds, the more sense they make.

What Exactly Are Lab Grown Diamonds?
Let’s clear this up first. Lab grown diamonds aren’t imitations or “fakes.” They’re chemically, physically, and optically identical to mined diamonds. The only difference is where they come from — the Earth’s crust or a modern lab.
Scientists replicate the natural diamond-forming process using high pressure and high temperature, or a process called chemical vapour deposition (CVD). The result? A diamond so pure it can often outshine its mined counterpart. Jewelers even need advanced equipment to tell them apart.
When I first saw one up close, I honestly couldn’t believe it wasn’t mined. The clarity was stunning. And the fact that it hadn’t come from deep mining operations — often linked with environmental and ethical issues — just made it all the more appealing.
Why Australians Are Switching to Lab Grown Diamonds
1. They’re More Affordable (But Still Luxurious)
Let’s be real: cost matters. Especially when you’re planning an engagement or special occasion. On average, lab grown diamonds cost 30–50% less than mined ones. That means you can either save money or go bigger — a win either way.
But it’s not just about saving. Many couples say they love being able to design their dream ring without compromising on quality or conscience. If you’ve ever tried to buy lab grown diamonds online, you’ll know there’s a huge range of custom options available now — everything from carat size to cut to colour, often tailored to your budget and style.
It’s made luxury feel a bit more accessible, and honestly, a bit more modern too.
2. They’re Ethically and Environmentally Responsible
This is the big one. Mining for diamonds, as beautiful as the stones are, comes with a heavy environmental footprint — massive land disruption, carbon emissions, and sometimes troubling labour practices. For a long time, consumers didn’t have much choice. But now, there’s a genuinely sustainable alternative.
Lab grown diamonds require no mining. They use significantly less water, and their carbon footprint is a fraction of traditional mining operations. Some producers even run entirely on renewable energy.
It’s a shift that resonates deeply with young Australians, especially those who care about sustainability. A lot of couples I’ve spoken to have said they couldn’t imagine starting their marriage with a stone that came at someone else’s expense.
It’s not about guilt — it’s about feeling good about what you wear.
3. They’re Scientifically Fascinating
I’ll admit it — I’m a bit of a nerd for this part. There’s something wildly poetic about creating diamonds — the symbol of eternal love — using human innovation and science. It’s a reminder that beauty and technology can coexist, that progress doesn’t have to mean losing meaning.
In fact, the precision involved in growing diamonds is so advanced that scientists can now create stones of exceptional purity — often higher than what’s found in nature. Some high-end jewellers even argue that lab grown diamonds are better because they can be engineered for flawlessness.
4. They Come With Full Transparency
One of the best things about buying lab grown is knowing exactly what you’re getting. Every stone comes with detailed certification and traceability. There’s no mystery about origin, no murky supply chain — just a straightforward, verifiable process.
In a world where consumers are increasingly skeptical of “greenwashing,” that kind of honesty feels refreshing. It’s also why so many established jewellers in Australia have started offering both lab and mined options — giving customers the power to choose.
The Emotional Side: Do Lab Grown Diamonds Feel the Same?
This is something people often ask — especially when it comes to engagement rings. Is the emotion different when the diamond isn’t “from the earth”?
Personally, I think love stories aren’t defined by geology. They’re defined by meaning. If anything, lab grown diamonds add a new layer of intention. You’re choosing a stone that reflects not just commitment, but consciousness — love that’s thoughtful, modern, and future-facing.
I remember interviewing a couple in Melbourne who’d designed their engagement ring using a lab grown diamond. When I asked if it felt any less “real,” they laughed. “It feels more real,” they said. “Because it represents our values.”
That stuck with me.
The Design Possibilities Are Endless
Here’s something that often surprises people: because lab grown diamonds are more affordable, they actually open up creative possibilities. Couples can invest in custom designs, unusual cuts, or pairing their diamond with unique metals like rose gold or platinum without blowing their budget.
It’s led to a rise in fully personalised rings — where every detail tells part of the story. Some even engrave the date the diamond was “grown,” turning science into sentiment.

The Investment Question: Are Lab Grown Diamonds Worth It Long-Term?
This one’s tricky, and it depends on what “investment” means to you.
If you’re talking emotional value, absolutely. Lab grown diamonds are every bit as meaningful and durable as mined ones. They’re forever stones — just as strong, just as beautiful.
Financially, though, it’s a bit different. Mined diamonds have a long-established resale market, while lab grown stones are still finding their footing. Prices have dropped slightly in recent years as production scales up, which means resale isn’t really the main motivation.
But let’s be honest — most people aren’t buying engagement rings to resell them. They’re buying them for what they represent. And in that sense, the return on investment is priceless.
The Australian Jewellery Industry Is Catching On
In the past five years, Australia’s jewellery landscape has shifted dramatically. Major retailers, once hesitant, now proudly display lab grown collections alongside mined diamonds. Independent designers are embracing them too — using the technology to craft more innovative and sustainable pieces.
It’s not a passing trend; it’s a generational shift. Younger buyers are asking smarter questions and making more conscious choices. They don’t see lab grown as “less than” — they see it as next-gen luxury.
Even traditionalists are coming around. One Sydney jeweller I spoke with described the change as “the biggest shake-up since the introduction of synthetic sapphires decades ago — except this time, it’s not imitation, it’s evolution.”
How to Choose the Right Lab Grown Diamond
If you’re thinking of taking the plunge, here’s what I’d suggest:
- Do your homework. Make sure you’re buying from a reputable jeweller with proper certification (like GIA or IGI).
- Look at the 4Cs — cut, colour, clarity, and carat — just as you would with any diamond.
- Ask about the growth method. CVD diamonds generally have fewer metallic inclusions than HPHT, though both can be top quality.
- Consider custom design. Since you’re saving money on the stone, you can put more into a bespoke setting or band.
- Trust your eyes and heart. Sometimes the right diamond just feels right. You’ll know.
A Shift in What “Luxury” Means
Luxury used to mean rare, expensive, exclusive. But in 2025, it’s also about ethics, sustainability, and self-expression. Lab grown diamonds fit perfectly into that redefined space — where conscious choices and beautiful craftsmanship coexist.
It’s not about replacing natural diamonds, but about expanding what’s possible. About giving people a choice that aligns with their values.
And maybe that’s the real beauty of it — knowing that your sparkle doesn’t come at the expense of someone else’s world.
Final Thoughts
When I first started researching lab grown diamonds, I thought I’d be writing about technology. Instead, I found myself writing about people — couples, designers, dreamers — all reimagining what love and luxury can look like.
Choosing to buy lab grown diamonds isn’t just a financial decision; it’s a statement. A quiet but powerful one that says: we care about beauty, but we also care about impact.
So whether you’re shopping for a proposal, a gift, or just something special for yourself, it’s worth taking a closer look at these remarkable stones. You might find that the most meaningful sparkle comes from not just what’s inside the diamond — but what it stands for.
