I still remember the first time I held a diamond under the jeweller’s loupe — that tiny magnifying glass they wear like a badge of honour. The gem looked flawless, shimmering with the kind of light you only see in old movies. The jeweller told me it was a natural diamond, formed over billions of years, buried deep in the earth. Then, with a sly grin, he pulled out another gem. “Now guess which one’s real,” he said.
Honestly? I couldn’t tell. And I’ve been writing about fashion and lifestyle for years. That was the moment I realised this topic — lab made diamonds vs real — was far more complicated (and fascinating) than I thought.

The Diamond Dilemma: What Are We Really Paying For?
Let’s start with the basics. Traditional diamonds — the ones we often call “real” or “natural” — are formed deep underground, under immense heat and pressure, over millions (sometimes billions) of years. They’re mined, cut, and polished before finding their way into engagement rings and necklaces.
Lab made diamonds, on the other hand, are grown in controlled environments using advanced technology that replicates those same natural conditions. The result? A diamond with the same chemical, optical, and physical properties as the mined version. Yep, the same carbon structure, the same brilliance, the same hardness.
So, when someone asks, “Is a lab diamond real?” the honest answer is: yes, absolutely. It’s a diamond — not an imitation like cubic zirconia or moissanite. The main difference lies in the origin story.
How the Sparkle Is Born
There are two main ways to grow a lab diamond: HPHT (High Pressure, High Temperature) and CVD (Chemical Vapour Deposition).
HPHT mimics the natural formation process by applying intense heat and pressure to carbon, just like what happens underground. CVD, on the other hand, uses a carbon-rich gas that’s heated in a vacuum chamber, where carbon atoms slowly crystallise onto a diamond “seed.”
Both methods produce genuine diamonds — not lookalikes, not fakes. You might not know this, but some jewellers actually struggle to tell them apart without specialised equipment.
But Why the Debate?
If lab diamonds are real, why is there still so much fuss about “lab made diamonds vs real”?
Well, it comes down to perception, rarity, and emotion. Natural diamonds have long been marketed as symbols of eternity, romance, and exclusivity. The idea that a gem has been sitting in the earth for eons before being unearthed feels — well — poetic. There’s an emotional pull there that technology can’t quite replicate.
Lab made diamonds, meanwhile, appeal to a newer mindset. They’re often chosen by people who care about ethics, sustainability, and transparency. No mining. No environmental devastation. No questionable labour practices. Just science and sparkle.
That said, for some traditionalists, the story behind the stone still matters. One Sydney jeweller I spoke to said, “A mined diamond has history — it’s like holding a piece of the planet’s memory.”
Another customer, though, told me, “I’d rather my diamond be conflict-free and eco-conscious than ancient.”
And that’s the heart of it: values. It’s not just a question of science or sparkle — it’s what the diamond means to you.
The Price of Perfection
Here’s where things get interesting.
Lab made diamonds typically cost 30–50% less than mined ones. You can buy a bigger, higher-quality stone for the same budget. That’s a huge drawcard, especially for couples trying to balance wedding costs or first-home savings.
But the catch? Resale value.
Natural diamonds tend to hold value (though not as much as some people think). Lab made diamonds, being more affordable to produce, are dropping in price as technology improves. In other words, a lab diamond is a beautiful choice, but probably not an investment piece — at least not yet.
Still, let’s be honest: most people buying engagement rings aren’t thinking about resale. They’re thinking about the moment — the story, the love, the memory.
The Ethical Edge
This is where lab diamonds really shine (pun intended). Traditional mining can have devastating effects on the environment — massive land disruption, water pollution, and carbon emissions, not to mention the human cost in conflict zones.
Lab grown diamonds sidestep that entirely. They’re created with precision, using minimal water and no mining. For many eco-conscious Australians, that’s a deciding factor.
If you’ve ever looked into the environmental footprint of mined gems, you’ll know it’s not pretty. But lab-grown options are giving the industry a chance to change — to align luxury with sustainability.
For those wanting a deeper dive into the science and ethics behind lab made diamonds vs real, this resource breaks down how above-ground cultured diamonds are reshaping modern jewellery standards.
The Look: Can You Tell the Difference?
I actually tested this with a few friends — some fashion editors, a gemologist, and a jeweller’s apprentice. I handed them two identical rings: one with a mined diamond, one lab-grown. Out of seven people, only one guessed correctly.
To the naked eye, they’re indistinguishable. Even under magnification, the differences are microscopic — tiny growth patterns that only specialised instruments can detect.
So if your worry is that a lab diamond will “look fake,” you can relax. It’ll sparkle just as fiercely, catch the light the same way, and probably earn just as many compliments.
Shifting Trends: Why Younger Buyers Are Choosing Lab Diamonds
There’s a generational shift happening, and it’s fascinating to watch. Millennials and Gen Z shoppers are driving the surge in lab diamond sales.
Partly it’s about ethics and affordability, but it’s also about individuality. Instead of following the traditional “one-carat mined diamond” path, younger buyers are experimenting with fancy cuts, coloured stones, and custom designs.
And with lab diamonds, those possibilities open up. You can choose a pink or blue diamond without spending a small fortune. You can match your ring to your fashion aesthetic — vintage, minimalist, boho, or glam.
If you’re curious about matching your diamond style to your wardrobe, there’s a brilliant piece on lab diamonds and how to choose a ring that fits your personality. It’s a surprisingly practical read for anyone shopping for their first serious piece of jewellery.
The Emotional Factor
Now, here’s where the discussion gets personal.
When I interviewed a couple from Melbourne who recently got engaged, they told me they’d spent months researching mined vs lab diamonds. “At first, we thought a lab diamond wouldn’t feel special,” the bride-to-be admitted. “But then we realised — it’s the love that makes it special, not the rock.”
That stuck with me. Because at the end of the day, whether your diamond came from deep within the earth or from a high-tech lab, it’s still a symbol — a reflection of your story.
We humans attach meaning to things. That’s what makes jewellery magical.
A Quick Reality Check
To be clear, the natural diamond industry isn’t going anywhere. It’s massive, deeply rooted, and still highly valued for its rarity and heritage. But it’s also evolving — many major jewellers now offer both mined and lab-grown options, side by side.
This coexistence might just be the best outcome for everyone. Choice, transparency, and innovation — all without sacrificing the beauty we’ve cherished for centuries.
The important thing is to know what you’re buying and why. If you want a symbol of timeless natural wonder, go for a mined diamond. If you want ethical brilliance with modern flair, choose lab-grown.
Both are real. Both are stunning. Both can hold a lifetime of memories.
The Future of Diamonds in Australia
Australia’s diamond market is changing fast. Retailers across Sydney, Melbourne, and Brisbane are reporting record interest in lab-grown stones. Some boutiques are now fully dedicated to them.
This shift mirrors global trends — lab diamonds are projected to account for nearly half of all diamond sales by the end of the decade. And as technology advances, the line between “real” and “lab” will blur even more.
It reminds me of how electric cars or plant-based meats were once considered “alternatives,” but are now mainstream. That’s where we’re heading with diamonds, too — towards choice, not compromise.
So… Which Should You Choose?
Well, that depends on what matters to you.
If you love tradition, rarity, and the idea of owning a piece of Earth’s deep history, then a mined diamond will always have its place. It’s the old-school romantic option — like writing love letters by hand.
But if you’re drawn to innovation, ethics, and modern values, a lab-grown diamond might feel more aligned with who you are today. It’s forward-thinking luxury — sustainable, accessible, and every bit as beautiful.
Personally? I think there’s room for both.
A Final Thought
When I left that jeweller’s shop months ago, I kept thinking about how easily I was fooled by those two stones. One was born in the earth, the other in a lab — yet both caught the light in the same breathtaking way.
It made me realise something: beauty doesn’t need a backstory to be meaningful. It just needs to mean something to you.
So whether your diamond is mined or man-made, if it makes your heart skip a beat — that’s what truly matters.
