I’ve spent more than two decades behind a jeweller’s bench, squinting at tiny stones under bright lamps, coaxing metal into shape, and listening to customers as they work through one of the biggest emotional purchases of their lives. Engagement rings, anniversary necklaces, those “just because” earrings — they all come with stories. And over the past few years, I’ve noticed one conversation popping up more often than any other:
“Should I buy lab grown diamonds instead of mined ones?”
If you’d asked me that question a decade ago, I probably would’ve hesitated. Back then, lab diamonds weren’t taken seriously. Some customers thought they were fake. A few colleagues even rolled their eyes. But honestly? The industry has changed — dramatically. And I’ve changed my tune right along with it.
Today, lab grown diamonds don’t just sit beside natural stones as a “budget-friendly option.” They’ve become a genuine, credible choice for people who want brilliance, beauty, ethics, and value without the eyebrow-raising price tags. And from behind the bench, watching trends shift in real time, I can tell you this isn’t a passing fad. It’s a movement.
So let me walk you through what’s really driving Australians to buy lab grown diamonds, and why jewellers like me are now embracing them with open arms.

What Lab Grown Diamonds Actually Are (and Why They’re Not “Fake”)
You might not know this, but a diamond’s origin — whether it’s forged underground over billions of years or grown inside a high-tech chamber — doesn’t change its fundamental structure.
A lab grown diamond is a diamond.
Same carbon.
Same crystal structure.
Same sparkle that stops you in your tracks when the light hits just right.
The biggest difference? Time and location. Instead of being mined from deep beneath the earth, a lab grown diamond is cultivated using one of two technologies:
-
CVD (Chemical Vapour Deposition) – where a diamond seed slowly grows as carbon atoms accumulate in layers.
-
HPHT (High Pressure High Temperature) – which mimics the intense heat and pressure of the earth.
When customers see these diamonds under a loupe for the first time, they usually lean forward, squint, and say, “So… that’s really it?” And I have to smile, because I had the same reaction when I first inspected one nearly 15 years ago.
The Shift: Why People Are Leaning Toward Man Made Stones
I’ve been part of conversations on both sides of the counter — and trust me, the shift toward man made diamonds didn’t happen overnight.
But here’s what’s driving it:
1. Prices That Actually Make Sense
Well, in the jewellery world, “sensible pricing” sometimes feels like a myth. A mined diamond that costs ten grand could easily be matched in beauty by a lab diamond for a fraction of the price. For couples trying to save for a home deposit, plan a wedding, or just manage the reality of life in Australia right now, lab diamonds open doors that would otherwise stay locked.
I’ve seen customers’ shoulders physically relax when they realise that, yes, they can get the 1.5-carat ring of their dreams — without compromising quality.
2. Ethics Matter More Than Ever
Australians are pretty switched on these days. People want to know where their products come from, what they’re made of, and how they impact the world.
Lab grown diamonds naturally appeal to anyone who wants a clearer supply chain, less environmental disturbance, and transparency from start to finish. As a jeweller, I appreciate that clarity too — it’s refreshing not to dance around vague terminology or outdated mining narratives.
3. Customisation Has Become a Lifestyle Expectation
Here’s something I’ve learned about modern buyers: they don’t want to settle. They don’t want the “closest thing on the shelf.” They want the ring they’ve envisioned — down to the curve of the band and the exact height of the setting.
And because lab diamonds cost less per carat, people suddenly have the freedom to choose shapes or sizes they might not have considered before. Pear cuts, elongated cushions, east-west emeralds — I’ve crafted them all for customers who would’ve stayed firmly in the 0.7-carat range if they’d gone for natural stones.
With online platforms now offering intuitive custom ring builders, it’s never been easier for buyers to explore designs. A lot of my clients actually begin their search by browsing options to buy lab grown diamonds so they can compare shapes, clarity, and sparkle before stepping into a store.
4. The Social Stigma Is Gone
Honestly, maybe five years ago, people were still whispering, “Will anyone be able to tell?” These days? Not even a hint of embarrassment. Lab diamonds are featured in high-fashion magazines, worn by celebrities, and recommended by jewellers.
I’ve set lab diamonds for surgeons, teachers, FIFO workers, young couples, retirees — you name it. Every type of buyer is in the mix now.
So… Are Man Made Diamonds Really Worth Buying?
As someone who works closely with both lab and mined stones, I can say this: yes, they’re absolutely worth buying — if they fit your values, lifestyle, and budget.
Let me break it down:
✔ Value for money:
You often get a larger, more brilliant diamond for the same price.
✔ Quality consistency:
The technology behind growing diamonds is incredibly advanced now. That means fewer surprises, more control, and more reliability.
✔ Environmental and ethical appeal:
For many Australians, this is a major selling point.
✔ They look stunning — full stop:
I’ve yet to meet anyone who bought a lab diamond and later regretted the sparkle.
✔ Long-term durability:
Just like mined diamonds, they’re forever stones — the kind you’ll pass down.
A Quick Reality Check: What Lab Diamonds Aren’t
I don’t believe in sugar-coating anything — it’s not how I operate in my workshop, and it’s not how I talk to customers. So let’s clear up a few things.
They’re not a great speculative investment
If you’re buying a diamond to store wealth or as an asset (which most people probably shouldn’t do anyway), lab diamonds aren’t ideal. Their resale value is lower because supply is controlled by technology, not geology.
But honestly? Most people buy diamonds to celebrate something meaningful, not to resell. And in those cases, lab diamonds tick every important box.
They’re not “cheap knockoffs”
This misconception lingers in old-school circles, but professionally speaking, it’s simply wrong. A lab diamond can be graded by GIA or IGI, just like a natural stone, and is measured by the same standards.
They’re not cubic zirconia or moissanite
I still hear this occasionally, and it always makes me chuckle. Man made diamonds aren’t imitation stones — they’re the real deal.
If you want to dive deeper into the differences, there’s a thoughtful exploration of man made diamonds that’s worth reading.
The Buying Experience: How It Actually Feels
I’ve helped customers buy jewellery for every imaginable occasion. And the shift in emotion during the buying process is actually one of the biggest perks of choosing a lab diamond.
People come in nervous, worrying they’ll be forced to compromise. Then they realise they can select a diamond with a clarity grade they genuinely love, not just tolerate. They get excited. They start playing with ring designs they didn’t think they could afford. The whole process becomes joyful rather than stressful.
I once worked with a young couple — both nurses — who came in assuming they’d need to “stick to something simple.” When they discovered the price difference between mined and lab stones, the fiancée started tearing up. Not because she wanted something flashy, but because she suddenly had options she didn’t think were available to her.
That moment stuck with me. Jewellery shouldn’t feel like a financial test. It should feel like a celebration.
Tips From a Jeweller: How to Choose the Right Lab Diamond
If you’re leaning toward a lab grown gem, here are a few insider pointers:
1. Prioritise cut over everything else
A beautifully cut diamond — lab or mined — will outshine a poorly cut bigger stone every day of the week.
2. Ask about fluorescence
It’s not a bad thing, but it can affect how a diamond looks in certain lighting.
3. Don’t obsess over flawless clarity
Even VVS stones often look identical to VS under the naked eye.
4. Choose a reputable retailer
Whether online or in-store, you want someone with proper certifications and transparent grading.
5. Make sure the setting suits your lifestyle
If you’re rough on your hands (tradies, nurses, personal trainers — I’m looking at you), choose a setting that protects the stone.
Where Lab Grown Diamonds Are Headed in Australia
As someone who’s watched market trends shift through the years, I genuinely believe we’re witnessing the start of a permanent change. Australians are practical, thoughtful, and increasingly value-driven. Lab diamonds make sense for a lot of people, and the stigma that once held them back has all but vanished.
Jewellers, too, are embracing the technology rather than resisting it — which is probably the biggest sign that this isn’t just a trend. When the people crafting the jewellery change their perspective, it often means the market has evolved for good.
Some industry insiders are even predicting that lab diamonds will become the norm for engagement rings within a decade. I’m not sure I’d go that far, but I can tell you that the demand is real, consistent, and growing every single year.
A Final Thought From the Bench
Choosing a diamond — any diamond — is personal. It’s emotional. It’s tied to milestones you’ll remember for a lifetime. And from my seat, hunched over a workbench with metal shavings stuck to my shirt, I genuinely don’t believe there’s a “right” or “wrong” choice. There’s only the choice that feels meaningful to you.
If you love the romance and rarity of a mined stone, that’s beautiful.
If you love the ethics, innovation, and practicality of a lab diamond, that’s just as beautiful.
