I still remember the first time I held a lab grown diamond in my hand. It was a rainy Tuesday afternoon in Sydney, the kind where you need a coffee just to stay upright, and a jeweller friend of mine — someone who’s been in the trade for decades — said, “Go on, tell me that’s not real.” I squinted, tilted it under the light, and for the life of me, I couldn’t tell the difference. That was the moment I realised something was shifting in the world of fine jewellery.
Today, lab grown diamond engagement rings are no longer just a niche curiosity — they’re becoming the choice of modern couples who value transparency, sustainability, and affordability, without compromising on beauty or sentiment.
But if you’ve never really looked into them, you might be wondering: how do they actually compare to mined diamonds? Are they really the same? And why are so many people — from environmentally conscious millennials to traditional romantics — making the switch?
Let’s dive in.
The Real Difference Between Lab Grown and Mined Diamonds
First off, it’s worth clarifying something that tends to surprise people: lab grown diamonds are 100% real diamonds. Chemically, physically, and optically, they’re identical to mined diamonds. The only difference is where they come from — one from deep within the earth, the other from a controlled lab environment that replicates nature’s own process.
To put it simply, nature took billions of years to form diamonds under immense heat and pressure. Scientists figured out how to do it in a few weeks — without disturbing the planet in the process.
That’s the part I find fascinating. Lab grown diamonds are created using either the HPHT (High Pressure, High Temperature) or CVD (Chemical Vapour Deposition) method. Both mimic the exact conditions found below the Earth’s crust. The result? A gem that’s every bit as dazzling as anything pulled from a mine.
Even gemmologists often need specialised equipment to tell the difference. So when someone asks if a lab grown diamond is “fake,” the short answer is absolutely not.
The Sustainability Story That’s Hard to Ignore
Now, this is where things get interesting — and a bit emotional for some. Traditional diamond mining has long been linked with environmental and ethical concerns: vast land disruption, water pollution, carbon emissions, and, in some regions, questionable labour practices.
Lab grown diamonds, on the other hand, don’t require open-pit mines or displacement of ecosystems. They’re typically made in high-tech facilities powered increasingly by renewable energy sources.
If you care about your carbon footprint — and honestly, most Aussies do these days — the difference can be quite striking. A study by Frost & Sullivan found that lab grown diamonds produce up to 98% less carbon emissions than mined ones.
That doesn’t mean the industry’s perfect. Labs still use energy, and not every producer is equally sustainable. But overall, it’s a massive step toward a cleaner, more transparent jewellery trade.
And that’s something more couples are proud to wear on their ring finger.
Price and Perception: The Honest Conversation
Alright, let’s talk about money — because that’s often where people’s eyebrows go up.
Lab grown diamonds generally cost 30% to 50% less than mined diamonds of the same size and quality. For a lot of couples, that difference can mean the ability to afford a bigger carat, a unique custom setting, or even part of their honeymoon fund.
But it’s not just about getting “more for less.” It’s about shifting values. People are starting to ask: Why spend extra just for a diamond’s origin story, when the sparkle and symbolism are the same?
That said, some traditional jewellers still hold the view that mined diamonds have stronger resale value. It’s true — the resale market for lab grown stones is still developing. But here’s the thing: engagement rings are rarely about investment. They’re about emotion, commitment, and story.
So, if the idea of an ethical, stunning, and affordable diamond feels right for you, it’s probably worth listening to that gut instinct.
Crafting a Ring That Tells Your Story
What’s really exciting about the rise of lab grown diamonds is how it’s opened up creative freedom. Couples can now design one-of-a-kind rings without feeling boxed in by budget or tradition.
You can customise every detail — from the band metal and diamond cut to the setting style. Whether you’re drawn to a minimalist solitaire or a vintage-inspired halo, you can find a design that feels authentically you.

How the Conversation Has Changed
A decade ago, suggesting a lab grown diamond might’ve raised a few sceptical eyebrows. These days? It’s often the other way around.
Brides and grooms are more informed than ever. They want to know where their gems come from, who made them, and what kind of impact their choices have. Transparency has become part of luxury.
Even established jewellers are adapting. Many now offer both mined and lab grown options side by side — not as competition, but as a reflection of customer demand and evolving ethics.
It’s quite similar to what happened with sustainable fashion. Once people understand they can get the same quality, design, and prestige without compromise, the choice becomes obvious.
The Emotional Side of Choosing Lab Grown
There’s something quietly empowering about choosing a ring that reflects your values. I’ve spoken to couples who say their decision felt like a shared statement — a symbol of the future they want to build together.
One couple from Melbourne told me, “We wanted our engagement ring to stand for more than just love — we wanted it to stand for kindness too.” That sentiment really stuck with me.
And beyond the ethics, there’s also the excitement of being part of something new. Lab grown diamonds represent innovation, progress, and the idea that beauty and responsibility don’t have to clash.
A Little Care Goes a Long Way
Of course, once you’ve found the perfect ring, you’ll want to keep it shining for years to come. Lab grown or mined, diamonds benefit from a bit of TLC.
Simple habits — like taking your ring off before doing dishes or applying lotions — can help maintain that signature sparkle. Gentle cleaning with warm soapy water and a soft brush works wonders, too.
If you’d like to learn more about proper maintenance, this guide on lab grown diamonds offers some great practical tips for jewellery care in general.
Because let’s be honest — an engagement ring isn’t just another accessory. It’s a piece of your story.
So, Should You Choose a Lab Grown Diamond Engagement Ring?
At the end of the day, choosing an engagement ring is one of those decisions that’s deeply personal. There’s no single right answer — only what feels true to you.
If you value sustainability, transparency, and the idea of embracing the future without sacrificing tradition, a lab grown diamond engagement ring might just be the perfect fit.
If you’re drawn to the romance of something formed in the earth over millennia, that’s beautiful too. What matters most is that your choice reflects who you are as a couple.
Personally, I find something poetic about lab grown diamonds. They’re proof that love, like science, evolves — that we can create beauty consciously, without taking too much from the world that gave us so much already.
So, whether your dream ring comes from deep underground or a state-of-the-art lab, remember: it’s not the origin of the diamond that makes it precious. It’s the story you attach to it.
