They sparkle like mined diamonds because… they are diamonds.
Let’s clear the air right away:
lab-grown diamonds
aren’t fakes, aren’t dupes, and definitely aren’t cubic zirconia’s cooler cousin. They’re not moissanites. They’re not “American diamonds.” They are chemically, physically, and optically identical to mined diamonds. The only difference? Their origin story.
So, what exactly is a lab-grown diamond?
It’s pure carbon, crystallised into the same atomic structure as a mined diamond - only above ground, thanks to cutting-edge science. Put them side by side and even expert gemologists need specialised equipment to tell the difference.
And here’s the clincher:
lab-grown diamonds are
certified by IGI
(International Gemological Institute) on the exact same parameters as mined diamonds
- cut, colour, clarity, and carat. The famous 4Cs apply equally. Same sparkle, same permanence, same prestige.
How Do You Grow a Diamond?
With patience, precision, and a little science magic. There are two main ways:
HPHT (High Pressure, High Temperature):
This method mirrors nature perfectly - extreme heat and pressure compress carbon into diamond, just as it happens underground, only much faster. At Coluxe, we choose HPHT because it delivers
exceptional brilliance
,
consistency
, and
durability
.
CVD (Chemical Vapour Deposition):
Another advanced method where carbon-rich gases create diamonds layer by layer.
Both methods create real diamonds
. Both are certified and graded just like mined. At Coluxe, we only work with
transparent
,
ethical growers
who meet our quality obsession.
Will Anyone Know the Difference?
No. Not at dinner. Not in the boardroom. Not even at a jewellery counter. The only way to distinguish a lab-grown from a mined diamond is with advanced lab equipment. To the eye - and even under a jeweller’s loupe - they’re identical. The sparkle, the strength, the fire: all the same.
Why Are They More Affordable?
Here’s the honest answer: mined diamond pricing has always been about scarcity and marketing. Lab-grown skips the billion years and the mining, so costs are driven by technology, not geology. That’s why a
lab-grown diamond
can cost up to 10x less
than a mined stone of the same size and quality.
And here’s the fun part: that means you can choose a bigger diamond, higher clarity, or even a coloured gemstone - without compromise. It's a
smarter luxury
.
Will They Hold Resale Value?
This is the most common question. Jewellery isn’t the stock market - it’s about joy, not speculation.
That’s why Coluxe offers a
lifetime buyback policy
. You’ll always have the option to trade in, upgrade, or reset your piece with us. And meanwhile, you get to live in your jewellery every single day - not keep it locked away like an “investment.”
Are They Durable Enough for Daily Wear?
Yes. Lab-grown diamonds are the same hardness (
10 on the Mohs scale
) as mined diamonds. That means they’re just as tough, just as enduring, and perfect for everyday studs, solitaire rings, or stacks of eternity bands.
Are They Really Sustainable?
Fair question. Lab-grown uses energy, yes - but it doesn’t move mountains, destroy ecosystems, or fuel conflict zones. No scars on the Earth. No murky supply chains. Many HPHT growers are already moving toward renewable energy, making the footprint lighter every year.
Net-net: lab-grown is significantly
kinder to the planet and to people
.
What About Coloured Stones?
Good news
: emeralds, rubies, and sapphires can also be lab-grown - with the same atomic structure, the same brilliance, the same rich hues. They look
identical
to mined gemstones (unless you enjoy carrying a microscope in your clutch). And like diamonds, they’re
certified
,
cleaner
, and more
consistent
in quality. That’s why
Coluxe plays in colour
as joyfully as we do in diamonds.
Will People Judge Me For Choosing Lab-Grown?
Some still think “real” means mined. We disagree. To us,
real
means conscious, modern, and yours by choice. Lab-grown isn’t about compromise. It’s about
evolution
. It’s the next chapter of luxury - bold, intentional, and smarter.
Can I Insure a Lab-Grown Diamond?
Absolutely. Lab-grown diamonds are insurable on the same basis as mined, using IGI certification and valuation.
How Do I Care For Them?
Just like how you would do for the mined. A soft brush, mild soap, and a little care will keep them sparkling. At Coluxe, we also offer after-sales care and polishing, because fine jewellery deserves to live on your skin, not in a locker.
The Coluxe Point of View
We didn’t start Coluxe to follow a trend. We started because we believe diamonds shouldn’t come with gatekeeping -
financial
,
emotional
, or
environmental
.
Lab-grown diamonds open the door to a new kind of luxury:
expressive, accessible, joyful.
They let you buy your own ring without waiting for permission. They let you explore colour without guilt. They make
fine jewellery, an
everyday experience
, not a rare occasion. Because jewellery should feel good - and be good. That’s the point.

Frequently Asked Questions (FAQs)
1. What exactly are lab-grown diamonds?
Lab-grown diamonds are real diamonds with the same chemical, physical, and optical properties as mined diamonds. The difference lies in origin: they are created above ground using HPHT or CVD methods. They are IGI-certified, stunningly brilliant, and perfect for everyday wear.
2. Are lab-grown diamonds durable enough for daily use?
Yes. Lab-grown diamonds score 10 on the Mohs hardness scale, just like mined diamonds. This makes them ideal for studs, solitaire rings, bracelets, and stacked jewellery that you can wear every day without worry.
3. How are lab-grown diamonds more sustainable than mined diamonds?
Lab-grown diamonds avoid mining’s environmental and ethical impacts. They’re created in controlled facilities, often with renewable energy, making them a cleaner, more conscious choice without compromising beauty or brilliance.
4. Can coloured gemstones be lab-grown too?
Absolutely. Emeralds, rubies, and sapphires can also be lab-grown, offering rich hues, consistent quality, and ethical sourcing. They let you enjoy vibrant gemstones for everyday styling without the environmental cost of mined stones.
5. How can I tell a lab-grown diamond from a mined diamond?
To the naked eye - or even under a jeweller’s loupe - lab-grown and mined diamonds are indistinguishable. Only advanced lab equipment can tell them apart, so you get all the sparkle and prestige without compromise.
