Are Lab Grown Diamonds Real Diamonds? The Definitive Answer

13 May 2026 · 8 min read

You've found the one, the piece that made you pause mid-scroll, the kind you save to your phone and keep going back to. And then, almost immediately, a question creeps in. Are lab grown diamonds real?

It's one of the most searched questions in the world of fine jewellery today, and it's a fair one. After all, you're not just spending money, you're marking something. A moment. A version of yourself you've worked hard to become.

Whether it's your first piece of real diamond jewellery, a promise you're making to someone you love, or simply a gift to yourself because you've earned it, the diamond at the centre of it all needs to mean something true.

So here's the answer, clearly and without hesitation, to the question, "Are lab grown diamonds real?” Yes. Lab grown diamonds are real diamonds. Not a version of diamonds. Not an alternative to diamonds. Diamonds, chemically, physically, and optically, in every sense of the word.

Here's everything you need to know.

What Makes a Diamond "Real"?

A diamond, by definition, is a mineral made entirely of carbon atoms arranged in a crystal structure called a diamond cubic lattice. This specific arrangement is what gives diamonds their extraordinary hardness, their refractive brilliance, and their lasting durability.

Lab grown diamonds share this exact same atomic structure. They are graded by the same 4 Cs: cut, colour, clarity, and carat, using the same global standards applied to mined diamonds. This is why the answer to lab diamonds real remains consistent across gemological institutions.

Gemological institutions like the IGI (International Gemological Institute) certify lab diamonds with the same rigour and methodology they apply to earth-mined stones.

So when we say lab grown diamonds are real, we mean it in every measurable sense: same chemistry, same structure, same appearance, same durability.

How Are Lab Grown Diamonds Made?

Every Keemti diamond begins with a seed, a tiny fragment of diamond crystal. From that seed, a full diamond grows under carefully controlled conditions that replicate what happens naturally inside the Earth's mantle, only in a matter of weeks rather than billions of years.

There are two primary methods used to grow lab diamonds:

  • CVD (Chemical Vapour Deposition): A carbon-rich gas is introduced into a controlled chamber, where it breaks down, and the carbon atoms crystallise onto the diamond seed, layer by layer, building a full diamond over time.

  • HPHT (High Pressure, High Temperature): Carbon material is placed under intense heat and pressure, dissolving and then recrystallising around the diamond seed, closely mirroring the conditions deep within the Earth.

Both processes yield diamonds that are chemically and structurally identical to mined diamonds. The origin is different. The diamond itself is not, reinforcing again that lab-created diamonds are real is not a claim, but a fact.


Do Lab Grown Diamonds Pass a Diamond Tester?

Yes, and this is one of the most asked questions for good reason, often phrased as " Do lab diamonds pass the diamond tester?” A standard diamond tester measures a stone's thermal conductivity.

Because lab diamonds have the exact same physical properties as mined diamonds, they pass a diamond tester the same way a mined diamond would. So if you're asking this question, if Lab grown diamonds pass a tester, the answer is yes, without exception.

The only way to distinguish a Lab grown diamond from a mined one is through highly specialised gemological equipment that can detect trace elements and growth patterns invisible to the naked eye. Even trained gemologists cannot tell them apart visually.

This means the diamond in your Keemti piece, whether it's catching light across your wrist during a meeting or held close to your chest in a pendant, carries every quality that makes a diamond a diamond.


Lab Grown Diamonds vs. Moissanite

This is where the conversation needs some clarity, especially when people search for "are Lab grown diamonds fake?" lab grown diamonds are not diamond simulants. This distinction matters.

Diamond simulants, like cubic zirconia or moissanite, are stones engineered to look like diamonds but are made of entirely different materials. Cubic zirconia is a synthetic oxide; moissanite is silicon carbide.

Neither shares diamond's chemical makeup. Both look and behave differently over time; cubic zirconia can cloud and scratch more easily, and moissanite produces a very different kind of sparkle, often described as more rainbow-like and less crisp than a diamond.

A ab grown diamond is not mimicking a diamond. It is a diamond. Same hardness (10 on the Mohs scale), same refractive index, and in many cases, even greater brilliance. 

Because Lab grown diamonds are formed in controlled environments, no gases get trapped within the crystal structure during growth. In natural diamonds, those trapped particles can interrupt light passage. Without them, a Lab grown diamond often returns light more cleanly and brightly. That's not a selling point, it's simply what the science shows.

When you wear a Keemti piece, you carry something that was built with intention, grown with precision, and chosen for you, a real diamond, in every sense of the word. 

Why Lab Grown Diamonds Make Sense Right Now

The case for Lab grown diamonds isn't just scientific. It's personal, practical, and intentional, especially when considering whether Lab grown diamonds are real in the context of modern choices.

  • Ethically crafted: Every Lab grown diamond is conflict-free. There are no compromised supply chains, no murky origins. You know exactly where your diamond came from and how it was made.

  • Planet-conscious: Lab grown diamonds require significantly less land use than mined diamonds. Diamond mining involves vast excavation, while a diamond laboratory operates in a comparatively compact space with no large-scale ecological disruption. Technology continues to advance, with many labs now producing diamonds using renewable energy sources.

  • Accessible luxury: A Lab grown diamond typically costs significantly less than a mined diamond of the same cut, colour, and clarity. This doesn't make it less valuable; it makes it more accessible. At Keemti, we believe premium design and genuine quality shouldn't come with an unreachable price tag.

Certified, Graded, and Verified

Every Keemti diamond comes certified. Certification from institutions like the IGI means your diamond has been independently evaluated and graded for its cut, colour, clarity, and carat weight.

The certification number is laser-inscribed on the girdle of the diamond, visible under magnification, so you always have transparent proof of what you own.

Certification is not just a formality. It's your assurance that the diamond was created, assessed, and verified to global standards, reinforcing again that lab diamonds are real and backed by measurable proof.

The Keemti Collections: Diamonds Designed for Your Journey

Understanding that Lab grown diamonds are real changes the way you think about what you can own, and what each piece can mean.

  • The Everyday Edit is designed for the woman who moves between moods and moments with ease. Pieces that work from Monday morning to Saturday evening, diamonds that don't demand an occasion to be worn, because the everyday is its own kind of milestone.

  • The Love Chronicle holds the moments that language can't quite carry. Whether it's a new beginning, a relationship deepening, or simply a love that deserves to be named, these pieces are designed to hold emotion the way memory does, permanently.

  • The Promise Collection is for bonds that don't need explanation. The Promise Ring, with its two paths crossing into one, speaks to commitments made not out of obligation, but out of genuine choice. Some promises are worn, not spoken. This collection is for those.

Each of these collections is set with Lab grown diamonds. Each is designed with intention. And each one answers the question, are Lab grown diamonds real, not just through science, but through meaning.

The Question Behind the Question

When someone questions the authenticity of Lab grown diamonds, they're often asking something deeper: Does it count? Does it hold value? Does it mean something?

The answer is yours to give. But here is what we know: a Keemti diamond is real in every scientific, gemological, and certified sense. It is graded by the same standards, tested by the same tools, and worn with the same pride. The only difference is how it came to be, grown with intention, rather than mined from the earth.

And for the woman who values her choices as much as her achievements, that difference feels less like a compromise and more like an alignment.

You've worked for the things that matter to you. You've built something, a version of yourself that you're still growing into, one step at a time. Your jewellery should reflect that. Not because it proves something to someone else, but because you deserve to wear what is genuinely yours, real, brilliant, and made with purpose.

That's what every Keemti piece is. A real diamond. A real moment. A real you.
