Most of us weren't taught to question where a diamond came from. We were taught that diamonds meant something, and they do. But the conversation around them has quietly shifted, and it's worth paying attention to.
Lab Grown Diamonds have been around for decades, but they've only recently stepped into the spotlight, not because they're new, but because more women are asking better questions about what they buy and why. What goes into it? What it costs, and for whom.
The short answer is this: lab grown diamonds are real diamonds. Same composition, same brilliance, same grading standards. The longer answer is a little more interesting, and it starts with how they're made.
Here's everything you need to know.
What Are Lab grown Diamonds?
Lab grown diamonds also known as lab-created diamonds, are the real deal: diamonds grown in labs rather than mined. But the thing that often comes as a surprise is this: they are chemically, physically and optically the same as naturally occurring diamonds.
The same crystal structure of carbon atoms. The same hardness, a 10 on the Mohs scale, the highest possible rating. The same brilliance and light performance that make diamonds unlike any other gemstone.
The only difference between lab grown diamonds and mined diamonds is origin, not quality, and not how they look when worn.
A gemologist cannot tell the difference between a lab grown and a naturally occurring diamond by eye. Even with a magnifying lens, the differences are subtle and can only be seen with specialised equipment. So, when you wear a lab grown diamond, you are wearing a diamond, no doubt about it.
How Are Lab Grown Diamonds Made?
Every lab diamond begins with a tiny piece of an existing diamond, called a diamond seed. Think of it as the origin point, the starting note of something beautiful.
From there, two primary methods are used:
HPHT (High Pressure-High Temperature)
This process replicates the conditions deep within the Earth's crust. The diamond seed is placed in a chamber and subjected to temperatures of around 1,500°C and pressure of approximately 1.5 million pounds per square inch. Under these intense conditions, carbon atoms bond onto the seed and crystallise into a diamond, in a matter of weeks, rather than millions of years.
CVD (Chemical Vapor Deposition)
CVD is a more recent and widely used method. The seed is placed in a sealed chamber filled with carbon-rich gases. These gases break down, and carbon atoms gradually layer onto the seed, crystallising into a diamond. CVD typically uses lower heat and pressure than HPHT and allows for greater control over the diamond's final quality.
Both methods yield the same result: a genuine diamond, grown from a seed, shaped by science, and finished by skilled craftspeople.
Lab Grown vs. Mined Diamonds: What's Actually Different?
This is the question at the heart of it all. The honest answer is: very little, in terms of the diamond itself.
What's the same:
-
Chemical composition (pure crystalline carbon)
-
Hardness and durability
-
Optical properties: brilliance, fire, and sparkle
-
Grading criteria: lab diamonds are assessed using the same 4Cs (cut, colour, clarity, carat) as mined diamonds
-
Certification: reputable labs like IGI (International Gemological Institute) grade and certify lab grown diamonds with the same rigour
What's different:
-
Origin: one comes from the earth over billions of years; the other is grown in weeks using advanced technology
-
Environmental footprint: lab grown diamonds require significantly less land disruption and carry a lighter ecological impact
-
Price: lab diamonds are typically 70-85% less expensive than comparable mined diamonds, making meaningful pieces far more accessible
-
Availability: mined diamonds are finite and supply-constrained; lab grown diamonds can be produced consistently, making a wider range of sizes and grades accessible to more people
Whether you're marking a moment, celebrating a milestone, or simply because you love beautiful things, a lab grown diamond delivers everything a mined diamond does, for a fraction of the cost.
Are Lab Grown Diamonds Ethical and Sustainable?
This is where it gets interesting. Mining diamonds, although highly regulated in many areas, has often been associated with environmental degradation, excavation, water consumption and greenhouse emissions. The human cost, in certain regions, has also been well-documented.
Laboratory Grown Diamonds avoid many of these issues. They are ethically sourced, there are no mines, no geopolitical sourcing concerns and no issues with provenance. The production process is highly energy-dependent, but increasingly uses renewable energy; the footprint is a fraction of that required for open-pit mining.
For the modern woman, this choice carries meaning. A lab grown diamond reflects a way of thinking that values both beauty and responsibility. As more people begin to see that balance, lab grown diamonds are becoming a natural part of how jewellery is chosen today.
The 4Cs: Here's What to Look For
Whether mined or lab grown, every diamond is evaluated on the same four criteria:
-
Cut: The most important of the 4Cs. A well-cut diamond maximises light reflection, giving it that characteristic sparkle. Poor cut quality dulls even the clearest stone. Always prioritise an excellent or ideal cut.
-
Colour: Diamond colour is graded from D (colourless) to Z (light yellow). For lab grown diamonds, D-F is colourless; G-J is near-colourless and often indistinguishable to the naked eye at a significantly lower price point.
-
Clarity: Refers to internal inclusions and surface blemishes. lab grown diamonds often have fewer natural inclusions than mined ones. VS1 and VS2 clarity is typically the sweet spot, clean to the eye without paying a premium for near-flawlessness.
-
Carat: Simply the weight of the diamond. Because lab grown diamonds are significantly more affordable, you can often choose a higher carat weight within the same budget, something that would simply be out of reach with a mined stone.
Certified Brilliance: Why Certification Matters
Laboratory grown diamonds should always come with a grading certificate from a reputable gemological laboratory. IGI (International Gemological Institute) and SGL (Solitaire Gemological Laboratories) are among the most widely recognised bodies for certifying lab diamonds.
The certificate confirms the diamond's 4Cs, confirms it is lab grown (not a simulant), and gives you full transparency into exactly what you're purchasing.
At Keemti, every diamond we use is certified and conflict-free. We believe you should know exactly what you're wearing, and have documentation that backs it.
How Keemti Brings Lab Grown Diamonds to Life

The Bottom Line
Lab grown diamonds or Laboratory Grown Diamonds should always have a certificate from a gemological laboratory. The International Gemological Institute (IGI) is the most prominent lab diamond certification authority.
The certificate will confirm the 4Cs of the diamond, let you know that the diamond is lab grown (not a simulant), and provide you with complete information on what you are buying.
At Keemti, all our diamonds are certified and conflict-free. We want you to know exactly what you're wearing, and have proof of that.
A Diamond for Every Chapter of Yours
Here's what we know about the woman who wears Keemti: she doesn't wait to be celebrated. She marks her own moments, in her own time, in her own way.
Maybe you're at the start of something, a new role, a new city, a new chapter you're quietly terrified about. Maybe you've just made it through something hard, and no one else quite knows how much that cost you.
Or maybe everything is simply, beautifully good, and you want something on your wrist or around your neck that holds that feeling close. A lab grown diamond doesn't shine any less because it was grown in a lab. And your moment doesn't matter any less because the world didn't witness it.
At Keemti, we make jewellery for both the seen and the unseen, the loud wins and the quiet ones. Because you are worth celebrating. Exactly as you are. Exactly now.
