If you’re searching what is a lab created diamond, let’s cut straight to the answer. A lab created diamond is a real diamond, made in a modern laboratory instead of being pulled out of the earth. It has the exact same sparkle, brilliance, and hardness as a mined diamond, but comes with a more affordable price tag and an ethical backstory.
Over the last decade, these diamonds have exploded in popularity, especially among young couples in the US who care about value and responsibility. Many buyers today want a diamond that looks flawless, feels timeless, and still fits their budget, and that’s where lab grown diamonds shine.
In this complete guide, we’ll explore in detail what is a lab created diamond, how it’s made, what makes it different from natural stones, why more people are choosing it, and how to buy one with confidence.
What is a Lab Created Diamond?
To put it simply, when you ask what is a lab created diamond, the answer is: it’s a diamond created in a controlled laboratory setting instead of being formed over billions of years deep inside the earth. But that doesn’t mean it’s fake. It’s not glass, not moissanite, and not cubic zirconia. It’s the real deal,pure crystallized carbon with the same atomic structure as natural diamonds.
Different names you’ll hear for lab created diamonds include:
-
Lab-grown diamonds
-
Man-made diamonds
-
Cultured diamonds
-
Engineered diamonds
What makes them different from simulants like cubic zirconia or moissanite? Simulants only mimic the sparkle but don’t have the same hardness, brilliance, or composition. Lab created diamonds, on the other hand, are indistinguishable from mined diamonds to the naked eye.
So if you’ve been wondering what is a lab created diamond, think of it as a genuine diamond with a modern origin story.
How Are Lab Created Diamonds Made?
Understanding what is a lab created diamond means looking at how they’re grown. Scientists have developed two main methods to create diamonds in labs, both of which replicate the natural conditions of diamond formation but on a much faster timeline.
High Pressure High Temperature (HPHT) Method
-
A small diamond seed is placed in carbon.
-
The seed is subjected to extremely high pressure and scorching temperatures.
-
Carbon atoms bond and crystallize around the seed, forming a full diamond.
-
This process closely mimics how diamonds form under the earth’s crust.
Chemical Vapor Deposition (CVD) Method
-
A thin slice of diamond seed is placed inside a vacuum chamber.
-
The chamber is filled with carbon-rich gases, which are heated until the carbon atoms break down.
-
These atoms settle on the seed, slowly growing it layer by layer into a complete diamond.
-
This method allows precise control over quality and size.
Both methods produce diamonds that are physically and chemically the same as mined diamonds. The difference is time,what takes nature billions of years can now be done in weeks.
Are Lab Created Diamonds Real Diamonds?
A big question buyers ask is: are they real? The short answer is yes. When you’re asking what is a lab created diamond and whether it’s authentic, here’s the science-backed answer:
-
They are made of 100% pure carbon, just like mined diamonds.
-
They score a 10 on the Mohs scale of hardness, which means they’re just as durable and scratch-resistant.
-
They are certified and graded by top gemological labs such as GIA and IGI, using the exact same standards as natural diamonds.
-
The only difference is the origin: lab versus underground.
This means if you’re wearing a lab diamond, no one, jeweller or otherwise, can tell the difference with the naked eye. Even professional diamond testers will confirm it as a diamond.
Why Choose a Lab Created Diamond?
There are plenty of reasons why shoppers are turning to lab created diamonds. Let’s break it down.
Cost Efficiency
-
Lab created diamonds are usually 30–50% more affordable than mined diamonds.
-
That means you can buy a larger stone or higher quality cut without blowing your budget.
Ethical Sourcing
-
No risk of conflict diamonds or questionable mining practices.
-
You know exactly where your diamond came from, offering peace of mind.
Environmental Impact
-
Mining has long-term consequences like deforestation, soil damage, and water pollution.
-
Lab grown diamonds avoid those destructive practices. While lab production uses energy, the footprint is still significantly lower.
Quality and Purity
-
Lab created diamonds often have fewer inclusions and better clarity.
-
They are available in a wide color range, giving you more options for a clean, brilliant stone.
When weighing what is a lab created diamond against a mined one, these benefits often tip the scale in their favor.
Lab Created vs. Natural Diamonds
If you’re comparing the two, here are the major differences you should know:
-
Price: Lab diamonds are up to half the cost of mined diamonds.
-
Sustainability: Lab diamonds avoid the environmental destruction caused by mining.
-
Quality: Lab created stones are often clearer with fewer inclusions.
-
Rarity: Natural diamonds are ancient and limited; lab diamonds can be grown repeatedly.
-
Resale Value: Mined diamonds tend to hold resale value better, while lab diamonds currently have less resale potential.
When you break down what is a lab created diamond versus a natural one, it comes down to what you value more affordability and ethics, or rarity and tradition.
Do Lab Created Diamonds Hold Value?
Another common question tied to what is a lab created diamond is about value. Financially speaking, lab grown diamonds don’t hold resale value as strongly as mined diamonds. The market for resale is still growing, and since new diamonds can be produced in labs, supply isn’t as limited as natural stones.
But when it comes to sentimental value, lab created diamonds hold just as much meaning. They are perfect for engagement rings, wedding bands, or anniversary gifts. The memories and emotions tied to the stone are what make it priceless.
So yes, the resale market is different, but the true value of a diamond, lab or natural, is in what it represents.
The 4 Cs of Lab Created Diamonds
Just like mined diamonds, lab created ones are judged by the 4 Cs:
-
Cut: This affects how the diamond reflects light and sparkles. Always prioritize cut quality.
-
Color: Graded from D (colorless) to Z (yellowish). Most shoppers go for near-colorless grades like G- I.
-
Clarity: Refers to internal inclusions. Lab diamonds tend to have fewer flaws, offering higher clarity.
-
Carat: The weight of the diamond. Bigger stones cost more, but with lab created diamonds, you can usually afford a larger carat size.
When shopping, remember to always check for certification from GIA or IGI. That way, you know exactly what you’re getting.
Maintenance and Care Tips
Caring for a lab created diamond is just like caring for a natural one.
-
Clean at home with mild soap, warm water, and a soft toothbrush.
-
Avoid using bleach or chlorine, which can damage metal settings.
-
Get your jewelry professionally checked once a year to ensure the prongs and settings are secure.
-
Consider insuring your diamond jewelry to protect against loss or theft.
Conclusion: Should You Buy a Lab Created Diamond?
So, what is a lab created diamond? It’s a genuine diamond made with science instead of geology. It looks the same, sparkles the same, and lasts forever just like mined diamonds.
The big differences are affordability, ethical sourcing, and sustainability. For many buyers in the US, that makes lab created diamonds the smarter, more modern choice, especially for engagement rings and fine jewelry.
