How Lab Grown Diamonds Are Made – Inside the Process

💎 How Lab Grown Diamonds Are Made – Inside the Process

If you’ve ever asked:

“How can diamonds be grown in a lab?”
“Are they even real?”
“What’s the difference between HPHT and CVD?”

You’re not alone — and you’re about to find out.

Let’s break down the science behind lab grown diamonds, and why they’re changing the way we buy fine jewelry.

🧪 First: Are Lab Diamonds Real?

Yes — lab grown diamonds are 100% real diamonds.

They’re not simulants like cubic zirconia.
They’re not synthetic fakes.
They are chemically, physically, and optically identical to mined diamonds.

The only difference?
They’re made above the earth, not dug from below it.

🔬 The Two Main Methods of Diamond Growth

There are two main technologies used to grow diamonds in labs:

1️⃣ HPHT – High Pressure High Temperature

This method mimics the earth’s natural process of creating diamonds.

  • A small diamond seed is placed in carbon

  • The machine applies extreme pressure and heat (like underground conditions)

  • Carbon crystallizes around the seed, forming a full diamond

HPHT diamonds are often used to enhance color, like D–F grade white diamonds.

2️⃣ CVD – Chemical Vapor Deposition

This is the newer, more precise method.

  • A diamond seed is placed in a vacuum chamber

  • A carbon-rich gas (like methane) is added

  • Microwaves heat the gas, breaking it into carbon atoms

  • These atoms bond to the seed, growing layer by layer into a diamond

CVD diamonds are known for their clarity and stability. Most of Nuit D’or’s lab diamonds are grown this way.

💡 So, Which One Is Better?

Both HPHT and CVD create beautiful, certified diamonds.
The right choice depends on the diamond’s:

  • Size

  • Shape

  • Clarity goals

  • Color preferences

At Nuit D’or, we use both methods, depending on what produces the best result for each design.

📜 Are Lab Diamonds Certified?

Yes — every lab grown diamond we use is:

✅ Certified by GIA or IGI
✅ Graded for cut, clarity, color, and carat
✅ Laser-inscribed with a serial number (just like mined diamonds)

We proudly provide certification with every high-value purchase.

🌍 Why This Process Matters

By growing diamonds in labs, we reduce:

  • Mining waste

  • Water pollution

  • Human rights issues

You get an ethically clean diamond — without sacrificing beauty or brilliance.

💎 It’s sparkle you can feel good about.

✨ The Future Is Lab Grown

As technology improves and shoppers get smarter, more people are choosing cultured, conflict-free diamonds.

From engagement rings to earrings, lab grown jewelry is no longer a trend — it’s the future of luxury.
