Lab Grown Diamonds

What are lab-grown diamonds and how are they made?

If diamonds are formed over billions of years deep inside the Earth, why does so much of what we buy today still rely on chance, scarcity, and extraction? And what happens when science offers a more precise way?

Lab-grown diamonds are real diamonds, made of pure carbon with the same crystal structure, hardness, and optical properties as mined diamonds. The difference lies not in the diamond itself, but in how much control exists over the outcome.

How lab grown diamonds are created

Lab-grown diamonds start with a small diamond seed and grow under conditions that mirror and improve upon nature's process.

HPHT (High Pressure, High Temperature) Method:

  • Replicates the intense pressure and heat found deep within the Earth
  • Carbon crystallises around the seed
  • Produces diamonds with strong structural integrity

CVD (Chemical Vapour Deposition) Method:

  • Uses a carbon-rich gas broken down at the molecular level
  • Carbon atoms build up gradually, layer by layer
  • Allows precise control over clarity, colour, and growth consistency

Both methods produce diamonds that are chemically and optically identical to mined diamonds — without depending on unpredictable geological conditions or destructive extraction.

Precision vs Chance

Mined diamonds are shaped by millions of years of natural randomness. Their inclusions, colour variations, and asymmetry are accepted as “natural character” because there is no way to refine the process once the stone is formed.

Lab-grown diamonds are shaped by intent.

  • Higher average clarity
  • More consistent cut and symmetry
  • Better light performance and brilliance
  • Larger sizes available without compromising quality

When a diamond can be grown deliberately rather than discovered accidentally, the results speak for themselves.

At Aukera, this difference matters. We work with lab-grown diamonds chosen for exceptional brilliance and balance, ensuring that what reaches the customer is not just real, but remarkably well made.

Common myths about lab grown diamonds (and the reality)

“Lab-grown diamonds aren’t real.”

They are real diamonds. This myth survives largely because the traditional diamond industry has spent decades protecting scarcity.

“They won’t last.”

Durability is identical. Carbon is carbon.

“They’re inferior.”

What’s commonly available in the mined diamond market today often falls below the clarity and cut standards routinely achieved in high-quality lab-grown diamonds.

“All lab-grown diamonds are the same.”

They aren’t. Growth method, cutting expertise, and quality control make a decisive difference.

Why the shift to lab grown diamonds is inevitable

Modern buyers are asking different questions:

  • Why pay more for lower clarity?
  • Why accept environmental destruction as a given?
  • Why celebrate rarity born from chance, when precision delivers better outcomes?

Lab-grown diamonds answer these questions clearly — offering better quality, better value, greater design freedom, and a clean, ethical origin.

Aukera works exclusively with lab-grown diamonds that meet the highest benchmarks of brilliance, certification, and craftsmanship. When science replaces uncertainty and ethics replace compromise, the result isn’t just a new kind of diamond — it’s a more evolved one.
