Lesson one

What is a lab grown diamond?

A lab grown diamond is a real diamond. It is made of the same pure carbon, arranged in the same crystal structure, as a diamond taken from the earth. The only difference is where it was formed – in a controlled laboratory instead of deep underground.

C

Same diamond

Chemically, physically and optically the same as a mined diamond – the same hardness, the same fire, the same brilliance.

◆

Grown, not mined

Scientists recreate the heat and pressure of the earth (HPHT) or grow the crystal layer by layer from carbon gas (CVD). Both produce genuine diamond.

4C

Graded the same way

Lab grown diamonds are judged on the same 4Cs – cut, colour, clarity and carat – as any mined diamond.

Why lab grown

Why more people are choosing lab grown

The same sparkle you would get from a mined diamond, with a few clear advantages.

Better value

A lab grown diamond usually costs much less than a mined diamond of similar size and quality.

More for your budget

Choose a bigger stone or a higher grade for the same spend – your choice, made with full information.

Made to last

A diamond is a diamond: 10 on the Mohs hardness scale, made to be worn every day for a lifetime.

Known origin

Grown in a laboratory, with no new mining needed to create your stone.

We educate you first

The 4Cs, explained simply

Before you buy any diamond, these four words decide its beauty and its price. We walk you through every one of them.

Cut

The sparkle

How well the diamond is shaped and polished. A better cut returns more light to your eye – it matters more than anything else for brilliance.

Colour

The whiteness

Graded on a scale from D (colourless) downwards. The less colour, the rarer and brighter the diamond looks.

Clarity

The purity

Tiny natural marks inside or on the stone. Many are invisible to the naked eye – we show you which ones matter and which do not.

Carat

The weight

The weight of the diamond, not its size alone. Two stones of the same carat can look different depending on the cut.

“We just don’t sell diamonds, we educate you first.”

Questions

Lab grown diamond FAQs

Is a lab grown diamond a real diamond?

Yes. It is pure carbon with the same crystal structure as a mined diamond, so it has the same hardness, brilliance and fire. It is not a simulant like cubic zirconia or moissanite.

Will it pass a diamond tester?

Yes. A standard diamond tester identifies a lab grown diamond as diamond. Only specialised laboratory equipment can tell whether a diamond was grown or mined.

Will my lab grown diamond lose its shine?

No. Like any diamond it does not fade or go cloudy. A simple clean now and then keeps it sparkling.

Why does a lab grown diamond cost less?

It is formed in weeks in a laboratory instead of being found and mined from the earth, so the cost of bringing it to you is lower – the diamond itself is the same.
