Grown in a lab. 100% diamond.

Real diamonds, grown with brilliance and responsibility — chemically, physically and optically identical to mined diamonds, and beautifully more affordable.

  • Pure carbon
  • Hardness 10
  • IGI & GIA certified
  • Conflict-free
What are they

Identical to nature, kinder to the planet.

Lab grown diamonds are genuine diamonds, created with technology that recreates the exact conditions in which diamonds form deep inside the earth. The result is chemically, physically and optically identical to a mined diamond.

Because they're grown in controlled environments, C6 lab grown diamonds are conflict-free, environmentally responsible and available in a wide range of colours, shapes and sizes — with the same fire and brilliance as natural diamonds, often at a fraction of the price.

How they're made

Two paths to brilliance.

Every C6 lab grown diamond begins as a tiny diamond seed and is grown with one of two advanced methods.

Chemical Vapour Deposition

Built atom by atom.

A diamond seed sits inside a sealed chamber filled with carbon-rich gas. When energised, the gas breaks down and pure carbon settles onto the seed, layer by layer, over several weeks.

  1. Seed plate placed in a vacuum chamberA thin slice of diamond is the starting point.
  2. Gas heated into a plasmaMethane and hydrogen are energised with microwaves.
  3. Carbon builds up on the seedThe crystal grows slowly, with remarkable purity.
  4. Cut, polished & certifiedExactly like a mined rough diamond.

Good to know: both methods produce real diamonds. When choosing a stone, the cut and the 4 C's matter far more than how it was grown.

Know the difference

Lab grown vs mined vs simulants.

A lab grown diamond is a true diamond. Simulants like cubic zirconia and moissanite only imitate the look.

Quality explained

The 4 C's, made simple.

Every C6 lab grown diamond is graded on the same four characteristics as a mined diamond.

Cut

How well the facets are shaped and angled — the biggest factor in sparkle.

Excellent → Poor

Color

Graded from D (colourless) down the alphabet as a faint tint appears.

D → Z

Clarity

How few tiny inclusions the stone has when viewed under 10× magnification.

FL → I3

Carat

The weight of the diamond. With lab grown, more carat for the same budget.

Why choose lab grown

Luxury with a conscience.

Ethical & conflict-free

Grown in transparent, controlled environments — never linked to conflict mining.

A responsible choice

No large-scale land disruption, and a smaller footprint than traditional mining.

Exceptional value

A bigger, brighter diamond for your budget than an equivalent mined stone.

Identical brilliance

The same hardness, fire and sparkle — indistinguishable to the naked eye.

Certified · guaranteed · trusted

Every stone comes with its papers.

Each C6 lab grown diamond is independently graded by leading gemological laboratories and laser-inscribed with a unique report number — so its quality is verified, and yours forever.

Yes. A lab grown diamond is made of the same pure carbon crystal as a mined diamond, with the same hardness, fire and brilliance. Only its origin is different — it is grown in a lab instead of mined from the earth.

Not by eye or with a standard diamond tester. Only specialised lab equipment can identify the growth method — which is why every C6 diamond comes with a certificate that clearly states it is lab grown.

No. A lab grown diamond is a real diamond, so it is just as stable and durable. With normal care and cleaning it will keep its sparkle for generations.

Yes. Our diamonds are independently graded by leading labs such as IGI and GIA, and the certificate number is laser-inscribed on the girdle so you can always match stone to report.

They are two ways of growing the same diamond. HPHT recreates the earth's heat and pressure; CVD builds the crystal atom by atom from a carbon-rich gas. Both produce real diamonds — the cut and the 4 C's matter far more than the method.

Lab grown diamonds are best bought for their beauty and value today rather than as an investment. Like most jewellery, resale prices are usually well below the purchase price — the saving comes up front, when you buy.
