About Skydiamond

The world's most sustainable lab-grown diamond is made from the sky. Skydiamond is where science and nature come together. Created in the UK using only four elements – sun, wind, rain and atmospheric carbon – we’re the first and only certified carbon-negative lab-grown diamond brand. This is modern alchemy at its finest; man working in harmony with nature. 

A symbol of conscious beauty, a Skydiamond embodies the choice to move beyond extraction and into innovation. It carries no environmental cost, no human suffering – just pure, uncompromised brilliance in design and imagination. 

Diamonds made from the sky

We work in harmony with nature to create something truly beautiful, giving people a choice. Not a compromise, but a solution. A way to keep what you love without costing the Earth.

Because you shouldn't have to stop celebrating beauty to protect the planet.

You just need a better way to do it.

Relentless innovation

Not all lab-grown diamonds are created equal and our Sky Lab in Gloucestershire proves it every day. It is the only facility in the world producing lab-grown diamonds locally and exclusively from nature’s elements, ensuring end-to-end traceability. Powered by 100% renewable energy from our sister company Ecotricity, each Skydiamond is truly clean – from composition to creation. 

Working with Icons

Skydiamond has already partnered with some of the most visionary names in fashion and design – from Stephen Webster to Gucci Vault – and has been worn by our ambassador, the supermodel and environmental advocate Lily Cole.

This sky-high thinking comes from Dale Vince OBE, eco-entrepreneur and founder of Skydiamond, whose portfolio of green innovations is reshaping industries from his base in the Cotswolds, Great Britain.

Our Creation Process

Our diamonds are crafted in Britain and made unlike any other. Everything we need to create them comes from the sky: sun, wind, rain and something the world has too much of: CO₂.

  • Step 1.

    We extract CO₂ from the atmosphere, which we liquify and purify – an important step in ensuring the quality of our diamonds. With the CO₂ removed, the air released back into the atmosphere is cleaner than we found it.

  • Step 2.

    We take rainwater collected from our factory roof and split it into oxygen and hydrogen using electrolysis.

  • Step 3.

    CO₂ from the air and hydrogen from the rain are combined with biological single-cell life forms (the equivalent of a diamond sourdough starter) in a completely patented and bespoke process to create methane, which we feed into our diamond mills - the name for our CVD capsules - with a dash of nitrogen.

  • Step 4.

    Inside our mills we grow our Skydiamonds on tiny diamond seeds (which we also make) in a ball of plasma running at about 1,000 degrees Celsius – roughly the temperature of the outer layer of the sun – using the renewable energy provided by the solar and wind power of our sister company, Ecotricity.

  • Step 5.

    Several weeks later, our Skydiamonds have emerged. They are sent in batches to world class cutters and polishers in India; a woman's collective who train and pay female artisans at the same level as their male counterparts, and give them flexible working hours to accommodate family commitments.

  • Step 6.

    Our diamonds are certified using AnchoCert’s 4Cs for impeccable quality in colour, clarity, cut and carat. These hand selected stones are then set into our fine jewellery pieces in recycled precious metals, ensuring they reflect true beauty and your values.

Impact Report Findings

Skydiamond was born to contribute to a planet conscious future, creating ‘another way’ without compromise on quality or beauty.

We invited independent experts at Imperial College London to conduct a full analysis of our process.

  • 99.79% Reduced Emissions

    For every carat of Skydiamond produced, greenhouse gas emissions are reduced by 99.79% compared to mined diamonds. 

  • Negative Emissions

    Unlike mined or conventional lab-grown diamonds, Skydiamond is the only diamond made with negative emissions.We power our process with 100% renewable energy, capture CO₂ directly from the air, and produce hydrogen through the electrolysis of captured rainwater.

  • Less Waste

    Compared to growing diamonds in a laboratory, mined diamonds produce 4,383 times more waste, use 2.14 times the energy and 6.8 times as much water. 

We’re proud to achieve this through design, without offsetting, creating exceptional products with purpose.

Our Founder, Dale Vince

"Skydiamonds are modern alchemy. I was looking for ways to not just capture carbon from the atmosphere but in a permanent way, and of course, a diamond is the purest form of condensed carbon."
