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.

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

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.

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.

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.

Official Diamond Certification using the expected 4C's is conducted at Anchorcert, UK - we don't accept any stones under H VVS2. These hand selected stones are then set made into our fine jewellery pieces in recycled precious metals. All that remains is to brighten up the lives of our customers, who know they are wearing something beautiful from both inside and out.
