About our Creation Process

This is not ‘push button’ technology; it requires constant crafting and fine-tuning by our resident engineers and alchemists on site at our facilities in Gloucestershire, England.

Our carbon is harvested from the atmosphere and held forever in a diamond, and our water is captured rain from the Cotswolds countryside.  Wind and sun provide our energy: the entire process powered with our own renewables provided by our sister company, Ecotricity. 

This is innovation working in harmony with Mother Nature for a more brilliant tomorrow.

Step by Step

Our British made diamonds are like no other. Everything we need to create our diamonds comes from the sky, including 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 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 training and paying the female artisans the same as their male counterparts, and giving them flexible working hours to work accommodate family commitments.

  • Step 5.

    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.
