The Difference

SkyDiamond Difference

All diamonds, whether formed naturally and then mined from the Earth or created by science, are composed of carbon. In nature, diamonds form over billions of years under extreme conditions of high temperature and pressure. Laboratory-grown diamonds are created using technological processes that replicate these conditions to form a chemically identical diamond, equally composed of pure carbon in the same crystalline structure, which gives diamonds their characteristic hardness and brilliance.

Born different

A SkyDiamond is not mass produced, it is born brilliant. Every SkyDiamond is a promise of responsibility-composed from the air that we breath and the rain from our skies. Each is humanely crafted, and carries the SkyDiamond guarantee that your jewel is untainted by conflict and the impact of smoke spewing, coal-lab-factories.

ETHICAL BRILLIANCE
In today's market, we are all increasingly conscious of the origins and ethical implications of our purchases especially in an area so contentious as diamonds. Ethically sourced diamonds that are conflict-free and sustainably produced hold significant value to those who protect our future.
ETHEREAL ORIGIN
With each facet meticulously cut by female owned lapidarists, every Sky Diamond embodies the ethereal beauty of the skies from which they were born - a symphony of light and luxury, reserved for the most discerning admirers of the sublime. With no earth destroyed, no person harmed and zero coal burned.
ELITE PROVENANCE
The exceptional purity of a diamond is not only a testament to its quality but also to its brilliance and aesthetic appeal. Our clients look for diamonds that embody perfection and stand out for their clarity and intrinsic beauty. Never mass produced, every diamond is set by hand, here in the U.K.

Impact Report Findings

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

The Real Thing
The manufacturing of Skydiamond replicates the earth’s process for mined diamonds, making them structurally and chemically identical.
99.79% Reduced Emissions
For every carat of Skydiamond produced, greenhouse gas emissions reduce by 99.79% compared to mined diamonds.
Negative Emissions
Compared to both mined and lab-grown diamonds, the Skydiamond process is the only one with negative emissions. This is due to the use of 100% renewable electricity, direct air capture for CO2, and hydrogen production from the electrolysis of 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.
Significantly Reduced Emissions
Lab-grown diamonds also avoid all the sulphur oxide, and more than half the nitrous oxide emissions associated with mined diamonds.
Decarbonised at Every Stage of Creation
Skydiamond has a considerably larger avoided carbon footprint, in addition to avoiding pollution of the land and water too.

Our Creation Process

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 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.
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.
