Lily Cole X Skydiamond


Supermodel, actor and environmental activist co-designed a statement collection to create a moment of conversation and reflection.

“People like buying and wearing jewellery; they have done so for thousands of years. So how do we make jewellery without it costing us the world? Is there a way to design products so they give back in the process?

These are the questions Dale [Vince] sought to ask and answer in founding Skydiamond, and it’s beautiful to see them realised."

"What do we take and what do we give when we make things?

We must never forget we are entangled with the planet."

What Makes A Lab-Grown Diamond?

There are many names for conventional laboratory grown diamonds: 'man-made', 'created', 'above-ground' or 'synthetic'. They are created by replicating similar high-pressure, high-temperature conditions as mined diamonds. A selected diamond 'seed' experiences these conditions in a lab, crystallising into a rough lab-grown diamond after several weeks. The rough jewel is then cut and polished, resulting in a stone with the same chemical and optical properties as mined diamonds.

Are All Lab-grown Diamonds Created Equally?

No, they are not. Whilst a Skydiamond is technically also a lab-grown diamond, it leads a new wave in man-made diamond creation due to a first-of-its-kind, patent-pending production process, and end-to-end traceability. Skydiamonds are completely clean, created with raw materials exclusively from the sky; C02, Wind, sun and rain. The renewable energy is powered by our sister company Ecotricity, and this informs their carbon-negative status, setting them apart from other lab-grown diamonds in terms of composition, characteristics, and emissions footprint, creating incredibly beautiful stones ordained by nature.

What Is A Natural Diamond?

Diamonds, the toughest natural substance on Earth, originate from carbon through a naturally occurring underground process taking between one to three billion years. Formed at depths miles beneath the Earth's mantle, they are created under extreme conditions of high pressure and temperature. Following their creation, diamonds travel to the surface through molten rock and are mined and extracted. While natural diamonds are cherished for their beauty, the mining process does carry significant environmental and social impact, with often hard-to-monitor working conditions, leading to loss of habitat for wildlife, deforestation, soil erosion, and water pollution. That’s why we are now seeing a growth in popularity when it comes to man-made alternatives.

What Is Traceability In This Context?

Skydiamond traceability ensures a 100% transparent journey. All stones over 0.5 carats through the meticulous process of AnchorCert certification (see further below). Each diamond over 0.5cts is engraved with ‘SKYDIAMOND’ and a unique code, with an accompanying report and product breakdown. This code becomes an indelible and infinite link between a stone and its origins – We never want to be mistaken for a land-mined diamond.

What Is AnchorCert, And What Guarantee Does It Give?

AnchorCert is a best-in-class, UK-based gemmological laboratory conducting rigorous assessments and certifications for gemstones; the British equivalent to the Gemmological Institute of America (GIA). Their 360 degree process guarantees the gem has undergone thorough examination and testing by AnchorCert experts, to assure the diamond's authenticity, quality, and adherence to specified standards, instilling confidence in its value and characteristics.

Where On The Universal Diamond Grading System Does Skydiamond Sit?

We adhere to the industry’s leading recognised system of diamond quality, the 4Cs, which represent the universal grading system for all diamonds. The official, industry-standard colour grading scale as defined by the Gemmological Institute of America (GIA).  80% of the Skydiamonds we create are between D Flawless and H VS2.
