Redefining our Future

At Skydiamond, we believe there is a better way to experience luxury. A way that’s purposeful, planet-positive and uncompromising in beauty. Our jewellery is crafted in Britain using the world’s only carbon-negative diamonds – made not mined, created from the sky in harmony with nature. Every Skydiamond is a story of science and innovation, not extraction– modern alchemy at its finest. It’s love without harm; a symbol of meaningful change that honours the planet and reflects your individual style. Because the future of luxury is not defined by what you wear – it's about what you stand for.

Here are the four sustainability pillars guiding our mission

Diamond brilliance without destruction

We set out to create the world’s most sustainable diamond, and we’ve done it. Verified by Imperial College London, every Skydiamond is not only carbon-negative but proven to have a better environmental impact than any mined alternative. Made in Britain using only nature’s elements– captured carbon, rainwater, wind and sun – our lab-grown diamonds show that sustainable luxury and cutting-edge design can exist together. They meet the same standards of quality and grading as any mined stone – without the destruction.

Clean Craftsmanship

True craftsmanship should be as ethical as it is beautiful. That’s why every Skydiamond is designed and created in Britain, with complete transparency across our supply chain. Our diamonds travel to just one trusted partner in India beyond our Sky Lab, which meets the highest standards of social and environmental responsibility. We’re also working towards sourcing 100% of our precious metals right here in the UK, with fully traceable, recycled origins. Skydiamond paves the way for sustainable jewellery brands, showing that luxury can be made with integrity.

Circular by Nature

At Skydiamond, circularity isn’tan afterthought – it’s how we operateright from the start. We’re moving beyond the outdated take-make-waste model to create a future where circular economy jewellery is the norm. From design to sourcing to every partner we choose; we’re constantly finding new ways to close the loop. Our jewellery is crafted to last, using diamonds made from surplus carbon from the atmosphere and materials that have been given a second life, without extracting new resources from the earth. From repurposed gold to recycled precious metals rescued from pottery and X-ray waste, our jewellery showcases innovation, where beauty never expires.

"Sustainability isn’t an add-on for us — it’s the blueprint for how we work, how we create, and how we lead. At Skydiamond, we’re proving that beauty, responsibility, and innovation can — and should — exist together."
