Sky Lab in the cotswolds creating carbon negative diamonds

Clear Air Day 20th June: Turning Air Into Lab Diamonds

At Skydiamond, we do things differently. We turn the air you breathe into the Skydiamonds you wear, shaping a future where luxury and sustainability become one. This is the core of our approach to sustainability.

This Clean Air Day (20th June), we're proud to celebrate our carbon-capture process – a breakthrough that converts atmospheric carbon into something permanent, pure and purposeful. Read our companion piece on World Environment Day: From pollution to Skydiamonds for more on what this means in practice.

Our Carbon Capture Process

Every Skydiamond starts its life in the sky. We extract carbon dioxide directly from the atmosphere and combine it with rainwater, wind and solar energy in our Sky Lab in Gloucestershire. The result? The world's most sustainable lab-grown diamonds – made from nature's elements, not taken from the earth. You can read more about the rainwater usage in diamond creation and what makes our process so different.

"I was looking for ways to not just capture carbon from the atmosphere but hold it in a permanent way, and of course, a diamond is the purest form of condensed carbon. Importantly for me, it's also a chance to show people there is another way, a better choice than land mining without compromise."

This process makes our lab-grown diamonds carbon-negative, removing more CO2 from the atmosphere than we emit in production. To put it in context, a traditional mined diamond emits over 160kg of CO2 per carat. Our process avoids all that – and goes a step further – making Skydiamond a powerful part of the climate solution. To understand why some lab-grown diamonds are a cut above the rest, it comes down to exactly this kind of process detail.

The Vento Ring: Sustainable Luxury Inspired by Nature

Inspired by our sister company Ecotricity's wind turbines – spinning gracefully to produce green energy – we designed the Vento 5.27ct Asscher Cut Ring.

The Vento encapsulates movement, renewal and transformation – a dramatic piece made from a conflict-free diamond, born from the sky and powered by nature. The setting reflects a modern, sculptural silhouette, symbolising the future we're shaping together.

Why Our Carbon Capture Process Matters

Skydiamond goes beyond creating a beautiful piece of jewellery – it's about making a meaningful choice. Our lab-grown diamonds cut emissions, save energy and reduce water usage when compared to traditional mining.

"Our process starts by capturing carbon directly from the atmosphere and combining it with rainwater under precise conditions, allowing carbon atoms to form into a diamond lattice with the help of renewable energy."

Every stone we produce avoids the destruction of habitats and the human upheaval often associated with mining. It's a future-proof, responsible form of luxury – a diamond made without compromise.
