Dale Vince of SkyDiamond shares the future of sustainable diamonds mined from the sky 

How Dale Vince came to making diamonds was the result of his out of the box approach. While thinking of ways to capture CO2 from the atmosphere and safely store it in the most permanent way possible, diamonds came to mind. As a diamond is the purest form of carbon, he hit upon the idea of taking carbon from the atmosphere and turning it into diamonds. And so SkyDiamond was born.
