Ecotricity founder to grow diamonds 'made entirely from the sky'

UK millionaire Dale Vince says lab-grown gems will be ‘world’s first zero-impact’ diamonds

A British multi-millionaire and environmentalist has set out plans to create thousands of carats of carbon-negative, laboratory-grown diamonds every year “made entirely from the sky”.

Dale Vince, the founder of green energy supplier Ecotricity, claims to have developed the world’s only diamonds to be made from carbon, water and energy sourced directly from the elements at a “sky mining facility” in Stroud.
