The dazzling potential of lab-grown diamonds

Lab-grown diamonds or synthetic diamonds are purer, cheaper and more sustainable than natural diamonds, so why are we still mining them? New technologies are opening the door to new hi-tech applications and a more sustainable production process. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What can we do and how the system needs to change.
