Diamonds from Land, Sea and Air
Stones aren't just dug up out of the ground anymore - increasingly they're also grown out of thin air and dredged from the bottom of the sea, as presenter Ed Butler discovers.
Stones aren't just dug up out of the ground anymore - increasingly they're also grown out of thin air and dredged from the bottom of the sea.
Presenter Ed Butler visits the workshop of innovative jewellers 77 Diamonds at a secret location in London, where they hope to do to the gemstone industry what Uber has done to taxis.
He also speaks to Debmarine, the Namibian company that hopes to pluck more stones from the ocean than parent de Beers does from its traditional mines in South Africa. Plus Ritu Raj of Diamond Foundry explains the clever "alchemy" behind man-made diamonds.
