Diamants : Que cachent nos bagues de fiançailles ?

 An immersion into the world’s largest diamond mine: Hugo Clément reveals the hidden side of Botswana’s mining industry. In a cavernous pit ≈ 1.5 km wide, only 0.00001 % of the ore is diamond. Crushing the rock and extracting the gem requires massive water volumes, which are then pumped into storage basins to let sediments settle. Poorly maintained basins can fail, spilling water into the environment. Hugo Clément also visits factories producing synthetic diamonds overseas and French jewelers who craft rings using reclaimed diamonds.
