Have you bought a diamond recently? Would you really know where it came from?

This documentary investigates Zimbabwe's diamond trade, going deep into the Marange diamond fields and uncovers evidence of torture camps and wide-scale killings.

A torture camp run by Zimbabwe's security forces is operating in the country's rich Marange diamond fields. Now, soldiers and paramilitary police from Zimbabwe have broken ranks to speak out about a 2008 operation in which civilians working in the Marange diamond fields were massacred.

Hear testimony from survivors and unearths evidence of the brutal and violent crackdown that leads directly to the security forces under the command of the Zimbabwean government.

Then in Hatton Garden, the jewellery district in London, see whether a ban on conflict diamonds from Zimbabwe's Marange region is working.

As the international community argues over whether Zimbabwe's diamonds should be sold on the open market, will President Robert Mugabe ever face prosecution for these crimes?
