In the 1980s, up to $50 million of Argyle Pink Diamonds were smuggled out of one of the world’s most secure mines, seemingly without anyone noticing. The gems were dispersed from Western Australia around the world to Hong Kong, New York and Switzerland with only a few ever recovered.  Journalist Sinead Mangan joins Gemma Bath this week to discuss her investigation into this previously unsolved case.
