In this last episode of Diamond Road we crisscross the globe, following both the small and the epic journeys of four characters. Manoj, a thirteen year old child polisher from India who leaves his village and his fathers cotton farm to apprentice in the diamond cutting factories of Surat, now a major diamond centre. We also meet Akshay and Arjav Mehta, whose Blue Star Group is one of the largest diamond manufacturing companies in the world. We follow the story of Andy Cohens diamond, an old, challenging stone that Andy won at the Christies auction in New York City.
