What makes something valuable? In Part Two, we tell the story of how De Beers, the multinational diamond company, used Hollywood to create one of the most successful marketing campaigns in history. Along the way, we hear from precious-metals expert Kevin DeMeritt, founder of Lear Capital. Diamonds might be a girl's best friend, but that desire was carefully and methodically manufactured. Presented by The Licorice Guy.
