This is fascinating episode where we do a brief history of diamonds- what are the biggest, most valuable diamonds, and then we dig into some of the key people -how Cecil Rhodes built De Beers into a diamond monopoly, how Ernest Oppenheimer transformed diamonds by more or less inventing the concept of the diamond engagement ring, how Beny Steinmetz  who built a $6 billion fortune has seen that dwindle and faces extradition and jail terms in different jurisdictions, and how the emergence of lab grown diamonds has exploded in the last decade- it’s a fantastic episode with so many different stories- enjoy.
