Jonathan Goldberg sat for hours each day cutting diamonds from rough stones into the polished diamonds you see in jewelry. As a trained diamond grader he worked in a diamond-cutting factory, and in the diamond-trading centre of Antwerp. After doing an MBA, Jonathan worked as an investment banker, and friends asked about the best place to buy a diamond engagement ring. Which led him to found Kimberfire, where he’s now CEO of a company offering a new way to buy diamonds.
