Meet the man who counterfeits the world's most famous diamonds -- legally!

BJ member John Hatleberg will take you on a private tour of his studio - the tour that he gives to curators from the Smithsonian, Christie's and Sotheby's. John will unlock the mysteries behind the most world's famous gems, the Koh-i-Noor, the Centenary and the Hope Diamond - all of which are among the gems that he has replicated - by request - legally, of course. This is a rare treat for gem lovers, and puts a new light on all things that sparkle.
