Part 4 of our 'Firm Favourites: Jewellery Houses That Reign' series is about the King of Diamonds himself, Harry Winston.

The American's love of precious gems was legendary and it would be hard to find a diamond of note that didn't pass through his hands at some stage or another. Matty and Alyce swap stories about some of his most well-known acquisitions as well as some of the ingenious marketing strategies that set his Harry Winston, Inc apart.

And of course do listen to the end to join us for another round of Gem Trivial Pursuit!

Producer: Ross Hannon
