Hardcore Pawn: Chicago (2013)

Season 1: Episode 15

For $60,000, Randy and Wayne buy a set of flawless diamonds that Wayne thinks was cut from the Marlborough diamond, a 26-carat diamond that was part of a 1980 London robbery committed by two Chicago-based mafiosi: Joseph Scalise and Arthur Rachel.[14][15] While Randy would rather just have the diamonds certified, Wayne had a diamond expert friend of his examine them instead, thinking that if it was the Marlborough diamond, he could get reward money exceeding the money they paid for them.
