Hairy, 20, was identified as the seller of the gold belcher necklace, worth £6,500, which had been stolen in a robbery of a 50-year-old man in Queensgate car park, on September 20.
Three days later, on September 23, a 10-inch portion of the chain was sold at a pawnbroker in Long Causeway, Peterborough.
Hairy was arrested and charged with handling stolen goods which he admitted in court.
Hairy, of no fixed address, appeared at Peterborough Crown Court on Thursday, December 9, where he was sentenced to two years in prison.
DC Rob Giffen, who investigated, said: “I hope this sentence demonstrates the seriousness of handling stolen goods – if you play a part in crime, we will come after you.”
