When the Zaretskys tried to have the diamond insured, a jeweler discovered the gem had been stolen in 2003 by celebrity stylist Derek Khan, according to reports.
Khan borrowed the diamond for a fashion shoot and pawned the gem instead of returning it, according to court documents.
Khan, who made his name by borrowing high-end jewelry in exchange for it being worn by celebrities, was eventually arrested and charged with stealing $1.5 million in jewelry. He spent two years in prison and is now working as a jeweler and personal shopper in Dubai, according to various news reports.
Perhaps it's possible to recover some money from them?
