The special marks the 50th anniversary of the diamond's donation to the National Museum of Natural History by Harry Winston, its last private owner. "Mystery of the Hope Diamond" will premiere Nov. 21.
The diamond was discovered in India in the 17th century. Its owners have included King Louis XIV of France and King George IV of England. For many years, the 45-carat diamond was considered cursed, and it glows a fieryred when placed under an ultraviolet light.
The museum hasn't placed a value on the diamond, but the network says some have claimed it would be worth hundreds of millions of dollars. During the special, the diamond will be placed in a new setting and worn by model Hilary Rhoda.
