The Hope diamond has left the Smithsonian only four times since it was donated. In 1962 it was exhibited for a month at the Louvre in Paris, France, as part of an exhibit entitled Ten Centuries of French Jewelry. In 1965 the Hope diamond traveled to South Africa where it was exhibited at the Rand Easter Show in Johannesburg. In 1984 the diamond was lent to Harry Winston Inc., in New York, as part of the firm's 50th anniversary celebration. In 1996 the Hope diamond was again sent to Harry Winston Inc., in New York, this time for cleaning and some minor restoration work. The weight of the Hope diamond for many years was reported to be 44.5 carats. In 1974 it was removed from its setting and found actually to weigh 45.52 carats.
