For its first four decades in the National Museum of Natural History, the Hope Diamond lay in its necklace inside a glass-fronted safe as part of the gems and jewelry gallery, except for a few brief excursions: a 1962 exhibition to the Louvre; the 1965 Rand Easter Show in Johannesburg, South Africa; and two visits back to Harry Winston's premises in New York City, once in 1984, and once for a 50th anniversary celebration in 1996. To guard against theft during the diamond's trip to the 1962 Louvre exhibition, Switzer traveled to Paris with the Hope Diamond tucked inside a velvet pouch sewn by his wife. The Hope Diamond was placed into the pouch, which was pinned inside Switzer's pants pocket for the flight.
