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. When the Smithsonian's gallery was renovated in 1997, the necklace was moved onto a rotating pedestal inside a cylinder made of thick bulletproof glass in its own display room, adjacent to the main exhibit of the National Gem Collection, in the Janet Annenberg Hooker Hall of Geology, Gems, and Minerals. The Hope Diamond is the most popular jewel on display and the collection's centerpiece. In 1988, specialists with the Gemological Institute of America graded it and noticed "evidence of wear" and its "remarkably strong phosphorescence" with its clarity "slightly affected by a whitish graining which is common to blue diamonds." A highly sensitive colorimeter found tiny traces of a "very slight violet component" which is imperceptible to normal vision. In 2005, the Smithsonian published a year-long computer-aided geometry research which officially acknowledged that the Hope Diamond is, in fact, cut from the stolen French Blue crown jewel. In 2009, the Smithsonian announced a temporary new setting for the jewel to celebrate a half-century at the National Museum of Natural History. Starting in September 2009, the diamond was exhibited as a stand-alone gem with no setting. It had been removed from its setting for cleaning from time to time, but this was the first time it would be on public display by itself. Previously it had been shown in a platinum setting, surrounded by 16 white pear-shaped and cushion-cut diamonds, suspended from a chain containing forty-five diamonds. The Hope returned to its traditional setting in late 2010. On November 18, 2010, the Hope Diamond was unveiled and displayed at the Smithsonian in a temporary newly designed necklace called "Embracing Hope", created by the Harry Winston firm. Three designs for the new setting, all white diamonds and white metal, were created and the public voted on the final version. The Hope Diamond also is resting on a new dark blue neck form, which the Harry Winston firm commissioned from display organization, Pac Team Group. Previously, the Hope Diamond had been displayed as a loose gem since late summer of 2009 when it was removed from its former Cartier-designed setting. A Smithsonian curator described it as "priceless" because it was "irreplaceable", although it was reported to be insured for $250 million.
