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.
