The Smithsonian’s National Museum of Natural History held a press conference this morning (the Post even sent someone to cover it) to show off the Hope Diamond, now on display for the first time ever without any kind of setting. The 45.52-carat diamond has been at the museum for 50 years, but always in its traditional setting, a pendant circled by smaller diamonds on a diamond necklace. The naked blue gem will now remain on display until April 2010, when it will be placed into a temporary new setting, and then sometime later, returned to its original setting.
