The Hope Diamond: A 45.52 carats stone, dark Grayish-Blue with a cushion cut. Winston bought this diamond in 1949 and 10 years later donated it to Smithsonian in Washington DC. This diamond has a long rich history and many believe the stone is bad luck. It is hard to believe but it is said that Winston sent the diamond to the museum via a registered first-class mail. The packaging too is among the display. I have personally seen the stone and it was not what I expected. I was actually disappointed in the diamond but I was very impressed with the massive 70+ carat pink star ruby on display next to the Hope diamond.
