Largest unseen Diamond

The BBC has an interesting article on the largest unseen diamond:

The Wittelsbach-Graff Diamond was last seen in public at the 1958 World Exhibition in Brussels. After that, it disappeared and its whereabouts remained a mystery until Laurence Graff, a billionaire diamond dealer, bought it at auction in 2008, appending his surname.
He and his son Francois were in the gallery of the Smithsonian’s National Museum of Natural History in Washington DC as the blue stone, was brought up from a secret vault and finally revealed.

Some great pictures in the article too:

    Seems such a shame that such a beautiful diamond was under wraps and hidden from public view for so long.

    Not everyone can afford a diamond as nice as this one. I love blue colored diamonds and buy them from David Rosenberg Diamonds where I live in Boca Raton, Florida. Reasonable prices and all different size stones available.

    The Wittelsbach truely is unique. Even the record sale from 2008 on 24mil USD still holds the world record for its class. A beautifull stone.
