Sold at Christie's London for $24.3 million - 35.56ct Cushion Shape Natural Blue Diamond Wittelsbach - Graff
This 35.56-carat, cushion-shaped diamond sold at a Christie's London auction in December 2008.Thelegendary deep grayish-blue gem from India passed through the hands of many royal families and spent two centuries in the House of Bavaria as the family diamond of the Wittelsbachs, according to Christie's.
It was recently renamed the Wittelsbach-Graff Diamond.
The internally flawless diamond previously weighed in at 35.56 carats, however through re-polishing to bring out the color by its owner Laurence Graff, the stone's weight decreased. The Gemological Institute of America has noted the rare diamond to be "the largest, Flawless, Fancy Deep Blue, Natural Color we have graded to date..." I wonder if Infanta Margarita Teresa realized what a very lucky girl she was when this was in her possession.
