London is the place to be for lovers of the exceptional this winter. Recently revealed to the public in hopes that a private collector will do just that–collect–a very, very special Stone which awaits its new home. 

The exceptionally proud founder and chairman of Sotheby’s, Patti Wong, has announced of the stone that “in the course of my long career, which has brought me close to some of the greatest stones the earth has ever yielded, I have not encountered anything quite like this.” 

According to a statement released by Sotheby’s:

“at 102.34-carats, this masterpiece of nature is the rarest white Diamond ever to come to the market and the largest, round D color flawless diamond known to man. [This is] the only stone of its kind ever graded by the Gemological Institute of America (GIA), the diamond has achieved the highest rankings under each of the criteria by which the quality of a stone is judged – ‘the four Cs’.”

The mode of sale currently underway, however, is rather unusual for this caliber of stone…typically, such a dazzling diamond would be put up for auction. Instead, Sotheby’s has daringly opted to quietly keep it available for private purchase. 

According to Sotheby’s statement:

“Only seven diamonds weighing more than 100 carats and with the highest colour for colourless diamonds (D colour) has ever sold at auction; none of them were of brilliant cut.”

Whether it will sell immediately, or not to this generation, is unknown. But what we do know is that if you’re in London and have some spare time, maybe the Rosetta Stone can wait.
