At 102.34 carats, this masterpiece of nature is the rarest white diamond ever to come to the market and the largest, round D colour flawless diamond known to man.

The only stone of its kind ever graded by the GIA, the diamond has achieved the highest rankings under each of the criteria by which the quality of a stone is judged.

The diamond is D colour; of exceptional clarity (it is completely flawless, both internally and externally); and has excellent cut, polish and symmetry.

As with the famous Cullinan I and Koh-i-noor diamonds, which are part of the British Crown Jewels, the stone is part of the rare subgroup comprising less than 2% of all gem diamonds, known as Type IIa. Diamonds in this group are the most chemically pure type of diamond and often have exceptional optical transparency.

The stone has now found a buyer and, while the identity of the new owner cannot be revealed, the stone was purchased for a price per carat that far exceeds that for any colourless diamond sold at auction.
