Sotheby’s Diamonds, a retail boutique specialising in the world’s finest diamonds, recently unveiled a rare 102.34-carat white diamond, which it said was flawless according to every critical industry benchmark. 

“The stone is the only known round brilliant-cut diamond over 100 carats perfect according to every critical criterion: In addition to the high number of carats, the stone is also perfect in colour, clarity and cut,” revealed the company. 

The stone was unveiled in celebration of the first anniversary of Sotheby’s Diamonds’ New Bond Street salon in London. At 102.34 carats, the diamond is the “rarest white diamond ever to come to the market and the largest, round D-colour flawless diamond known to man,” Sotheby’s Diamonds added. 

Patti Wong, founder and chairman of Sotheby’s Diamonds, commented, “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. With its outstanding weight, its perfect colour, clarity and cut, it is a masterpiece of nature brought to life by human hand, blazing with a brilliant firework-like display of almost every colour on the spectrum – mesmerising to behold.”

The only stone of its kind ever graded by the Gemological Institute of America, 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 (the highest grade for a white diamond); 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 percent 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, according to Sotheby’s Diamonds.
