The 101.38-carat pear-shaped flawless diamond - The Key 10138, which carries a pre-sale estimate of $10 million - $15 million, will be sold by Sotheby's on July 9 in Hong Kong. Sotheby's said it would be the first time a diamond of such size has been offered for public purchase with cryptocurrency.
The Key 10138 was given its name to symbolize the unlocking of a new era in commerce and technology, and thus is a key to history. The diamond is accompanied by a GIA report stating that it is D Colour, Flawless and by a diamond type classification letter stating that it is determined to be a Type IIa diamond. The Key 10138 will undoubtedly become a diamond that history remembers as it takes the culmination of humanity’s work and knowledge on diamonds thus far, and turns the key to unlock a still more brilliant future, Sotheby's said.
