If you are hanging out in London, it’s advisable to visit the Sotheby’s Diamonds boutique.
The auction house just revealed «the rarest and most valuable diamond to appear on the open market».

The precious stone is on display at Sotheby's New Bond Street Galleries on 8 - 9 February only. The diamond will not be auctioned but will be sold privately.
Though the asking price is not disclosed yet, the auction house has a justified hope to fetch a world record price.

A 102.34-carat, D-Flawless, Type IIA round brilliant diamond is the only stone over 100 carats to have been given the highest possible grades in every criteria by the Gemological Institute of America. The institute judges the stones’ quality and in a letter dated 8 September 2017 called it the “Largest Round Shaped, D color, Flawless diamond ever graded.” 

Here is a translation from the jewelry buzzword: a D-grade means the purest whitest hue, a Flawless index points, that even when viewed under a microscope there’re no blemishes, and, finally, a Type IIA rate indicates a chemical purity, in other words, a clarity to the eye.

The diamond was cut from a 425-carat rough stone mined by the De Beers group in Botswana.
The cutting and polishing process, performed by the most experienced artisans, took over six months and required the diamond to be transported between Johannesburg and New York. 

'With its outstanding weight, its perfect color, 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 color on the spectrum’, raved Patti Wong, founder and chairman of Sotheby's Diamonds.

The sale of the superlative stone marks a year since the opening of the Sotheby's diamond boutique in London.

The current record price per carat for any colorless diamond is $260,000, established at the auction in Hong Kong in 2013. While the giant 163.41-carat emerald-cut stone featured in the De Grisogno necklace, sold for $33.7 million in Geneva in 2017, holds the current record for the most expensive D-Flawless diamond.

The exceptional quality and rarity of the round diamond mesmerize the jewel collectors. But will the glittering gem beat the world’s records?
