Sotheby’s Rare Blue Moon Diamond



Sotheby’s Rare Blue Moon Diamond – 12.03ct

It is the nearly the end of September and the Sotheby’s blue diamond seem to be the magnet for the October auction.

 

The 12.03 rare internally flawless blue moon diamond is one of its kind. It is the largest ever cushion cut diamond to appear on auction. Sotheby’s will  be auctioning this rare blue moon diamond on November 11 at the Magnificent Jewels and Noble Jewels sale in Geneva.

 

The diamond got its name the ‘Blue Moon Diamond’  due to the rarity of its flawless clarity and its the highest possible colour grading for blue diamonds. The name stems from the expression ‘once in a blue moon’ symbolising the rarity of the diamond.

The Gemological Institute of America (GIA) which gave the diamond the highest possible grading given fro blue diamonds and state the colour of the diamond was “likely to have never before been seen within such a large diamond or any gemstone.” GIA also state that “While any diamond with natural blue coloration is a rare discovery, some are so exceptional that they emerge only once in a lifetime. The Blue Moon Diamond is one of those remarkable occurrences.”

 

Due to its condition and rarity, the diamond is estimated to be sold for a price somewhere between $35 million and $55 million (£22.5m – £35.5m). The diamond will be exhibit in Hong Kong October 2-6, in London October 18-22 and in New York City October 30 to November 1. From there, it’ll travel to Geneva for auction.
