This Blue Moon Diamond will soon be auctioned at Sotheby’s auctions.

The Blue Moon Diamond and the strong saturated color diamonds represent only a tiny part of all natural diamond, and only a minute percentage of all natural color diamonds are blue.

The blue color comes from traces amounts of the element boron in the crystal structure. Less than one boron atom per million carbon atoms is sufficient to produce the blue coloration.

The clarity of the diamond is also important. It describes the size and number of inclusions in a diamond.

The diamond that will soon be sold at Sotheby’s auctions was discovered by Petra Diamonds, in January 2014, in Africa.

The 29.62-carat rough blue diamond is called that way because it comes from its rarity.

Another extremely rare and fascinating feature of this diamond is the highly unusual red phosphorescence, which can be observed when the stone is exposed to ultraviolet light.

The Blue Moon Diamond is being sold by New York-based Cora International, which is one of world’s leading manufacturers of exceptional diamonds.

The diamond is considered the largest cushion-shaped fancy vivid blue diamond to ever appear on the action block.

David Bennett, worldwide chairman of Sotheby’s international jewelry division, calls the diamond “magical and sensational” stone of perfect color and purity.

“Blue for me is the most mysterious and magical of all diamond colors.” said Bennett “This one will now take its place among the most famous gems in the world.”

The cushion-cut Blue Moon has been rated internally flawless and ‘fancy vivid blue’ by the Gemological Institute of America. This is the GIA’S highest possible color grading for blue diamonds.

“While any diamond with natural blue coloration is a rare discovery,” Bennett said, “Some are so exceptional that they emerge only once in a lifetime. A blue moon. This diamond is one of those remarkable occurrences.”
