Next month Christie’s Geneva is auctioning an exceptional blue diamond ring. Diamond experts have estimated this diamond ring featuring a fancy deep blue diamond to fetch up to $14.1 million US dollar. The reason for the high diamond price is mainly due to the rare color and clarity of the center diamond.

A Blue Diamond: Top Lot

A blue diamond-graded type IIb

GIA graded the center diamond in the platinum ring as fancy deep blue. This grade for a colored diamond is rare to find, especially for larger diamond sizes. A 7.03-carat rectangular-cut diamond with clarity VVS2 is therefore rare. This explains the valued estimate of $14 million by the auction experts. 

The greatest cause of the blue tone in IIb blue diamonds is the boron element. Only 0.1% of all-natural diamond is graded IIb, making them one of the rarest of natural diamonds. The boron absorbs secondary colors (such as red, orange, and yellow) in the blue stone, which is preferred for colored diamonds as one hue, and is more valuable.
