Discover the Blue Moon — A Sensational Blue Diamond

The Blue Moon Diamond is a true marvel, proof of the powerful beauty that is created when nature and human ingenuity work together harmoniously. Internally flawless, the Blue Moon has been christened “one of the rarest gems in the world,” and the GIA has declared that its Fancy Vivid hue might be so unique as to be indescribable. This spectacular gem will be offered as a major highlight of Sotheby’s  Magnificent Jewels and Noble Jewels sale in Geneva on 11 November 2015.
