The step-cut fancy vivid blue diamond weighing 15.10 carats.


Accompanied by GIA report no. 2223179803 stating that the diamond is Fancy Vivid Blue, Internally Flawless; also accompanied by a diamond type classification letter stating that the diamond is determined to be a Type IIb diamond. Type IIb diamonds are very rare in nature (...less than one half of one percent)...today the most significant source is limited to the Cullinan mine in South Africa...Among famous gem diamonds, the 70.21 carat Idol's Eye and the 45.52 carat Hope are examples of Type IIb.

 

Further accompanied by a separate monograph expressing the rarity and the characteristics of the stone, as well as a letter stating that ‘The 15.10 carat Fancy Vivid Blue diamond…is among the rarest of any category of gems…To achieve a Fancy Vivid grade with a step cut or emerald cut the inherent body-color has to be stronger than virtually every other fancy shape. This is the largest of this specific cutting style that is both Fancy vivid and Internally Flawless. The combination of this diamond size, saturated color and Internally Flawless clarity grade make it truly unique.’
