The Kimberley Octahedral diamond was so enormous that it turned out to be the largest naturally formed octahedral diamond crystal in the world, and it was the seventh largest gem-quality rough diamond ever discovered in the world in 1964. Today it is the 14th largest gem-quality rough diamond ever discovered.The diamond has been preserved in its natural octahedral state, and is yellow with a weight of 616 carats. As the diamond remains uncut the usual color and clarity grades and type of cut applicable to cut and polished diamonds, do not apply for this diamond. The diamond can only be described in terms of its shape (octahedral), color (yellow) and weight (616 carats).
However the intense shades of yellow such as fancy intense and fancy vivid come under Type Ib, but these diamonds are very scarce constituting only about 0.1 % of all naturally occurring diamonds. The canary yellow diamonds also belong to this rare group. The remaining shades of yellow such as fancy yellow, fancy light yellow, light yellow, very light yellow, and faint yellow all belong to Type Ia, which constitute almost 98 % of all naturally occurring diamonds.
The owners of the diamond De Beers Consolidated Mines Ltd., who were aware of the rarity of this exceptional find decided to preserve it for the sake of posterity, as the chances of finding a similar diamond of such enormous size was extremely remote. The diamond is today exhibited in the "Diamond Vault" of the visitors center of the "Kimberley Big Hole" together with the "Eureka Diamond" the first diamond to be discovered in South Africa on the banks of the orange river in 1867.
