This large rough diamond was found in the Democratic Republic of Congo in 1990. An estimated 65% of the world’s diamonds come from African nations, and this nation yielded an astonishing cut diamond weighing 203.04 carats. This makes it the second largest colourless and flawless diamond in the world (with the highest purity rating of D; the scale goes from D to Z). It is currently owned by the De Beers Group, a diamond industry controlling company which was founded by the British mining explorer Cecil Rhodes. At carat weight alone, the final cut diamond would be worth at least $5 million. But because of its fame, purity and its irreplaceable nature, this gem has been valued at over $160 million.
