The Cullinan Diamond I: 530.2 carats (106.0 grams)
This breath taking diamond was discovered in South Africa in 1905 and was known as “The Star of Africa.” It was the largest rough quality diamond ever discovered in the history of man. When it was first examined in its raw state the piece was a staggering 3,106,75 carats (621.35 grams),
but even after being polished it’s still an incredible 530.2 carats, (106.0 grams). Unfortunately, it’s true that nothing lasts forever, eventually this national treasure was divided up into 9 individual pieces.
