The Cullinan diamond is not fully intact; instead, it has since been cut into nine large stones and nearly 100 smaller ones. This cutting, however, does not diminish the value, as all of the stones are valued at millions of dollars together. “Star of Africa I,” or “Cullinan I,” is the largest stone to come of the original Cullinan diamond. Estimated at 530 carats, the diamond is the largest cut colorless diamond in the world.
