World's Largest Rough Diamond
The world's largest documented rough diamond is the Cullinan weighing 3,106.75 carats (0.62 kilograms). Named after Sir Thomas Cullinan that owned the South African mine that found the stone in 1905.
The stone was later cut into two smaller, polished stones; the Great Star of Africa, which weighs 530.20 carats, and the slightly smaller Lesser Star of Africa, which weighs 317.4 carats. Additionally 104 smaller stones were made, each being nearly flawless in both color and clarity. The Great Star of Africa currently rests in the Tower of London.
