In 1893, a worker in the Jagersfontein Mine discovered a diamond
in the truck in a pile of gravel. He kept the stone until he was able to provide it to his manager. This diamond
was largest stone discovered in the world until the Cullinan I diamond was found. It is now the second largest
The diamond weighed approximately 971 3/4 carats and had a high-clarity,
blue-white tint. It had an irregular shape and was cut into 21 stones, with the largest being a marquise that weighed
approximately 69.80 carats. A smaller, 18-carat marquise stone cut from the Excelsior was displayed at the 1939
World's Fair by De Beers.
