People who live around Johannesburg are probably used to seeing mine towers and mine dumps, but us peeps from down at the coast aren't. This meant that when I got to visit the Cullinan diamond mine close to Pretoria north of Johannesburg a little while ago it was like discovering a whole new world. The thing that literally stands out like a sore thumb at a mine is the mine tower. Below are two different angles of the tower at Cullinan.
Just for interest sake. This mine is where the Cullinan diamond was found. It is the largest rough gem-quality diamond ever found, at 3,106.75 carats. The largest polished gem from the stone is named Cullinan I or the First Star of Africa, and at 530.2 carats was the largest polished diamond in the world until the 1985 discovery of the Golden Jubilee Diamond, 545.67 carats. The Cullinan I is now mounted in the head of the Sceptre with the Cross. The second largest gem from the Cullinan stone, Cullinan II or the Lesser Star of Africa, at 317.4 carats, is the fourth largest polished diamond in the world. Both gems are in the Crown Jewels of the United.
