Today's Diamond of the Day is the Eureka Diamond. This 10.73-carat brilliant is not, by ordinary standards, exceptional. However, it was cut from the first diamond found in South Africa and therefore has historical significance. In 1866 a shepherd boy found a small, shiny stone on the south bank of the Orange River near Hopetown. The pebble was kept for a while by a 15-year-old boy named Erasmus Jacobs, who later gave it to his neighbour, farmer Schalk van Niekerk, a collector of unusual stones.
