In 1866, a small, white pebble, which turned out to be a 21-carat diamond, was found on the banks of the Orange River in South Africa. When a second, larger diamond was found in 1871, a diamond rush brought miners to the area by the thousands. Eventually, five big holes were dug, and the largest, known as the “Big Hole,” yielded three tons of diamonds before it was closed in 1914. What company, founded during the rush, is now responsible for about 40 percent of the world’s diamond production? Discuss
