It is interesting that most of this effort was simply for producing pigment for tools, clothing, and body art.

The discovery of diamonds in 1867 in the Cape Colony of South Africa had a profound effect on the world's supply of diamonds. For the ten years following the discovery a once extremely rare material became more accessible to Western society. Scientists learned that diamonds came from volcanoes. South Africa still maintains its position as the major diamond producer but there are other famous mines located in other areas.
