Diamonds were curiosities which used to simply be picked up off the ground in India from the 8th to the 12th century BC. The stones were found in kimberlite sludge along the riverbeds. Virtually all diamonds came from India until the late 19th century. They also produced by far the whitest diamonds. The Indian dominance ended at the end of the 19th century.
From that point onwards South Africa appeared to be the new Walhalla for diamonds. That is where the Kimberley mine can be found, also known as ‘The Big Hole’. This acquired its name from the same kimberlite, which protects the diamond against lava when it comes up to the surface.
