Koffiefontein is a small farming town in the Free State province of South Africa. The name means coffee fountain in Afrikaans.
In the 1800s, Koffiefontein was a stopover spot for transport riders travelling between the coast and the diamond fields and gold mines to the north. "Coffee fountain" is a reference to the strong coffee brew transport riders made during their stopover. "Coffee fountain" involved transport riders grinding their own coffee beans (often with a spoon) and using the water of a natural spring to boil for the brew. Upon the discovery of diamonds near the natural spring in 1870, a town quickly developed at the Koffiefontein stopover spot, as prospectors began to mine the area in search of high-quality diamonds.
The diamonds of Koffiefontein were known to be of the "first water"; meaning of very good clarity. The diamond mine established by De Beers in 1870 was closed down in 2006. The mine was then acquired by Petra Diamonds in 2007 and is currently still in operation. Although the mine and supporting businesses have employed a large number of the local population, the area is still characterised by poverty. Census data indicate that 57% of the Koffiefontein population are below the poverty line.
