Jagersfontein is a small town in the Free State province of South Africa. The original farm on which the town stands was once the property of a Griqua Jacobus Jagers, hence the name Jagersfontein. He sold the farm to C.F. Visser in 1854. A diamond rush started in 1870 after farmer J.J. de Klerk found a 50 carat (10 g) diamond.
