Kimberlite is an igneous, oftentimes diamond-bearing rock that is named after the town of Kimberley, South Africa. The original frontier town was called New Rush, and quickly homes and businesses arose from the barren landscape. In June 1873, New Rush was renamed Kimberley. The 1869 discovery of the Star of South Africa Diamond (an 83.5-carat (16.70 g) spawned a diamond rush to the area which resulted in the open-pit mine called the "Big Hole." The morphology of kimberlite pipes and the classical carrot shaped brecciated fragments seen in it is the result of explosive diatreme volcanism from very deep mantle derived sources. Volcanic explosions produced vertical columns of rock that rose from deep magma reservoirs.
