The kimberlite pipe at the famous Kimberley diamond mine in South Africa is the archetype, typifying their narrow surface area (approximately 40,000 sq m /450,000 sq ft) and great depth (from more than 1,000 m/3,500 ft below the present land surface to the limit of mining). Kimberlites & lamproites are known from scattered localities throughout the world – only some are. S. The vast majority of minable diamonds come to the surface in a kimberlite – a type of intrusive igneous rock originating in the asthenosphere, a region from about 80-200 km below the earth’s surface. 12. Magma existing in Kimberlite pipes pushes diamonds and other stones rapidly (a few hours) through the earth’s crust and mantle. What does kimberlite look like? Kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix. This is why kimberlite pipes are the sites of most of the world's diamond mines.
