The diameter of a kimberlite pipe at the surface is typically a few hundred meters to a kilometer (up to 0.6 mile). Kimberlites are the most important source of primary diamonds. Many kimberlite pipes also produce rich alluvial or eluvial diamond placer deposits. However, only about 1 in 200 kimberlite pipes contain gem-quality diamonds.
Kimberlite is a relatively rare type of lava. It comes from depths as great as 300 to 350 kilometers. On its way to the surface, kimberlite frequently picks up rock and mineral fragments, including diamonds, one of which can be seen in this sample.
