The Volcanoes Which Erupt Diamonds; Kimberlite Eruptions

There exists a highly rare type of volcano that on occasions erupts diamonds. Known as kimberlite pipes, these highly explosive volcanoes bring highly pressurized carbon from more than 100 miles below the surface rapidly to the surface, generally in a matter of hours. Stranger still, these types of volcanic eruptions generally occur in areas of the world which have not seen any other volcanic activity for hundreds of millions of years such as in eastern Canada, Brazil, and South Africa. This video will discuss how diamonds are brought to the surface by kimberlite and how a geologic feature known as a craton is an aiding factor.
