Kimberlite pipes represent the conduits of long-eroded volcanoes, which formed during the explosive eruption of volatile-rich magmas sourced from the deep mantle (>200km). They are the primary source of diamond although not all kimberlites contain diamond. At present, there are four active Canadian kimberlite mines that produce diamonds (Ekati, Diavik, Victor and Snap Lake) giving Canada a significant share of the global market.

金伯利岩管代表了长期侵蚀火山的通道，这些火山是在来自深部地幔（> 200 km）的富含挥发分的岩浆爆发期间形成的。它们是钻石的主要来源，尽管并非所有金伯利岩都含有钻石。目前，加拿大有四个生产钻石的金伯利岩矿（Ekati、Diavik、维克托和Snap Lake），使加拿大在全球市场上占有很大份额。
