The eastern (leading) edge of Farallon slab in central North America at 100 and 90 Ma (at 403 km depth) are shown as thick and thin black-dashed line, respectively [after Spasojevic et al ., 2009 ]. The eastern (leading) edge of Farallon slab in central North America at 100 and 90 Ma (at 403 km depth) are shown as thick and thin black-dashed line, respectively [after Spasojevic et al ., 2009 ]. The mantle is nearly 100 miles below the Earth's surface, and gems that come from the mantle are brought to the surface by kimberlite pipes, which are formed by deep-source volcanic eruptions.
Kimberlite Pipes Map. Mesozoic-Cenozoic kimberlite between 250 Ma and 50 Ma is the most remarkable kimberlite bloom globally, and more than 60% of the world's known kimberlite clusters on every continent were emplaced. You can find a map of kimberlite pipes in the USA through geological surveys or research institutions that specialize in diamond exploration and mining
