    geologyscience.com/rocks/igneous-rocks/kimberlite Kimberlite is an igneous rock that major source of diamonds.Kimberlite is a variety of peridotite.It is rich in mica minerals content and often in form of crystals of phlogopite. Other containt abundant minerals are chrome-diopside, olivine, and chromium- and pyrope-rich garnet.Kimberlite is typically found in pipes – structures with vertical edges that are roughly circular in cross-section.
