The table demonstrates different kimberlite types have variable diamond counts. Kimberlite is by far the dominant type of eruption to bring diamonds to Earth’s surface (figure 1). These magmas crystallize on cooling into volcanic rocks known as kimberlite and lamproite (see box A). There are two main magma types that carry natural diamonds to the surface.() - Kimberlite, a type of magma that is normally found deep within the Earth’s crust is known to somehow make its way to the surface at times, and when it does, it. Kimberlite is an igneous rock formed from the cooling of olivine-rich magma. Garnet, olivine, rutile, zircon, and more are also associated with kimberlite formations, and not all kimberlite deposits contain diamonds. Diamonds are not the only minerals that kimberlite pipes bring to the surface. Diamonds can be created by smelting Kimberlite Ore in a single step which can be convenient. Its primary use is the creation of Diamond. Although Kimberlite Ore is a rare resource that offers a unique crafting recipe, it is not incredibly valuable. Directly crystallized from Kimberlite magma under CO₂ rich conditions, and diamond can be obtained by further smelting." Usage.

These supercontinents show time lines with (i) broad periods devoid of kimberlite magmatism corresponding to times of continent stability, and (ii) narrow kimberlite emplacement windows corresponding to times of fundamental plate.
There is truly a lot of kimberlite around here.Kimberlite ages span the assembly and break-up of a number of supercontinents, such as Rodinia and Gondwana. It came from the hydrothermal vents that surround the town of Glenwood Springs, CO.

Keep an eye out for the really green soft rock near Independence Pass, it is chock full of gold and is easily crushed. Maybe it was about a carat in size uncut. The size of recovered diamonds ranged from micros to the largest diamond - 28.3 carat gemstone.My partner found a raw diamond high banking near Granite. Diamond grades of kimberlites range from a trace diamond to 135 carats/100 tonnes based on diamond mills in the district that were inefficient and typically rejected diamonds of all sizes. () - Kimberlite, a type of magma that is normally found deep within the Earth's crust is known to somehow make its way to the surface at times, and when it does, it. The total kimberlite tailings accumulated near mine site over several decades of diamond processing is more than 6 million tonnes. The occurrence of diamonds in Kimberlite rock is about 10–12 carats per 100 tonnes of kimberlite rock.
