Kimberlite pipes, the best source of mined diamonds today, erupt to the earth's surface like any volcano.

Why are diamonds found in kimberlite rock?
Apparently kimberlite pipes -- that can contain diamonds -- are volcanic formations that begin deep within the earth's mantle. Because diamonds and kimberlite -- and other semi-precious gems -- are formed in similar locations, some kimberlite rock contains diamonds. You can read more, below.
Why are diamonds most commonly found in Africa?
Diamonds are brought to the surface from the lower mantle by means of kimberlite pipes. Kimberlite pipes are only found within old cratonic crust, such as Africa.
What is a craton and what is a kimberlite pipe and how are they linked to the discovery of the diamond?
A craton is 'an old and stable part of the lithosphere' -- the earth's crust. One class of inclusions in the formation of the earth's crust when subductions of crust were folded into the deep, kimberlite diamond areas that lie about 150-450 K below the surface. Diamonds as we know them are exploded to the earth's surface through kimberlite pipes, which are carrot shaped and widest at the surface. Although not all kimberlite pipes are sources for diamonds, most diamonds are found in areas where kimberlite pipes occur.
What kind of minerals can diamonds be found in?
Diamonds are associated with carbon as it is one of the allotropes of carbon. Answer:Diamonds are often found in Kimberlite
Are diamonds formed in veins?
No. Diamonds are erupted to the surface of the earth by volcanic pipes, together with other matter, including kimberlite. There is no pattern in the eruption that determines the existence of diamonds.
Are most most diamonds formed inside kimberlite?
All diamonds are formed from carbon. Kimberlite and diamonds are both erupted to the earth's surface via volcanic pipes. Kimberlite is an indicator mineral, increasing odds for geologists that a volcanic pipe includes diamonds: not all pipes erupt diamonds with kimberlite. Kimberlite can be considered a 'neighbor' or 'kin' of diamond, but not a source.
African diamonds are contained in what?
All diamonds are erupted to the earth surface together with indicator minerals, including kimberlite. Other minerals are present in fertile kimberlite -- containing diamonds -- and absent in sterile kimberlite.
Why are diamonds found in kimberlite rock?

Where is kimberlite found?
Kimberlite is a rare, blue-tinged, coarse-grained intrusive igneous rock that often contains diamonds. Some kimberlite deposits have been found in Western Kenya.
Are most diamonds mined directly from Kimberlite?
Kimberlite is an indicator mineral, formed deep within the earth's mantle where diamonds are also formed. Often, they are found together, but not always. Kimberlite is not diamond: they are different minerals.
When diamonds are in the ground what is the rock around it?
Some diamonds may be included in kimberlite.
What is at least one thing in nature that contains diamonds?
Kimberlite can contain diamonds.
What is the name for igneous rock that contains diamonds?
kimberlite
Why kimberlite might be found in diamonds?
Kimberlite is a volcanic rock that is commonly associated with the formation of diamonds. It is formed deep within the Earth's mantle and is brought to the surface through volcanic activity. Kimberlite magma is rich in carbon, which is necessary for diamond formation. As the magma rises to the surface, it cools and solidifies, capturing and preserving the diamonds that formed within it.
Are kimberlite rocks used for human purpose?
Kimberlite is the main ore of diamonds, but otherwise has little use to humans.
Why haven't there been reports of diamonds in kimberlite pipe rocks?
Diamonds are found as loose stones, or can be embedded in other materials, including kimberlite. See the linked photo, below.
What mineral do diamonds come from?
Diamonds are made from carbon, which is an element. They are made within "kimberlite" rock - I do not know if kimberlite is a mineral, or not. Sometimes, diamonds are washed out of kimberlite by the weather, and can be found in placer (PLASS-uhr) deposits, that is, at or near the surface of the ground. There are also diamonds found in meteorites that fell to Earth perhaps 3.5 billion years ago.
