Diamonds

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.

Probably nothing you can bury will ever turn into a diamond, since it's not humanly possible to dig deep enough to access the enormous pressure and intense heat required to form a diamond from carbon.

Yes, diamonds are the hardest naturally occurring substance on Earth. They score a perfect 10 on the Mohs scale of mineral hardness, which measures a mineral's scratch resistance.

Diamonds are extracted through a method called open-pit or underground mining. In open-pit mining, large machinery is used to remove the earth above the diamond deposits. In underground mining, tunnels are dug to access the diamond-bearing rock. Once the diamonds are reached, they are separated from the ore and processed for sale.

NO!!

Diamond is an allotrope of carbon . Where any one carbon is tetrahedrally combined with four adjacent carbons.

Quartz, is an impoure form of SiO2 ( Silicon dioxide). The molecules are in a crystalline lattice, and in that lattice arranged very similar to carbon(diamond).

Diamonds ascend to the Earth's surface in rare molten rock, or magma that originates at great depths. Carrying diamonds and other samples from Earth's mantle, this magma rises and erupts in small but violent volcanoes.

Just beneath such volcanoes is a carrot-shaped "pipe" filled with volcanic rock, mantle fragments, and some embedded diamonds. The rock is called kimberlite after the city of Kimberley, South Africa, where the pipes were first discovered in the 1870s.

Another rock that provides diamonds is lamproite.

The extraction process can take place at the mine site, where the excavated material is washed and tumbled. Because diamond is heaviest of all the materials mined, it falls to the bottom and is otherwise sorted from the mined materials.

Diamonds are mostly found in kimberlite pipes, which are vertical shafts formed by ancient volcanic eruptions. They are also found in alluvial deposits, which are sedimentary deposits of eroded material from the kimberlite pipes. Diamond mining is concentrated in countries like South Africa, Russia, Botswana, Canada, and Australia.

Yes, diamonds are typically found underground in the Earth's mantle, at depths of around 150-200 kilometers. They are brought to the surface through volcanic eruptions in a type of rock called kimberlite pipes.

Since not all diamond deposits have been discovered -- or fully mined, it is not possible to answer your question with any accuracy.

Diamond mines in several African countries, in Canada and in Australia are profitable enough to be considered 'rich' in the sense that they make more money than they cost to operate.

Diamond is the hardest natural substance which is at all common, and was given the highest number on the Mohs scale, 10. Some synthetic nanomaterials and a couple of very rare minerals are harder.

No, the center of the Earth would not melt a diamond. Diamonds have a very high melting point of about 3,550°C (6,422°F), which is much higher than the estimated temperature of the Earth's core, which is about 5,700°C (10,300°F) to 9,000°C (16,000°F).

This is a question without an answer.

What is clear, however, is that extracting diamonds from the earth is expensive and dangerous: diamonds are not as common as air or water, for example.

It is not possible to determine how many diamonds there may be on earth, but it may be accurate to write that diamonds are not necessarily 'in abundance' on earth.

Diamonds found in volcanoes are typically formed deep within the Earth's mantle under high pressure and temperature conditions. They are brought to the surface during volcanic eruptions through volcanic pipes called kimberlite pipes or lamproite pipes. These diamonds are known as "kimberlite diamonds" or "volcanic diamonds".

Alluvial diamonds are those found under water having been washed away from the volcanic pipe where they erupted from the earth's mantle by flowing water.

You can find alluvial diamonds in riverbeds or in the sea.

Diamonds are typically mined through environmentally destructive practices such as open-pit mining, which can lead to deforestation, habitat destruction, and water pollution. Additionally, the diamond industry has been linked to human rights abuses and conflicts in certain regions where diamonds are sourced. The carbon emissions associated with diamond mining and processing also contribute to climate change.

The largest diamond mine in the world is the Jwaneng diamond mine in Botswana. Jwaneng mine is jointly owned by the Debswana Diamond Company and the Botswana government. It produces some of the highest quality diamonds in the world.

Short answer: No.

Longer answer: Diamond is made of carbon. Carbon that has been subject to extremely high pressure and heat for a long time becomes diamond. The longer the carbon is exposed to such conditions, the larger the diamond that will be formed. Over millions of years, carbon deposits slowly crystallize into diamond.

A natural place where the extreme conditions needed to form diamonds exist is deep inside the Earth. At some 90 miles or 150 kilometers under the continental crust, the pressure is known to be around 5 gigapascals and the temperature around 2,200 degrees Fahrenheit or 1,200 degrees Celsius.

Natural diamonds are brought to the surface of the Earth by way of volcanic pipes. Where diamonds have been formed, diamonds are included in these eruptions, as well as 'indicator minerals' such as kimberlite. Often diamonds are 'attached' to volcanic matter, from which the diamond stones are separated.

Lab-created diamonds have the same physical, chemical, and optical properties as mined diamonds. Both types are durable and can be used in jewelry. The main difference is the origin: lab-created diamonds are made in controlled environments, while mined diamonds are formed naturally deep within the Earth.

Diamonds are formed deep below the earth's crust, and come to us once the volcanic eruption forces the material to the surface. The vertical geology takes the form of a pipe -- a volcanic pipe. (Read link, below.)

This phenomenon is unusual and uncommon in the world, thus lowering the numbers of places where diamonds can be found.

It depends on the elements! If two of them are carbon and hydrogen, hundreds of compounds can be made from these elements alone. If the four elements are all noble gases, no new substances can be made from them by chemical reaction.

Carat is the unit of measure for diamond weight.

Karat rating may be appropriate for gold and its level of purity.

A rock is mineral like a crystal .Also they both are solids

A mineral, by definition, is any naturally occurring, inorganic substance, often additionally characterized by an exact crystal structure. Its chemical structure can be exact, or can vary within limits. Elements that occur naturally are also considered minerals like rocks.

A geologist would differentiate between a natural diamond -- formed by a geological process, and a synthetic diamond -- formed by a man-made process.

Both diamonds are 'real diamonds'.
