What are the minerals of a diamond?

Natural diamond is a mineral composed of a single element–carbon (C). It has a cubic crystalline structure. It generally occurs in the form of octahedral crystals with curved faces, with cubic crystals being rarer. Diamonds are usually colorless.

What is special about mineral diamond?

Diamond has many unequaled qualities and is very unique among minerals. It is the hardest known substance, it is the greatest conductor of heat, it has the highest melting point of any substance (7362° F or 4090° C), and it has the highest refractive index of any natural mineral.

What are the 5 properties of a diamond?

Properties

• Hardness.
• Low coefficient of friction.
• High thermal conductivity.
• High electrical resistivity.
• Low thermal expansion coefficient.
• High strength.
• Broad optical transparency from ultra violet to infra red.
• Resistant to chemical corrosion.

Why diamond is the hardest mineral?

The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth.

How are diamond formed?

Simply put, diamond formation occurs when carbon deposits deep within the earth(approximately 90 to 125 miles below the surface) are subject to high temperature and pressure. Some stones take shape in a matter of days or months, while others take millions of years to materialize.

What is a diamond made of?

Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals.

Where is diamond mineral Found?

The following countries produce industrial grade diamonds: Australia, Botswana, Brazil, China, Congo, Russia and South Africa. Geologically speaking, natural diamonds are found in two environments. Most are found in kimberlites, which are pipe-like formations created as a result of volcanic and tectonic activity.

What type of rock is diamond?

igneous rock
The diamond is the hardest natural substance known. It is found in a type of igneous rock known as kimberlite. The diamond itself is essentially a chain of carbon atoms that have crystallized. The stone’s unique hardness is a result of the densely concentrated nature of the carbon chains.
