Diamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure. As a result, diamond is very hard and has a high melting point.It does not conduct electricity.iamond is a form of carbon in which each carbon atom is joined to four other carbon atoms, forming a giant covalent structure.

Diamonds formed and stored in these diamond stability zones are delivered to Earth's surface during deep-source volcanic eruptions. These eruptions tear out pieces of the mantle and carry them rapidly to the surface [3]. See Location 1 in the diagram at the top of the page.
