A diamond is a form of carbon A diamond is a form of carbon that was created deep within the core of the earth more than 3 billion years ago and brought to the surface by volcanic eruption. In diamond, each carbon atom is bonded to four other carbon atoms in a tetrahedral structure, like a pyramid. Each link or bond is the same length, and the tetrahedral formation is therefore completely regular.Theoretically a perfect diamond crystal could be composed of one giant molecule of carbon. After the magma cooled, it solidified into kimberlite, where the precious rough diamond is still found today. It is the strength and regularity of this bonding which makes diamond very hard, non-volatile and resistant to chemical attack.
