Question

What rocks make Diamonds?

Answer 1

Diamond:

• Diamond is an allotrope of carbon $\left(\mathrm{C}\right)$ and is the hardest substance known.
• A type of ultrabasic volcanic rock called kimberlite is formed deep in the crust of the earth. In these rocks, diamonds are found.
• It is formed at very high pressures.
• In diamond, each carbon atom is bonded to four carbon atoms in a tetrahedral manner and forms a three-dimensional arrangement.
• The structure of the diamond is shown below:

Hence, diamond is formed by kimberlite rocks.
