What are diamonds made of and how are they made?
Diamonds are made of carbon atoms, bonded in such a way as to create crystal formations. In high-temperature, high-pressure environments, such as is present in the earth’s mantle, carbon atoms bond in a particular formation of five atoms. Each carbon atom naturally forms to four other carbon atoms.
