Most diamonds are mined from volcanic pipes, where they have been deposited by deep-origin volcanoes drawing material from over 90 miles (150 km) deep within the Earth, where the pressure and temperature is suitable for diamond formation.
It's just that their chemical composition is that of carbon. It's a crystalline form, or allotrope, of carbon. The same thing coal is for the most part. There are different kinds of coal, ranging in different compositions, but mostly all organic.
Synthetically, carbon is used to produce fake diamonds among other minerals.
