Diamonds are formed when carbon-containing materials (like coal) are subjected to extreme pressure and heat over long periods in Earth's mantle. The carbon atoms rearrange into a crystal lattice structure, creating diamonds. Graphite requires different formation conditions, obsidian is volcanic glass, and coal doesn't just become a smaller version of itself.
