WebWhile carbon atoms are arranged in a hexagonal manner in graphite, in diamonds, each carbon atom is linked to four others in a tetrahedral manner. Hence graphite is like sheets of carbon atoms that are stacked one over the other; carbon atoms in diamonds form a pyramid-like structure. WebWhat is carbon's role in forming diamonds? Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals.
