Diamonds adorn the fingers, necks, wrists and earlobes of many people around the world.
They represent wealth, beauty and love. Diamond is a clear, hard solid, consisting of an interlocking lattice of carbon atoms. It is similar to graphite in a lead pencil, another form of carbon. However it is more compact and has a melting point of steel. Synthetic diamonds, made from graphite, are used in industry as tools for cutting, grinding and polishing.
