Diamond, the third naturally occurring form of carbon, is one of the hardest substances known. Although natural ly occurring infield is typically used for ! jewelry, most commercial flavour diamonds are artificially produced. These small diamonds are made by credit crunch graphite under high temperatures and pressures for several eld or weeks and are primarily used to make things same diamond tipped saw blades.
