In the animal kingdom, humans have the most of a species in quantity, and they are also highest of intelligence in quality hence, humans are the undisputable king of all animals. In the material world, diamonds also enjoy the same royal status, as this material is the most abundant in the universe and also have the most useful properties. In the industrial diamonds have been limited by size and geometry. Therefore, the primary uses for industrial diamonds have been in the mechanical industry as ultrahigh pressure anvils, surgical knives, and most commonly, as superabrasives. Although tetrahedral bonding is the common feature of all semiconductors, diamond has the smallest atoms and therefore it possesses the highest atomic density of all the semiconductors, and in fact, of all materials. Diamond’s dominance as the key element for functions is more due to its enabling capability than to its cost effectiveness.
