Diamonds atomic moment 18 unmingled gems composed of carbon and atomic number 18 the hardest inherent substance in the world. In addition to this, they also stupefy the highest thermal conduction of 20-25 W/cmK, which is 5 times to a greater extent then copper. Diamonds in its most pure form are colourless, although some may train traces of Boron or nitrogen, which in combination pass by it different colours such(prenominal) as yellow, blue, green and black. The freight of diamond is measured in carats (one carat = 0.2 gram). Diamonds have a high refractive advocator of 2.4175 and a high distribution of 0.044 which makes it a highly valued stone. Diamonds typically crystallize in the cubic crystal remains and consist of tetrahedrally bonded carbon atoms. The prime(pr enominal) of diamonds drop be split broadly speaking into the categories; gem, near gem, industrial and boart. Most economic diamond deposits contain 20 to 40% gem quality diamonds which can be employ for jewelry, the different 60% to 80% are used for industrial purposes. Diamonds are prized for their brilliance ( magnate to reflect light), fire (the ability to refract and deal light) and scintillation (ability to twinkle). course occurring diamonds are extremely rare compared to other minerals, although gem quality synthetic diamonds can be made by exposing carbon to extreme heat. Naturally occurring diamonds are nearly all over several one thousand thousand years old and are formed deep within the Earth (between 100km and 200km below the surface) low tremendous heat and pressure. The diamonds are carried to the surface in magma tubes during volcanic eruptions. However, scientists believe that these eruptions must be forceful, so that the magma moves up at high speeds, be cause otherwise the... !
