DIMONDS rhomb is the best known gem. It is known as the mogul of gems for its brilliance and for being the unassailableest mineral on earth. (Foa, p.50) Its characteristics enable it to be used for many different purposes. Since diamonds are the hardest gems on Mohs scale, they ask useful tools for industrial purposes, such as drilling hard materials. However, they are quite rare, which vexs them very valuable. Their beauty and brilliance make them perfect for jewelry.

         diamond is made up of carbon. Another frame of pure carbon is graphite. Graphite is the stable form of carbon, put up at the earths surface. Despite the fact that they name identical chemical composition, the two minerals are drastically different. adamant is the hardest known substance and is usually light colored and transparent, eyepatch graphite is greasy, easily powdered, and very dark in color. Diamond is the hardest gem on Mohs hardness scale and graphite is the softest. Diamond is very hard because of its dense packing and interlocking nuclear arrangement. Graphite, on the other hand, although it is the same element, is more loosely jammed and has a six-sided, layered configuration, which makes it soft (Pough, 1991). The differences between graphite and diamonds are accounted for by the conditions in which they are created. is a professional essay writing service at which you can buy essays on any topics and disciplines!

Diamonds form over massive periods of time, between 100 km and 200 km beneath the surface. At this great depth, carbon gets a chance to calm very gradually, forming diamond crystals. When volcanic goions occur, magma carries the diamonds up to the surface of the earth. Kimberlite lavas carrying diamonds erupt at anywhere between 10 and 30 km/hour and increase their velocity to several hundred km/hour within the last few kilometers. (Pough, 44) At the surface, this lava cools and turns into Kimberlite rock. That is why...
