DIMONDS rhomb is the best cognize gem. It is known as the might of gems for its brilliance and for being the unassailableest mineral on reason. (Foa, p.50) Its characteristics enable it to be used for many diametrical purposes. Since infields are the awkwardest gems on Mohs scale, they contend useful tools for industrial purposes, such as drilling disenfranchised materials. However, they are quite rare, which vexs them really valuable. Their beauty and brilliance farm them perfect for jewelry. Â Â Â Â Â Â Â Â diamond is make up of carbon. An otherwise compose of pure carbon is black lead. plumbago is the stable form of carbon, set apart up at the earths jump. Despite the position that they name identical chemic composition, the two minerals are drastically different. adamant is the hardest known tenderness and is usually light unilateral and transparent, eyepatch graphite is greasy, comfortably 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 booking nuclear arrangement. Graphite, on the other hand, although it is the same element, is more loosely jammed and has a six-sided, forge configuration, which makes it soft (Pough, 1991). The differences between graphite and diamonds are accounted for by the conditions in which they are created.
Diamonds form everywhere massive periods of time, between nose candy km and 200 km beneath the surface. At this large depth, carbon gets a notice 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 anyplace between 10 and 30 km/hour and affix their velocity to several hundred km/hour inside the last few kilometers. (Pough, 44) At the surface, this lava cools and turns into Kimberlite rock. That is why... If you indispensableness to get a full essay, order it on our website:
