Diamonds are a source of attraction every human over thousands of years as a diamond has its own unique, shining and beautiful. Moreover, diamonds also conducts heat better than any other mineral. But where and how did the diamond formed? On this occasion, we will discuss the history or origin of the formation of diamonds on earth. However, nowadays people know that the diamond originated from the minerals in the world but they do not know which minerals can form a diamond.
Diamond is the hardest natural substance and the most valued gemstone. Besides, together with a sparkling luster and high excellence, diamond occupies the top position compared to other gemstones. Diamond is a mineral that is mined in very intensive and evaluated more rigorously than other gems. The quality and value of a diamond is based on the four elements of color, clarity, cut, and carat. The color of a diamond varies from colorless to a rather yellowish, viscous yellow, brown, green, blue, pink, and red (Hall, 1994).
Diamonds earned its original name from the Greek word “adamas” that means "invisible" (Oldershaw, 2005) because it is considered as the most hard mineral that is cannot scratched in with other minerals. In addition, the diamond is a unique jewel of other gems as formed from a single chemical that is carbon. Furthermore, it is doubtful that diamonds actually contain chemicals that are similar to those of Graphite and charcoal. The difference is only in the process of formation where diamonds are crystallized in the form of a cube under the pressure of large earth pressure and high temperatures up to thousands of degrees Celsius. Thus, the bonds of the carbon atoms in diamond are very strong and uniform to produce crystals that ...

  • From the Mines to the Wedding Finger: The Journey of a Blood Diamond

    1994 Words  | 4 Pages

    Deep within African mines, elusive diamonds lay enveloped in the Earth’s crust. Possessing much influence, beauty, and tension, nature’s hardest known substance causes parallel occurrences of unity and destruction on opposite sides of the globe. Diamonds, derived from the Greek word "adamas", meaning invincible, are formed deep within the mantle, and are composed entirely from carbon. Moreover, only under tremendous amounts of heat and pressure can diamonds form into their preliminary crystal state. In fact, diamonds are formed approximately 150km- 200km below the surface and at radical temperatures ranging from 900-1300 C°. When these extremes meet, carbon atoms are forced together creating diamond crystals. Yet how do these gems, ranking a ten on Moh’s hardness scale, impact the individual lives of millions of people besides coaxing a squeal out of brides-to-be? These colorless, yellow, brown, green, blue, reddish, pink, grey and black minerals are gorgeous in their cut state, but how are these otherwise dull gems recognized and harvested? Furthermore, how and why is bloodshed and violence caused over diamonds in Africa, the supplier of approximately 65% of the world’s diamonds? (Bertoni) The environmental, social, and economic impact of harvesting, transporting, and processing diamonds is crucial because contrary to popular belief, much blood has been spilled over first-world “bling”.

Once released into the air, it can cause environmental problems, which in turn threatens not only the environment, but also the health of the people who live in it. In order to reduce the use of energy to help protect our planet and our health, the diamond mining industry has implemented renewable energy programs to monitor energy and carbon emission. Since its beginning, mining company PHP Billiton program has saved an equivalent of one million liters of diesel fuel per year at their Ekati Diamond Mine in Canada’s Northwest Territories.

  • History and Popularity of Diamonds in Africa

    1311 Words  | 3 Pages

    The history and popularity of diamonds in Africa all began in 1866 when the first diamond was found along the banks of the Orange River. In the next fifteen years, Africa became the leading supplier of diamonds in the world, exporting more than nations such as India and Brazil. The discovery of these highly valued and highly demanded diamonds brought an immense amount of trade into Africa, a continent known for its poverty. One diamond company in particular, De Beers, instantly became interested in African diamond mines. By 1888, the company controlled the entire market, connecting African diamonds to wealthy humans all over the world. In 1929, De Beers began marketing diamonds to the middle class as well and associated the diamond with engagement and marriage, increasing the demand of the diamond worldwide. Though the company felt they had a hold on the market, they were wrong. Soon Lebanese traders discovered the enormous profit they could make by smuggling diamonds out of the country. As a result illicit mining and trading increased throughout countries in Africa and especially in Sierra Leone. To make matters worse, the government seemed to overlook the problem, if not sometimes encourage it. One Sierra Leone leader, Siaka Stevens, encouraged illicit trading to gain more control over the diamond mines. Succeeding leaders did the same, and with a corrupt government, the country of Sierra Leone was very vulnerable for a rebellion. Instead of bringing the continent of Africa out of its years of poverty stricken hardship, the discovery of diamonds in Africa only brought more of a curse as it fueled civil war, created political instability between governments, and caused unimaginable human suffering for African citizens.

  • The Conflict Diamonds of Africa

    1039 Words  | 3 Pages

    A beautiful precious diamond can last forever, but what most people do not know is that a majority of our diamonds come from Africa. The civil wars in Africa over diamonds began around 1961 and ended in 2003. Conflict diamonds were rampant and it would be difficult to say if any jewelry sold prior to 2003 was conflict free. Conflict diamonds are diamonds that have been mined and were controlled by African rebels. The rebels would use the profits from selling conflict diamonds to fund illegal activity and to purchase more weapons for their armies. While rebels had control of the diamond mines they killed approximately 4 million people and countless families were displaced.

  • The Truth About Blood Diamonds

    2857 Words  | 6 Pages

    It’s hard to imagine that a mineral could be fueling wars and funding corrupt governments. This mineral can be smuggled undetected across countries in a coat pocket, then be sold for vast amounts of money. This mineral is used in power tools, parts of x-ray machines, and microchips but mostly jewelry. Once considered the ultimate symbol of love, the diamond has a darker story. "Blood" diamonds or "conflict" diamonds are those mined, polished, or traded in areas of the world where the rule of law does not exist. They often originate in war-torn countries like Liberia, Sierra Leone, Angola, and Côte d'Ivoire were rebels use these gems to fund genocide or other questionable objectives. Even with a system known as the Kimberly process which tracks diamonds to prevent trade of these illicit gems, infractions continue as the process is seriously flawed. The continuation of the blood diamond trade is inhuman, and unethical, and in order to cease this illicit trade further action to redefine a conflict diamond, as well as reform to the diamond certification prosess is nessasary.

    Finally, it's very clear that the emergence of life is way more complicated than it seems and that's the reason why it's hard to visualize as a single event. Therefore, scientists are way far away from establishing a life in the laboratory because they were unable to find and provide evidence of exactly what caused life to emerge on earth 4.5 billion years ago. But, one thing that they can say confidently is that minerals, certainly played very complex and fundamental role in the origin of life. Another way this article relates to the material we have covered in class is by minerals because we did analyzed in chapter one that minerals are naturally occurring inorganic solid elements or compounds with a particular chemical composition or range of composition and a characteristic internal structure.

In fact, some may think that conflict diamonds do more good than harm because it “helps” the diamond miners. These miners are working, getting pain, although it is a small amount of pay, and staying out of trouble. They are not being rebels killing innocent people and they are learning more about this carbon solid rock.

    One morning, a well-known gentleman went into a bank in London, and was received immediately by Mr. Alexander Holder, head of the bank. He asked for a loan of fifty thousand Pounds. Mr. Holder asked him to present collateral to cover that large sum of money; the man showed him a crown that belongs to the country. Knowing the risk, Mr. Holder agreed to lend the gentleman that large sum of money if he pays it back in a few days. After the gentleman left Mr. Holder decided to keep the crown all the time near by him, so he took the crown to his home in Streatham. There he lived with his only son Arthur and his niece Mary who was an orphan. He told them about his story with the crown of diamonds. When the father was going to sleep, Arthur asked for two hundred pounds. He refused to give him thinking his son was spoiled by his rich friends who had nothing to do except watch horses. Before going to sleep, he went to check that all windows and doors were locked. He saw Mary at a side window at the hall. She closed it quickly, and Holder noticed that she looked anxious. After he went to sleep, he heard some noise that woke him up; he waited until he heard it again coming from his sitting room. He jumped out of his bed and saw his son holding the crown broken from the side and three diamonds were missing. In grief, he accused Arthur of being a thief and a liar. Meanwhile Mary came in and seeing the crown fainted. Arthur asked if he could leave for five minutes but Holder refused and called the police to take his only beloved son to jail. The police searched the house but could not find anything and advised Holder to get the help of Mr. Holmes the famous detective.
