A Diamond is one of the two natural minerals that are produced from carbon. The other mineral is Graphite. Even though both of these minerals are produced from the same element ,carbon, they have totally different characteristics. One of the most obvious difference is that Diamond is hard and Graphite is soft. The Diamond is considered to be the most hardest substance found in nature. It scores a perfect ten in hardness. Because of its hardness a tiny Diamond is used as a cutting and drilling tool in industry. Even the Greeks called the Diamond “adamas” which means unconquerable. Diamonds also conducts heat better than any other mineral .
Diamonds come in several different color shades such as, yellow, blue, green, or pink. One reason why a Diamond has different colors is through the processes involving heat and radiation. Another reason is that 99.5% of a Diamond is Carbon and the rest are different trace elements. These 0.5% of elements are the reason why a Diamond has different color shades. For example Nitrogen causes it to have a yellow tint , and Boron a blue shade. The pink color in some Diamonds are thought to be caused by deformation of the atomic structure of the diamond crystal. A pure Diamond , which would be 100% carbon, is colorless
Diamonds were created million years ago, when the earth was formed, the material experienced pressure of 5million times the atmosphere at sea level and temperatures between 1000~1200degreesC. These conditions caused carbon in the layers inside the planet to crystallize into diamonds. The diamonds moved up to the earth’s surface through volcano eruptions. This is why many Diamond mines are near volcanoes. Diamonds occur in two types of rock: Kimberlite and Lamprolite. Diamonds are mostly found in South Africa, India, Brazil, Russia, Australia, and Arkansas. Right now about 100million carats are mined each year. Today the largest cut Diamond in the world is the Cullian I at 530.2ct .
The unit cell of a Diamond is cube. Five carbon atoms form tetrahedra at the cube corners , at the centers of each of the cube faces, and at four sites within the cube. The carbon atoms are located at the center of each tetrahedron . The carbon tetrahedra are covalently bonded, which explains why diamonds are extremely hard. The toughness of the Diamond comes from four planar directions of weakness , it is called octahedral cleavage .
A diamond ain't a thing in the world but a piece of dirt that got
...sumption, creates emission of greenhouse gases and other harmful chemical materials. 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. The health of the environment and the health of humanity are as one. Whatever we do to our planet, we do to ourselves. Reducing energy consumption of diamond mining not only helps protect our planet, but also helps protect the health of our people.
Should diamonds be seen as such highly sought-after, luxury goods, and marketed and sold at such extravagant amounts? While some individuals might be of the impression that diamonds are lavishly priced, because of limited supply, it is of my opinion that a very shrewdly-created cartel disguises the very reason for these “rare” gems seemingly being worth your “pretty penny”.
In July of 1914 he was sold up to The Boston Red Sox. Babe would call Boston home for the next five years, and made his first major league start on July 11th, 1914. In that first game against the Cleveland Naps, he pitched all but two innings, and the Red Sox left the game with with a 4-3 win, and this made the left handed young star happy. Some say Ruth got over excited as the next game they played the Detroit Tigers, he got hit almost every other at bat. Ruth’s bad performance led him from being a left handed pitching star, to being a left bench rider. He was sent back down to the minors to a team called the Providence Grays(Babe Ruth). He also only spent a little time there, and was called back up the the Sox right before the world series. Babe pitched his first full game victory on October 2nd, 1914 against the yankees. It is very rare For a baseball player to pitch a full game, and Babe did it as a rookie in the world series, against the legendary yankees. Babe also hit a double, to get his first major league hit ever
Valuing a diamond is a highly skilled task thus not traded on world frequently. (Valued on the basis of four criteria- 4C s carat clarity color and cut)
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.
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.
To begin diamonds are can be found all over the world including countries like, Botswana, Canada, Namibia, Russia, South Africa, Australia, and Tanzania. Yet, diamonds are still quite rare and are only found from two dominant deposits. The primary deposits often consist of diamond-bearing “pipes” of volcanic rock called kimberlite. Deep within th...
Baseball has helped create many special memories of my childhood. It is a great way for people
“Baseball was, is and always will be to me the best game in the world” -Babe Ruth. Baseball is one of America’s most popular sports, and it is said to be the best in the world by one of, if not the most popular and well known athletes in American History. Babe Ruth is the player that if a non-baseball fan was asked who they knew from the sport, they would say Babe Ruth. He is also very well known for being one of America’s most successful athletes, and he agrees that baseball is the best sport in the world. Despite the fact that one of the most iconic American figures states that baseball will never cease to be the greatest sport in the world, people argue today that the sport is nothing compared to what it used to be. To an extent, this statement
For the past sixty-seven years, the citizens of India have embraced their country’s independence all the while seeking to regain their past. Prior to this renewed sense of freedom, India had belonged to the British Empire. From 1858 to 1947, the British government claimed India and its inhabitants as a colonial possession. Before the British Empire laid claim to the vastness of India, the British East India Company helped to oversee the transfer of the Kohinoor Diamond from the Sikh Empire to their motherland in 1851.

It is composed of two elements; oxygen and sulfur. This mineral can either be white in colour, gray, brown, orange, green, red, pink, yellow, beige, or it can be colourless, and the streak that it leaves is white. Based on the Moh’s Hardness scale, Gypsum falls somewhere around the 2 margin. Its lustre is close to that of glass (in properties and in appearance), and is considered vitreous. The cleavage—where it breaks along its line of weakness—is 1,1 – micaceous ; 2,2 and its fracture is uneven. Gypsum is slightly flexible, has low hardness, where it can be scratched by a fingernail, and is sectile (can be cut with a knife). Gypsum is a sedimentary rock, meaning it was formed by cementation at the surface of the Earth near bodies of water; it causes the mineral (gypsum) to settle within the
This essay will start looking at the foundation of De Beers and how he initiated his marketing campaign and what the effect was on the prices of diamonds. Diamond is commonly known as a material that possesses unique qualities physically. It contains a strong covalent bond between its atoms. Diamond is majorly known for its hardness as well as lasts thermal conductivity in comparison with bulk material. Such properties make it useful in industrial application such as cutting and polishing tools.
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.
