Diamond is a native crystalline carbon that is the hardest known mineral. It is a nearly transparent precious stone. Noble and dazzling diamonds can be said as the desire jewelry of every woman. From the aspect of economic, scarce resources cannot fill the needs of all people. The natural diamonds can only be enjoyed by a small part of people due to its expensive price. However, today’s modern technologies can process artificial gems which have lower cost compared to the natural diamonds. Its high quality even makes the diamond experts hard to distinguish the differences from the appearances because both have same basic physical and chemical properties. There’s only a way to differentiate between natural and synthetic diamonds which is by studying their impurities both microscopic and atomic level. There are several methods used to produce synthetic diamond which …show more content…
In industrial field, synthetic diamond are very useful in the production of laser optics. Other than thermal and chemical stability, synthetic diamond also has an unique combination of low thermal expansion and high optical transparency in a wide spectral range. An optimum exit windows for CO2 lasers are provided by synthetic diamond that make it as an ideal ‘window’ material for several industrial, R&D, defence and laser applications. Moreover, synthetic diamond is also widely used in automotive cutting applications. Among any known material, extending from ultraviolet to far infrared and the millimeter-wave microwave band, synthetic diamond has the widest spectral band. At the core of high power CO2 lasers, disk lasers and solid state lasers, Element Six single crystal synthetic diamond and polycrystalline CVD diamond solutions are found. This enable a stable and enduring high optical quality of the laser beam. Therefore, synthetic diamond has becoming the most trending material for optical windows in high-power CO2 lasers and

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”.

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)
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.
You’re browsing along various websites searching for a new piece of jewelry to add to your collection. Suddenly - you see it. The piece that screams your name. It’s an elaborate piece with large cut diamonds and you just know those can’t be real. But they look so real, so you check out the price.
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...
The energy fields of crystals and gemstones are gaining popularity and attention as tools for the twenty-first century. This is a time of shifting human conscience and many forms of change. Using these tools can help you activate and aid this type of transformation with their abilities to amplify and balance the energy fields that surround our bodies. I believe we are more than just our physical bodies and we store information that roams at will each time that we release a thought. I have learned this from working with many types and forms of gemstones and crystals and I hope this little bit of knowledge I have shared with you gives you the motivation to explore the world of the precious stones all around us.
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.

iii. India dominates the world’s cut and polished diamonds (CPD) market. In value terms, the country accounts for approximately 55 percent of global polished diamond market and nearly 9 percent of the jewellery market. According to GJEPC's provisional estimate, cut and polished diamonds registered 19.06 percent growth in exports at US$ 7.11 mn.
During 2012, Sierra Leone’s diamond industries were unbelievable, and the amount of exporting was over one hundred millions of dollars in U.S. dollars (Sierra). The principles of supply and demand seem central in the characterization of the various trends in the market. In various market structures, the black market tends to be rarely regulated. However, the black market observes in the venture allow for the integration of some strategies in the effort of the market to the interest traders. Traders pegged to the various black market on the places where best deals are secured on illegal merchandise. These goods are defined to be oriented on the interests of the society, as well as the improvement in demands. Veblen goods are the main targets of such market developments. This originates from people increase demand and status of luxury associated to their usage, and implies the prospective capacity of the reduction of the performance of the rest of the goods.
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.
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 .
The value of diamonds lies on their physical properties that make them suitable for many applications. Natural diamonds are only of high value if they are scarce in nature. Realizing this, De Beers Consolidated Mines was formed to control the supply of diamonds from mines across the world. The diamond market is influenced by mine production, rough diamond distribution, preparation/cutting, and retail markets. The project will be concentrating on the retail markets for diamonds and other high end jewelry.
