1.0 Introduction
Historically, most of earliest diamonds were found in India where the first diamond mine in the world were developed (Edward and Hausel 2002). Today, diamond deposits are found in some locations as different situations. For instance, diamonds have been found and mined in southern Africa and the largest deposits are currently in Siberia (Yelisseyev et al., 2013). However, the largest diamond mine in the world is at Argyle in northern Western Australia that produces 25 million carats of diamonds a year and around 30% of the world's production (Andrew, 1998).
The locations are geologically known as cratonic lithosphere which are the primitive foundational basement rocks and where first continents have been created (Andrew 1998).
The diamond formation requires a special condition. As diamonds are considered that they are from deep inside the earth, it must meet the special condition which high temperature and pressure. However, some of diamonds we have found such as microdiamonds are located at not corresponding places with the condition. When this fascinating mystery was solved, new discoveries and evidences for wide range of studies were come out. This paper will examine the formations one by one then retrieve evidences to reveal one common myth.

The geologic history of this diamond is summarized as subduction of ocean floor basalt that had experienced low temperature alteration by sea water resulted in prograde metamorphism of the basalt (Daniel et al., 2004). This affinity between microdiamonds within rocks and continental plate tectonic processes have contributed multidisciplinary investigations such as continental collisions, mountain building, and the earth's thermal evolution (Larissa et al.,
When standing on top of the butte, the rock that makes up a majority of the area is quartzite. Quartzite is a metamorphic rock that forms when existing rock is exposed to extreme amounts of heat and pressure (4). The quartzite that is found on Kamiak Butte was formed sometime around 1.47 to 1.4 billion years ago during the Paleozoic period of the Precambrian era. Many of the metamorphic rocks have been fractured and decayed due to physical and chemical weathering, but because quartzite consists of one of the strongest minerals quartz...

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)
Some of the highest producing diamond mines are countries in Africa. Countries that had some of the highest rate of conflict were Angola, The Democratic Republic of Congo, Sierra Leone, and Liberia. The ...
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...
One very important piece of information is that gemstones and crystals are grown during the cooling, formative stages of Earth’s development and so it has lead me to the conclusion that they are gifts from nature. According to physics, gemstones and crystals consist of natural balances and solid sta...
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.

Scientists can tell how old something is based on the amount of carbon 14 in a dead object. Carbon dating is accurate if the amount of carbon 14 in the atmosphere remains the same throughout time. The second is if carbon 14 has always decayed at the same speed, and the last is if all living things absorb the same amount of carbon as the atmosphere has in it ("Child Evangelism of Hawaii"). Diamonds are formed when carbon is under a large amount of pressure and heat. When diamonds come from the ground, they don't look shiny.
The field of geology has many different branches. Some of these areas have hardly anything in common. The one thing that they all include, though, is that each one concentrates on some part of the Earth, its makeup, or that of other planets. Mineralogy, the study of minerals above the Earth and in its crust, is different from Petrology, the st...
Mining is the process or industry of obtaining minerals from the earth. Topics in this paper I’ll be specifically discussing are pros and cons of mining, structures of a mine, mining in general, California gold rush, diamonds in Africa, and comparison of diamond and gold mines.
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 youngest coal is not even coal yet it’s called peat. It is cut from the earth, dried and burned for heat. The energy content of peat is quite low.
