The manner in which a diamond may be cut also adds to the price of a diamond. Its cut also defines the amount of light that will reflect and refract from the piece. If the cut is too shallow or too deep, it allows a lot of light to escape from the other areas. A well-cut diamond will add to the fiery sparkle of a diamond. To maximize this effect, the diamond cutter has to have accurate geometric calculations.
As people started realizing the worth and preciousness of diamonds, they started quarreling over them. Mining for them became a major activity. The Dutch and English fought and tried to establish their control over the mines. The local tribes too came to know about it, and were at war among themselves. Terrorists are known to have enslaved people and even children, to force them work on these mines, for decades. The limbs of people who refused to work on the mines were amputated. It also resulted in the death of thousands of people, since the diamond was discovered. Hence, the diamonds from these regions of Western Africa (Angola, Sierra Leone, Democratic Republic of Congo and Liberia), which were mined by forceful labor and traded illegally by terrorist outfits to fund terror activities, are called 'Blood Diamonds' or 'Conflict Diamonds'.
Diamonds are formed under tremendous heat and pressure. These conditions exist at about 150 to 200 km beneath the Earth's surface, where the temperatures are extremely high ranging from 900 C to 1300 C. For millions of years, carbon atoms deep in the Earth's upper mantle have been exposed to these extreme conditions. As a result, these atoms combine their cubic molecular form, and they ultimately form diamond crystals. During volcanic eruptions, these crystals eventually make their way to the Earth's surface through pipes and channels. These passageways contain the magma from the volcano, which rises along with the diamonds, and deposits them on the surface where they are later found and mined. These are known as the primary deposits of diamond. The igneous rock called kimberlite is the most common host of diamonds found in the earliest volcanic pipes.
It involves coating the crystal with a layer of graphene, which is a one-atom thick substance composed of pure carbon. When the coated crystal is heated to high temperatures in order to bond the two substances, a restructuring and bonding between the two elements can be observed. Since both substances are impermeable, the water trapped between them transforms into a supercritical phase, that possess the ability to steadily corrode the surface of the diamond. However, the purpose of the experiment is not only focused on etching the diamond, but also to study the effect of high temperature and pressure on the characteristics and behavior of different liquids.
