Diamonds have a wide variety of uses since they are the toughest substance to date on Earth. However, under normal circumstances they are not any good for conducting electricity unless they are of the rarer form type IIB. Diamonds can however be used to conduct heat. Diamonds are formed from carbon that is held deep in the Earth under great pressure and heat. The altered carbon is then forced up to the surface from the mantle in a uniqe form of magma called kimberlite which erupts from diatreme and pipe volcanic vents. The strongly bonded electrons and the compact atoms cause the amazing reduction of the velocity of light through a diamonds mass which is what gives it the lustre which is what most people find appealing about a diamond. It was not until almost 300 years ago that it was discovered that diamonds are a form of carbon. Over 150 years later, a method of being able to produce a synthetic diamond was finally discovered. Due to the toughness of a diamond, only a diamond can cut other diamonds. However, due to its tough nature, it has many industrial uses from cutting and polishing to grinding and is heavily used in the production of industrial rock drills. Although mainly used in the industrial sector, diamond is also a high-tech material that is beginning to be used more often in home electronics, appliances, and automobiles. When it comes to jewellery, diamonds are one of most popular of all the gems. Diamond jewelry is considered a classic from weddings and engagements to anniversaries and even celebrity awards ceremonies. Due to the hardness of a diamond, jewellery containing diamonds is normally made from 18 carat gold as the setting needs to be of a certain hardness to hold the diamond. In the 15th century, Archduke Maximilian of Austria presented Mary of Burgundy with a diamond ring on their engagement as a romantic gesture. Since this time, diamonds have been seen as a symbol of love, joy and romance. Although it started with a diamond ring, all diamond jewellery is now seen as a token of everlasting love and perfection. It is also traditional to wear diamonds as a symbol of achievement and a symbol of status and success. Although diamonds are measured by carat, unlike gold, this is not the main factor in deciding the cost of the diamond. Diamond prices can differ quite a lot based on color, clarity and cut. There are often impurities in diamonds that cause them to have a hint of color rather than being clear. These diamonds are generally less expensive than a clear diamond, however, depending on their cut may still demand a reasonable price. Cutting colored diamonds requires that the diamond is cut to enhance the color. In the case of a clear diamond, it can be cut with a deep cut, shallow cut or perfect length. This is the only human contribution that helps determine the price of the diamond. A diamond displays the maximum amount of reflectance for a transparent substance, displaying what is called an 'adamantine' lustre. However, it cannot be polished again and again as it loses its properties.
