Everything You Wanted To Know About Diamonds.

Diamonds are the hardest substance known on Earth and are good conductors of heat but poor conductors of electricity though some rare forms, particularly the grey-to-blue ones called type IIB, are semiconductors, and are somewhat conductive.

The force of being buried under great pressure and heat is what causes carbon to form into diamonds. These are then pushed up to the surface in a rare type of magma called kimberlite and forced out from a diatreme or pipe type of volcanic vent.

The strongly bonded electrons and the compact arrangement of its atoms account for the remarkable reduction of the velocity of light through its mass thus giving a diamond its appeal.

It was first discovered to be carbon in 1796, and it took more than 150 years from that time until a method of diamond synthesis was invented.

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.

Diamonds are also very popular as jewellery as they portray a classic look in design. Diamond jewellery is used throughout all forms of celebration from weddings, engagements, anniversaries and even sometimes for awards ceremonies.

Diamond jewellery is made using 18KT of gold because gold must have certain hardness for setting diamonds.

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.

The reflectance that is shown with a diamond is called an 'adamantine' lustre. However, if you continually polish a diamond the adamantine properties gradually diminish and the diamond will lose its lustre.
