What is a Diamond?

Diamond name comes from the ancient Greek word adamas, which means invincible. It is the hardest known natural material in the world.

Diamonds hardness and high dispersion of light make it useful for diamond rings, diamond earrings, diamond pendants, diamond necklaces, and diamond bracelets.
Diamond is treasured as gemstone since it's use as religious icons in India at least 2,500 years ago.

Diamond can only be scratched by other diamonds, it maintains its polish extremely well and keeps its luster over long periods of time.

These qualities make it a well-suited ornament to daily wear. It is widely preferred gem in diamond rings, diamond earrings, diamond pendants, diamond necklaces, and diamond bracelets.

Diamond is commonly judged for it's qualities by the four Cs, that are carat, clarity, color, and cut. Nearly half of all diamonds originate from central and southern Africa, however significant sources of diamond have been discovered in Canada, India, Russia, Brazil, and Australia also.

Diamond can be found in nearly any color, however yellow and brown color diamonds are most common. Colored diamonds contain impurities or structural defects that accounts for their color, while pure or nearly pure diamonds are transparent and colorless.

Diamonds that are brought to the Earth's surface by magma in a volcanic pipe can erode out and be dispersed over a very large area. A primary source of diamonds is the term used to describe a volcanic pipe containing diamonds. A secondary source occurs where a number of diamonds accumulate due to the activity of water or weather. Diamonds have been found in glacial deposits, yet are not found in large numbers, and are not considered a potential commercial source of the gem. It is also possible for diamonds to be forced to the surface after two continental plates collide, although it is rare.
