Diamond is a stone that excels in brilliance and displays a striking play of prismatic colors. It is the preferred gem in engagement and wedding rings, which are worn every day. It is also the hardest natural material known, where hardness is defined as resistance to scratching.
Their hardness makes them quite useful in industry as cutting and grinding tools. Diamonds are used to polish, cut, or wear away any material, including other diamonds. There are diamond-tipped drill bits and saws, and diamond powder is used as an abrasive. Less expensive industrial-grade diamonds, known as bort, are used for such purposes.
Diamonds were probably first mind in India over 3,000 years ago (some think over 6,000 years ago). Roughly 49% of diamonds originate from central and southern Africa, although significant sources have been discovered in Canada, India, Russia, Brazil, and Australia.
Today experts in the field of gemology grade diamonds and other gemstones based on the characteristics most important to their value as a gem. Four characteristics, known informally as the four Cs, are now commonly used as the basic descriptors of diamonds: these are carat, cut, color, and clarity.
