What is diamond ?

Diamond is a clear transparent precious gemstone composed of pure crystallized carbon which has been highly compressed over millions of years. Diamonds are the hardest substance known to mankind, rating a 10 on the Mohs scale. They are valued because it is difficult to produce a faceted diamond and when properly cut they have high refractivity and brilliance. The quality and value of a diamond is rated using the "4 C's" of color, cut, clarity and carat weight. (See individual listings).
