What you need to know


Diamonds are precious stones consisting of a clear and typically colorless crystalline form of pure carbon, They are the hardest naturally occurring substance and are extremely desirable in many cultures.

Most natural diamonds are formed at high-pressure high-temperature conditions existing at 140 to 190 kilometers deep in the Earth mantle. Carbon-containing minerals provide the carbon source, and the growth occurs over periods from 1 billion to 3.3 billion years. Diamonds are brought close to the Earth surface through deep volcanic eruptions by a magma, which cools into igneous rocks known as kimberlites and lamproites.
