Under high pressure and temperature, carboncontaining fluids dissolved various minerals and replaced them with diamonds. Much more recently (hundreds to tens of million years ago), they were carried to the surface in volcanic eruptions and deposited in igneous rocks known as kimberlites and lamproites .

The girdle of the diamond is formed first, and then come the various facets. This is a painstaking stage that required accuracy, or else the finished diamond will be virtually worthless. Only the first 18 facets are cut first the table, culet and 8 facets each on the crown and pavilion. This is a substage called 'Blocking'.

Diamonds cost significantly more than coal because they contain a lot of gold. In terms of price, a one pound diamond can range from 2 million to 6 million. A pound of coal is worth a few pennies. Despite the fact that diamonds are more expensive than coal, coal is more valuable. In many ways, diamonds are more similar to coal than coal.

In the creation of a diamond, there was never coal involved. In fact, most dated diamonds are substantially older than Earth's first land plants, which are used as a product when coal is formed. Diamonds deteriorate to graphite under normal settings because graphite has a lower energy configuration.

The process of transforming coal into diamond is known as artificial diamond synthesis, and it involves subjecting the coal to temperatures over 3000°C and pressures of up to 60,000 atmospheres. This process rearranges the atoms in the coal and it is possible to create artificial diamonds from coal.

The process of creating a diamond from coal is known as carbonadoing, and it involves subjecting the coal to extremely high pressures and temperatures. This simulates the conditions that are found deep within the Earth's mantle, where diamonds are thought to form. Interestingly, not all types of coal can be used to create diamonds.
