A Brief Natural History Of Diamonds: How Diamonds are Formed

As you may already be aware, diamonds are formed from carbon, primarily being subjected to enormous pressure. Over thousands of years materials such as the long dead leaves of prehistoric plants firstly decayed to peaty humus, then gradually break down into other organic materials including carbon. These ancient carbon deposits were exposed to high temperatures and incredible geological pressure for many millennia eventually being transformed into completely different compounds altogether - probably most prized amongst these being diamonds.
