HIGH PRESSURE, HIGH TEMPERATURE

The diamonds that are formed under the earth’s surface are known as natural diamonds. They are carbon-bearing materials (with a chemical makeup that is similar to coal) that form when exposed to the perfect combination of high pressure and high temperature conditions, occurring between depths of 140 and 180 km beneath the surface of earth, in earth’s lithospheric mantle, or at the site of a meteorite strike. After a period of 1 to 3 billion years, until the diamond is formed, it travels to the earth’s surface by deep-origin volcanic eruptions via streams of molten rock that go through earth’s volcanic pipes.

As it travels, it acquires inclusions and flaws, giving each diamond its own unique fingerprint. No two natural diamonds are alike—each one displays a unique colour or clarity, and is a wonder of the world. Many diamonds can be found in alluvial deposits, along shorelines and in rare cases in glacial deposits. Essentially, a diamond is a compressed form of carbon that come to life only when the most unique set of criteria are met. This is a natural phenomenon, and attribute the diamond’s rarity and value in the world.
