They are strong, sparkly, bright and expensive. Ever wondered where diamonds come from?
Well, diamonds are no more than pure carbon atoms which go through very high pressure and high temperature which tightly pack the atoms together, bringing that black stone into life (and fire, lots of fire!)
Diamonds are formed in the mantle of the earth, the thick layer between the thin crust and earth’s metalcore, a high-pressure region that has a temperature of over 1,000 degrees Celsius and there is a lot of high pressure, that combination is what is necessary to grow diamond crystals in the earth.
It takes 1 to 3.3 billion years for the diamonds to form. That is the main reason they are so expensive, beautiful, indestructible and unique.
The diamonds reach Earth’s surface through very deep-seated volcanic eruptions, which have not happened in recent times. Those eruptions carried already formed (rough) diamonds to the earth surface, through carrot-shaped pipes called kimberlites.
