50 Important uses of Diamonds

Deep in the earth’s crust, millions of years ago Diamonds were formed. Intense pressure and extreme heat crystallized carbon atoms into formidable tetrahedral bonds that could not be broken, creating one of the hardest substances known to man.  

The earth’s core is divided into three layers, Crust, upper mantle, mantle, outer core, and inner core. Geologists believe that the earth’s mantle has a temperature of between 900°C to 1300°C and a pressure of between 650,000 psi and 850,000 psi, just the right conditions for diamond formation. 

The stable immobile continental shelf called craton, mostly found in Africa and Australia creates perfect diamond creating zones. After being formed diamonds lie deep in the earth’s crust for years, before finding their way to the earth’s surface through kimberlite pipes.

There are three ways Diamonds are formed in nature:

Diamonds formed in the subduction zone

These are formed when tectonic plates collide, and one landmass is forced underneath the other, creating a subduction zone. Materials that are rich in carbon melt under the high temperature and extreme pressure forming pockets of Diamonds.

Diamonds formed by Asteroid impact

The other is when an asteroid strikes the Earth’s surface. This collision results in a massive explosion of heat and pressure on the ground. Carbon-based deposits in the impact crater are instantly crystallized into diamond specks.

Diamonds formed by meteorite fall

Diamonds can also be created in outer space, through meteorite showers that sometimes find their way to the earth’s surface, depositing showers of Diamond crystals.

Interestingly Diamonds can also be created in Laboratories. These Nanodiamonds as they are known are one of the greatest man-made inventions. There are two ways of manufacturing diamonds in the laboratory:

High-Pressure High Temperature

This is energy-intensive relatively low production rate; seed crystals grow at a few microns per hour.

Chemical Vapor Deposition

This is another method of making diamonds on a commercial scale. In this process, diamonds are grown in a controlled environment of hydrocarbon gas mixture. It’s an easier method to set up compared to the High-Pressure High-Temperature method.

You now understand why Diamonds are rare in nature, it’s not easy to create them. Now, let’s turn to how these rare gemstones are used in daily life:
