How Are Diamonds Made?

Diamonds are precious stones that are often referred to as the ultimate symbol of love and wealth. Diamonds are essentially made up of carbon atoms that are rigidly fixed together making them robust and extremely long lasting and durable.

There are three essential ingredients that are necessary for diamond formation. Those ingredients are heat, pressure and time. Without these ingredients, diamonds would not exist. Therefore, these components need to be considered when explaining what diamonds are made of. 

Heat, Time and Pressure 

What Are Diamonds Made Of?

Diamonds began formation within the Earth’s mantle more than a billion years ago.

The heat and pressure form the diamond and they travel to the surface of the earth when the volcanoes erupt.

They also move to the Earth’s surface when Earth plates shift naturally. Diamonds are also formed with the intense heat and pressure of asteroid strikes. 

In order for diamonds to thrive they need a very hot temperature. A minimum of 752 degrees Fahrenheit is needed.

The best environment for optimum diamond formation is approximately 160 km below the ground.

Colored Diamonds 

A lot of people love to buy diamonds that are fancy colors.

Clear colourless diamonds are the most popular and well known diamonds in the world however, diamonds actually come in a myriad of colours such as black, blue and purple.

These colours are formed as a result of mineral defilement or lattice destruction. Purple diamonds are formed as a result of plastic contamination and black diamonds are formed as a result of graphite formation.

Blue diamonds are formed as a result of nitrogen contamination. 

What Diamonds Are Made of In the Lab

As a result of the astronomical  cost of naturally formed diamonds geologists introduced specific ways to create robust diamonds in the lab. It is believed that lab diamonds were initially introduced in the 1950s by Swedish and American geologists and researchers. They discovered that it was possible to create diamonds by converting graphite and molten iron. 

Lab diamonds are obviously not natural but they use a very similar process to create the diamonds. They take advantage of high temperatures, pressure and carbon.Lab diamonds look no different to naturally formed diamonds and they are significantly cheaper making them a very popular choice in recent years. 

Lab diamonds are formed by utilizing natural or laboratory  formed diamond seeds . Scientists use diamond seeds to make exact replicas of real, naturally formed diamonds.

Lab diamonds are formed using heat, pressure and chemical vapor deposition. Lab diamonds are formed very quickly which is one of the major advantages of this type of diamond. Scientists can actually create a lab diamond in less than six weeks.

Although lab diamonds are not naturally sourced, they are produced ethically as opposed to many of the natural diamonds on the market that are sometimes not ethically sourced. Both types of diamond utilize the same source, carbon, heat, pressure and time. However, one is formed in the lab and one is formed naturally over billions of years. They are indistinguishable to the naked eye however, they would be distinguishable under a microscope. 

To conclude, diamonds are made from carbon atoms that form as a result of heat, pressure and time. They are formed over billions of years and they come to the earth surfaces when volcanoes erupt or when the Earth’s plates move naturally. Lab diamonds essentially look exactly like naturally formed diamonds however, they are formed in a laboratory  instead of by the natural process of time, heat and pressure.
