A diamond born in minutes: scientists create them in a laboratory using sliding pressure

The diamond was created in the laboratory in minutes

For the first time, the scientists were able to create diamonds in the laboratory at room temperature in minutes. To do that, they apply a sliding pressure force. Natural diamonds were formed in the depths of the Earth for over three billion years, and all the more amazing is the way they are artificially created. The specialists needed a diamond anvil set at room temperature. It is a high pressure equipment that compresses small samples of parts to extreme pressures.

The experiment also used crystallized carbon under a sliding pressure force, that is scientifically called a shear. The two diamonds formed together in stripes. Each of them had a core and shell structure after a pressure treatment.


The scientists compared it to the weight of 640 African elephants held onto the tip of a ballet shoe. The experts from the Australian National University took part in the experiment. It was carried out in a special laboratory using strong heat.

The new discovery showed that conventional diamonds can be created at the most common temperatures using a high pressure factor. According to a physicist Jody Bradby, the quality of diamonds depends on how the pressure level is applied as a sliding force.

The scientists believe that it allows carbon atoms to move into place, thereby forming a regular diamond that can be used for wedding rings. And it only takes a few minutes.
