Diamonds are among the rarest and hardest precious stones found on the earth. These naturally occurring gems are crystallized carbon atoms formed more than 3 billion years ago. They are formed under intense heat and pressure conditions about 100 miles below the surface of the earth.
Recently a rare mineral was discovered in a newly found ‘super-deep diamond’. This diamond was mined less than 0.62 miles underneath the earth’s crust and measured about 3 millimeters across.
Dr. Graham Pearson, a professor at the University of Alberta along with his research colleagues from the University of British Columbia and other establishments examined this diamond. Their findings state that the mineral inside the diamond is ‘calcium silicate perovskite’. Usually, this mineral is found around 400 miles below the earth’s surface.
According to Dr. Pearson, “The only possible way of preserving this mineral at the Earth’s surface is when it’s trapped in an unyielding container like a diamond.” He also mentioned that diamonds have a very distinct way of seeing what is inside the earth. “The discovery further highlights the fact that diamonds help preserve things which otherwise will never be seen” he added.
This super-deep diamond was found in South Africa’s Cullinan mines, famous as the source of the two largest diamonds in the British Crown Jewels. Dr. Pearson also said that the diamonds from this mine are highly valued commercially as well as scientifically since they provide insights into the earth’s core.
