- rare mineral found within a diamond
- Scientists were also surprised by the discovery.
Scientists have come to know of a new mineral found in the mine in the African country of Botswana, which has never been seen before. This mineral came out of the interior of a diamond. It is said that this mineral may be more valuable than gold and silver or diamond.
According to the report, the diamond was originally found decades ago at the Orapa mine in Botswana. Which was recently investigated by mineralogist Oliver Tschauner. The findings of their research were published this week in the journal Science. The diamond is four millimeters wide and weighs only 81 mg.
This diamond was sold by a diamond dealer to a scientist in 1987. However, no one knew its specialty at the time. At present, this diamond is preserved in the Museum of Natural History located in Los Angeles County, California, which was investigated by a scientist at the University of Nevada in Las Vegas.

This mineral, which came out of the interior of the diamond, has been named Davemaoite in honor of the famous geophysicist Ho-Kwang (Dave) Mao. This mineral is the first example of high pressure calcium silicate perovskite (CaSiO3) found on Earth. Scientists investigating it are also surprised, because a crystal-like mineral has been found inside the diamond. The diamond was 660 km below the Earth’s surface.
For the first time, such a mineral came out of the diamond.
Another form of CaSiO3, known as wollastonite, is commonly found throughout the world. But davemaoite has a crystalline structure that forms only in the high-pressure, high-temperature part of the Earth’s mantle. It is expected to be found in abundance in the Earth’s mantle. It is a mineral of geochemical importance.
However, scientists have never found any direct evidence of its existence because (davomite) breaks down into other minerals when pressure is reduced due to being brought to the surface for inspection.
But according to Live Science, the diamond that scientists recently found, which formed in the mantle about 660 kilometers below the Earth’s surface. Analysis of this diamond revealed that the unknown mineral buried within the diamond is just a davomite sample. The International Union of Minerals has now confirmed it as a new mineral.
Mineralogist Oliver Tschauner at the University of Nevada, Las Vegas, told Live Science that the davomite discovery was a “surprise.” According to Tschauner, the specimen they found was only a few micrometers in size.
