An ancient diamond found in Botswana contains a never-before-seen mineral that came from deep inside Earth. The mineral – named davemaoite – provides a unique window into deep-Earth chemistry.
Originally dug up in a mine in Orapa, Botswana, the diamond is about 4 millimetres wide and weighs 81 milligrams. A dealer sold it in 1987 to a scientist at the California Institute of Technology who was studying diamonds, but neither the dealer nor the scientist had any idea how special it was.
The diamond, which is now at the Natural History Museum of Los Angeles County in California, was more recently analysed by Oliver Tschauner at the University of Nevada, Las Vegas. He is searching the world for what are known as “super-deep diamonds” to see what they can tell us about the deep interior of Earth.
Most diamonds form 120 to 250 kilometres underground, but those of the super-deep variety are born in Earth’s lower mantle, which begins 660 kilometres below the surface.

A diamond mining firm in Botswana has unveiled a 1,098-carat stone, describing it as the third largest of its kind in the world.
"[It's] a rare and extraordinary stone," the AFP news agency quotes Debswana Managing Director Lynette Armstrong as saying.
The gem was found on 1 June but publicly presented at an event on Wednesday in the capital, Gaborone, that was attended by President Mokgweetsi Masisi.
It is the biggest stone of gem quality to be recovered in the history of Debswana, a joint venture between the government and global diamond giant De Beers.
The biggest diamond ever discovered in the world was the 3,106-carat Cullinan, found in South Africa in 1905.
The second largest was 1,109-carat Lesedi La Rona - a diamond the size of a tennis ball, discovered at Karowe, northeastern Botswana, in 2015.
Botswana is Africa's leading diamond producer.
