Davemaoite - the theoretical mineral was found within a diamond from deep Earth

Scientists found for the first time mineral thought to exist only deep within our planet. It was hidden in diamond that was unearthed in Botswana. Scientists needed to use special x-ray lasers to identifi the material. It was named davemaoite after geologist Ho-kwang (Dave) Mao.

Davemaoite has the same chemical composition as another mineral wollastonite (CaSiO3), although both minerals differ in their atomic structure.
