Diamonds are one of the most highly sought crystals in the world, with the industry earning $79 billion in 2019 alone. In 2018, scientists were searching for diamonds– but not for money. They were more interested in the mineral inside of the diamond. Nobody had ever seen this mineral before, and its discovery changed science.

In 2018, scientists from the University of Alberta uncovered a never-before-seen mineral. That is not because the mineral is rare; it is actually the fourth most common mineral on Earth.
The mineral– called calcium silicate perovskite (CaSiO3) or perovskite for short– is so deep below the Earth’s surface that scientists had never seen it in person before.
