The Mineral is called calcium silicate perovskite. It's hypothesized to be one of the most abundant ingredients deep inside the Earth's mantle due to the heat and pressure down there. But at depths shallower than 700 km, it becomes unstable so that it can't exist at the Earth's surface. So while it had been hypothesized to exist down inside the Earth in great quantities and to actually be one of the more abundant ingredients of planet Earth, it's always been theoretical and has never actually been seen... until now.
It was found in a diamond from South Africa that seemed to have something inside it. The diamond is believed to be a 'deep' diamond that formed way down inside the Earth and various kinds of spectrographic analysis revealed the inclusion to be the missing calcium silicate perovskite. Since this material can't survive in surface conditions, it needs to be encased in a hard protective shell that will keep it under sufficient pressure. What better protective shell can a mineral have than a diamond casing? The diamond presumably formed in the kind of hot, high-pressure mantle regime where the perovskites thrive.
It isn't just true of girls. Diamonds are a mineral's best friend too (at least if the mineral is perovskite).
Which just goes to show that there might be a lot of exotic geochemistry going on down there in conditions that we don't see up here.
