Deep below the surface of our world, far beyond our feeble reach, enigmatic processes grind and roil.
Every now and then, the Earth disgorges clues to their nature: tiny chthonic diamonds encasing skerricks of rare mineral. From these tiny fragments we can glean tidbits of information about our planet’s interior.
A diamond unearthed in a diamond mine in Botswana is just such a stone. It’s riddled with flaws containing traces of ringwoodite, ferropericlase, enstatite, and other minerals that suggest the diamond formed 660 kilometers (410 miles) below Earth’s surface.
