14 million years ago, a meteor traveling through the blackness of space, made contact with Earth. In an instant, its force created a 16-mile-wide crater. The heat and intensity of impact forged a unique type of stone suffused with microscopic diamonds. Lost to time but hiding in plain view beneath checkered farmlands and red-roofed villages in the Bavarian countryside, the Nördlinger Ries crater is a cosmic fingerprint, a single touch reverberating through time, a kaleidoscopic echo continuing to transform all around it.
