Moldavite is a tektite-a mysterious group of glassy objects, that is the product of a meteor collision with Earth nearly 15 million years ago (14.8 to be exact) which created the Reis impact crater. It is believed to have fallen from the sky only once, over what is now called the Moldau River Valley in Czechoslovakia
