Moldavite is a type of glass that is believed to have been formed 14.7 million years ago during the impact of a large meteorite in what is now Germany. When the meteorite hit, some of the energy of the impact caused the ground to melt into glass, and liquid glass droplets were thrown up into the atmosphere. These cooled as they fell to Earth, and the resulting material is what you can see in these samples. Moldavite is a type of impactite: a material formed from the energy of an impact.
