A deep green Moldavite from Southern Bohemia in Czechia, formerly the Czech Republic.

Moldavite is a tektite, a natural glass formed as a result of a meteor impact. It's violent genesis is apparent when its internal features are viewed under magnification, with gas bubbles suspended in the turbulent, roiled, flowing structure of the material.
