Moldavite (Czech: Vltavín) is an olive-green or dull greenish vitreous substance possibly formed by a meteorite impact. It is one kind of tektite. It was named by A. Dufrnoy for the town of Moldauthein (Czech: Týn nad Vltavou) in Bohemia (the Czech Republic), where it occurs. It is sometimes cut and polished as an ornamental stone under the name of pseudo-chrysolite.
