Moldavite also known as the 'Bouteille Stone' or as 'Vltavin' in Czech, is an olive-green to dull brown-green vitreous gemstone. The unusual green gem garnered much fame and attention owing to its unusual origin. Moldavite was thought to have been formed by condensed rock vapors after a meteorite impact. Moldavite belongs to the Tektite group of minerals, which is a small family of natural glass rocks. Moldavite is sometimes touted as 'the only known extraterrestrial gemstone on Earth', or as 'the gemstone born from the stars'.
GIA have now classed this gemstone as a new gemstone category.
