Moldavite (Czech: vltavín) is a forest green, olive green or blue greenish vitreous silica projectile glass formed by a meteorite impact in southern Germany (Nördlinger Ries Crater)[3] that occurred about 15 million years ago.[4] It is a type of tektite and a gemstone.[5] Material ejected from the impact crater includes moldavite, which was strewn across parts of Germany, the Czech Republic and Austria.[6]
