7.3 grams MoldaviteMoldavite is a unique type of Tektite, which are a natural variety of glass formed by meteorite impact. The meteorite's super heated mass strikes the ground with such force that it can melt silicate material from the earth's surface. This material is then catapulted into the air where it cools and lands many miles away from the impact site in the form of a Tektite. Moldavite's green, semi translucent color makes it a unique curiosity among Tektites,
