Fantastic stone with a distinctive formation is tektite. When meteorites impact the earth, they form into tektite, a type of natural glass. The word "Tektite" is a derivative of the Greek word "Tektos," which means "molten," and refers to something born in a fiery environment. The power of the collision rapidly melts the nearby boulders, which sends them soaring into the air. As soon as it reaches the air, it rapidly cools, resolidifies, and returns to earth as a thin piece of natural glass. Tektite can come in a variety of colors, depending on where a meteorite impacts.
