17.20 CARAT AAA RICH GREEN CZECH MOLDAVITE

Moldavite is a green translucent silica meteoric glass created by a large cosmic velocity meteorite which vaporized when it struck the earth in Nordlingen, Germany, creating the Reis Crater.  A small percentage of that vapor was propelled into the ionosphere by the impact explosion through the hole punched in the earth's dense atmosphere.  When this silica vapor reached the cold of outer space, it condensed then solidified and fell back to earth creating a strewn field of lime green tektite, several hundred miles away in the Moldau River Valley north of Prague, Czechoslovakia.  Thus the name Moldavite. There are several location names for different areas of the valley where Moldavite is dug from the ground.   Moldavite is one of the rarest varieties of tektite.
