Moldavite is the result of a huge Meteor striking the Earth about 15 million years ago. In the instant before impact part of the Earth's crust melted and was flung high into the atmosphere to land far away in the Moldau valley. In that instant of "boiling off" some particles of the original Meteorite mixed with the Terrestrial, so Moldavite although mostly Earthly does contain some traces of the ExtraTerrestrial Meteor. While writing this, Rosetta has just landed on a Comet and the pics of it's surface look so similar to the patterns in Moldavite that I can't help feeling that it somehow carries the soul of the Comet that Fathered it on Mother Earth.
Moldavite is the only naturally occurring transparent green Obsidian. it's only found in one location so it's value increases every year. writing this, Guess that means Moldavite jewellery carries literally a massive punch :-) which will transform and revitalise your Heart, reconnecting it to the Universe & bringing about a powerful positive personal transformation.
