Moldavite Stone | Interesting Facts and Photos

Moldavite Green Coloured Mineraloid

Moldavite is a curious glass-like material that's believed to have formed following a meteorite shower that fell in the Moldau Valley (now the Czech Republic) around 14.8 million years ago.  Sometimes incorrectly spelt as moldovite, this translucent dark green coloured stone is relatively rare and when unpolished has a particularly distinctive texture.

Moldavite stones come from the family of 'glassy objects' known as tektites.  These include irregular and at times intricately shaped nodules or 'blobs' of a glassy substance that often contains tiny bubbles.  It has no internal crystal structure hence cannot accurately be referred to as a mineral.  Moldavite and other materials which have no significant crystal structure some of which include shungite, opal and obsidian are instead correctly known as a mineraloids.

The chemistry of tektites is unique and somewhat unexplained.  Samples taken from host rocks at the impact site where moldavite formed believe it was created following an impact from a meteorite.  The event would have caused enough heat to melt the bedrock which following the impact would have been ejected up into the atmosphere and possibly much higher.  As it rapidly cooled and fell back to Earth the liquidised stone formed glass-like bodies known as tektites.  Substances that formed during different impact events have different names but moldavite is by far the best known of all tektites.  The pitting on the surface of the stone is the result of it being submerged beneath water for a long period of time.

Moldavite is prized for its clarity and unique colour and is mostly used as a gemstone.  It's generally agreed that it's either an extraterrestrial meteoric material of unknown origin or the resulting splash from a meteoric impact.  Some believe that moldavite may be a by-product of a volcano on the moon whilst other more dramatic theories suggest it may have been produced by the explosion of an Earth-like planet in the asteroid belt.

During the Stone Age moldavite was used as a tool and thousands of years later was also valued as a talisman.  Folklore suggests an association with the fabled 'Stone of the Holy Grail' which was said to be an emerald that fell from the sky out of the crown of an angel.  Exposure to material associated with it was believed to quicken one's spiritual evolution.

Today in crystal healing moldavite is considered to be extremely powerful for spiritual development and expansion of the consciousness.  It's used for the purpose of communication to stimulate the co-operation and transfer of energies between those of extraterrestrial origins and those who inhabit Earth.  Moldavite is considered to be an important stone for this phase of human evolution.

Moldavite grades 5 to 5½ on Mohs scale of mineral hardness despite it not really being a mineral at all.
