Moldavite found in Chlum South Bohemia Czech Republic

Moldavite is an amorphous glassy green Tektite consisting of natural material. The hardness according to the Mohs hardness scale (1 to 10 in which diamond has a value of 10) is 6.5 to 6.9. It Moldaviet is approximately 15 million years ago by the impact of two meteorites of 1.5 km 150 meters in diameter respectively, which at the same time at an angle of 30-50 degrees with respect to the earth's surface insloegen at a speed of about 20 km / second. Almost certainly are respectively the Nördlinger Ries and Steinheimkrater in southern Germany craters hereof. Because of these impacts was an enormous amount of energy amounting to 1.8 million times that of the atomic bomb on Hiroshima. In addition, huge pressures were achieved at a temperature of more of 30,000 degrees Celsius. Thus, large quantities (approximately 150 cubic kilometers) of sand and earth and melted into space. After returning to the atmosphere have turned these fragments of earthly matter mixed with the extraterrestrial matter and fell back to the ground in a 'scatter area' which covers roughly the area of the Czech Republic. A very small part of it solidified into Moldaviet. Contrary to what most people claim, the Moldavite is found in several places in the Czech Republic. Smaller scatter areas independent of the Czech Republic, located in northern Austria and parts of Germany bordering the Czech Republic. The most precious Moldavite is found on the upper reaches of the Vltava River, in southern Bohemia. It has a green color with small inclusions. This stone is also called the Emerald Czech and has been incorporated into the crown jewels of the Czech Republic. The stones found in Moravia are brown in color and less costly. Because the sites of Moldaviet depleted rapidly, this stone is more expensive.
