MOLDAVITE
|
|
Moldavite is a type of TEKTITE, a natural glass rock with rounded or irregular shapes and pitted or wrinkled surfaces. The Impact Theory states that TEKTITES may be fused glass that formed during an impact of a meteor with layers of rock on the Earth's surface. The TEKTITE contains properties from both the meteor and the Earth crust at the impact site.
MOLDAVITE is a jewelry-quality Tektite, stemming from a meteorite that collided with earth approximately 14.7 million years ago and created the Ries crater in Germany. Moldavites are found in a "strewnfield" centered around Moldavia in former Czechoslovakia.
