Small meteorites are slowed by our atmosphere and, when they land, often make shallow indentations in the ground known as impact pits. Larger meteorites may form craters, while the most massive space rocks produce gigantic impact features called astroblemes, or “star wounds.” The biggest astroblemes on Earth are millions of years old and more than one hundred miles across, making them greater in area than some countries. Those meteorite impacts generated atomic bomb-sized levels of heat and pressure that melted Earth rocks into unique materials known as impactites. The meteorites that made those giant craters have long since weathered away, but the ghostly footprints of their cataclysmic collisions with Earth remain with us to this day —as impactites.
Genuine Moldavites are luminous green glasses formed 14.5 million years ago by the impact of a giant meteorite that created the 15-mile wide Reis Crater in Germany. The Moldavites were blasted some 200 to 400 kilometers, all the way to the modern-day Czech Republic! Mining has depleted the supply of this exquisite glass. While most impact specialists believe real Moldavites were created from melted terrestrial matter, they do display some characteristics associated with meteorites. Moldavites have a hardness rating of 5.5 and are often faceted for use in jewelry. When cut and polished, their deep green color is reminiscent of emeralds and peridot.
*Your Moldavite will be ~1 gram. Please be cautious when using the salt if you choose not to remove the Moldavite before use. It is sharp.
