陨石拍卖（陨石之家收藏）

Moldavit来自捷克共和国，颜色为浓绿。没有最近的碎裂痕。

Tektites（陨石玻璃）是天然玻璃，由一次巨大陨石撞击产生。 
陨石撞击地面时，陨石的动力能量在一场巨大的爆炸中释放出来，蒸发了陨石和周围的地表。岩石蒸汽从新形成的坑口喷出。蒸汽射流在更高的大气层中冷却并凝结成玻璃，雨落般散布，距离撞击点可达数百公里之远。
莫拉达维特是在1450万年前形成的，当时一颗巨型陨石撞击地球，发生在现今德国南部的区域，并在莫拉达维特周围形成了雷斯陨石坑（Ries Crater）。

Tektites are natural glass, generated by a huge meteorite impact. 
By hitting the ground the kinetic energy from the meteorite was set free in a huge explosion, that vaporised the meteorite and the surrounding earth surface. Jets of rock steam were ejected from the new born crater. The steam jets cooled down in the higher atmosphere and condensed to glass that rained down up to hundreds of kilometres away from the impact.
The Moldavites where created  14.5 million years ago when a big meteorite hit the earth at the place that is now southern Germany and created beside the Moldavites, the Ries Crater.
