What Are Meteorites? | Stony-Iron | 4K Ultra HD

The rarest of the three main types of meteorites, the stony-irons are divided into two groups: the mesosiderites and pallasites. Mesosiderites are believed to have been formed by violent asteroidal collisions, millions of year ago in deep space. Pallasites are made of roughly 50% nickel-iron and 50% green olivine crystals. Olivine is also known as the gemstone peridot. When sliced, pallasites can be colorful and even translucent and have an extraordinary otherworldly beauty. Of the approximately 60,000 officially recognized meteorites only about 300 are pallasites, making them rarer than diamonds or even emeralds. When you hold a pallasite in your hand, you are literally holding gems from outer space!
