Pallasites

Modern meteoriticists use the term "pallasite" to describe a certain structural class of stony-iron meteorites that contains abundant silicate inclusions in a nickel-iron matrix. Usually, the silicates are large olivine crystals, often of gem quality. These peridots make the pallasites some of the most attractive meteorites known, and cut and polished pallasite slices are highly coveted among meteorite collectors. Sometimes pallasites and pallasitic peridots are used in jewelry, making them the only genuine cosmic gemstones on Earth.

Based on their origin and formation history, the pallasites are regarded as samples of core/mantle boundary material from differentiated asteroids, inferring that a close relationship exists to the iron meteorites. Upon etching, larger metal portions of polished slices display typical Widmanstätten figures. In addition to this, pallasites display chemical, elemental, and isotopic trends that link them to specific chemical groups of iron meteorites, linking their origin to a common parent body. Hence, they are classified into three distinct groups or grouplets, similar to the chemical groups of the iron meteorites: (1) the main group pallasites, (2) the Eagle Station grouplet, and (3) the pyroxene grouplet.
