What is pallasite?

Pallasites are a type of stony-iron meteorite that is composed of olivine crystals embedded in a matrix of nickel-iron alloy. They are some of the rarest and most desirable meteorites for collectors due to their unique composition and aesthetic appeal.

Pallasites are thought to originate from the boundary between the mantle and core of a differentiated asteroid that was disrupted by a collision, exposing the olivine-rich mantle material to the nickel-iron core material. This rare combination of materials gives pallasites their distinctive appearance, with translucent green olivine crystals set against a shiny metallic background.

Pallasites can vary in size from small fragments to large masses weighing several tons. They are often prized for their beautiful gem-quality olivine crystals, known as peridot, which can range in color from yellow-green to olive-green.

Pallasites have been found in various locations around the world, with some of the most famous examples coming from Argentina, Russia, and Antarctica. These meteorites are highly sought after by collectors and researchers alike, due to their scientific value in studying the early solar system and their stunning beauty.
