Physical properties

Formation & geological history

Formed at the core-mantle boundary of differentiated asteroids approximately 4.5 billion years ago. These are rare stony-iron meteorites that represent a mix of planetary core metal and mantle silicates.

Uses & applications

High-end scientific study, luxury jewelry (sliced for pendants), and investment-grade museum or private collecting.

Geological facts

Pallasites are among the rarest meteorites, accounting for less than 1% of all known meteorite falls. The olivine crystals in pallasites are essentially space-borne peridot gems.

Field identification & locations

Identify by the 'Widmanstätten' pattern in the etched metal and the distinctive suspended green/gold olivine crystals. Found globally in impact sites; famous sources include Brenham (USA), Esquel (Argentina), and Fukang (China).
