Physical properties

Hardness: 6.5-7 (olivine) / 4-5 (metal matrix); Color: Dark brown/black fusion crust with amber-yellow to green translucent crystals; Luster: Metallic matrix with vitreous crystals; Structure: Orthorhombic crystals in an isometric metal matrix; Specific Gravity: Approx 4.8 - 7.5.

Formation & geological history

Formed at the core-mantle boundary of differentiated asteroids approximately 4.5 billion years ago. They are ejected during cataclysmic collisions and travel through space before landing on Earth.

Uses & applications

Primarily for scientific research to understand early solar system formation, high-end gemstone jewelry (specifically Peridot from space), and as a highly prized item for mineral collectors and museums.

Geological facts

Pallasites are among the rarest meteorites, representing only about 1% of all known meteorite falls. The Fukang meteorite is one of the most famous and beautiful examples, appearing like a stained-glass window when sliced.

Field identification & locations

Identify by the presence of translucent yellow-green olivine crystals embedded in a magnetic, nickel-iron metal matrix. In the field, look for a dark, weathered exterior (fusion crust) and use a high-strength magnet. Common locations include dry areas like the Atacama Desert or the Great Plains (Brenham, Kansas).
