iron meteorite

Iron meteorites are metallic remnants of ancient planetary cores, primarily composed of iron and nickel, and are renowned for displaying the Widmanstätten pattern—a distinctive intergrowth of kamacite and taenite crystals formed through ultra-slow cooling over millions of years. This intricate, geometric structure becomes visible when the meteorite is sliced, polished, and acid-etched, revealing a natural lattice that is both scientifically valuable and visually striking. Among the most sought-after iron meteorites by collectors and researchers are specimens from the Gibeon (Namibia), Muonionalusta (Sweden), Sikhote-Alin (Russia), Canyon Diablo (USA), and Campo del Cielo (Argentina) falls. These meteorites not only showcase exceptional Widmanstätten patterns but also hold historical and geological significance, representing fragments of early planetary formation in our solar system.

Stony-iron meteorites

Stony-iron meteorites are among the rarest and most visually striking types of meteorites, composed of roughly equal parts metallic iron-nickel and silicate minerals, primarily olivine crystals. These meteorites are thought to originate from the boundary layer between the metal core and silicate mantle of differentiated asteroids, offering a unique glimpse into planetary formation. The crystals—often transparent to translucent and amber to green in color—are especially prominent in pallasites, the most well-known type of stony-iron meteorite. When cut and polished, the embedded olivine (peridot) crystals appear suspended in a metallic matrix, creating a mesmerizing, gem-like effect. Some of the most sought-after stony-iron meteorites include the Esquel (Argentina), Imilac (Chile), Seymchan (Russia), and Fukang (China) specimens, prized by collectors for their beauty, rarity, and scientific significance.
