Cohenite; Kopeysk, Urals, Russia; MM; unique piece
Cohenite from Copeysk, Urals, Russia. Micromount as unique piece for mineral collectors.
Cohenite is a rare iron carbide mineral best known from meteorites but also found in terrestrial environments. This specimen originates from Kopeysk in the Ural Mountains of Russia—a classic mineralogical region renowned for producing numerous rare and scientifically significant species. The piece is mounted as a micromount in a clear capsule, making it ideal for systematic collections and mineral specialists.
Composed of iron, nickel, and carbon, Cohenite crystallizes in the orthorhombic system. It typically forms under highly reducing, iron-rich conditions, either deep within the Earth's crust or inside iron meteorites. This makes it an intriguing mineral that bridges the worlds of terrestrial and extraterrestrial geology.
Collectors focusing on metallic minerals, carbides, or minerals from the Urals will find this specimen especially appealing. The crystals display a metallic luster and are partially well-developed on a matrix, offering a visually compelling and scientifically valuable addition to any advanced collection.
An excellent piece for teaching collections, mineral enthusiasts, and specialists in rare metallic phases—a remarkable example of geological diversity formed under extreme conditions.
