Kossel crystal

A Kossel crystal is a type of natural crystal characterized by a complex, often symmetrical internal structure formed through specific atomic arrangements. Named after chemist Wilhelm Kossel, these crystals grow by the orderly addition of atoms or molecules, resulting in well-defined geometric shapes. They are important in mineralogy and materials science because their internal structure influences properties like strength and optical behavior. Essentially, Kossel crystals are naturally occurring solid structures with intricate internal patterns that reflect their internal atomic organization.
