Pyrite from Otvovice with Five-Sided Crystal Faces
This pyrite specimen comes from Otvovice in Central Bohemia, Czech Republic. A prominent pyrite crystal with a brassy metallic luster stands out against the dark gray to brownish, fine-grained matrix.
Its most striking feature is the pyritohedral crystal habit, characterized by well-defined five-sided faces. The crystal surfaces reflect light differently, creating a contrast with the predominantly matte, dark surrounding material. A small area of the crystal shows minor surface damage.
Measuring 5.5 × 3 × 2.5 cm, this compact specimen illustrates the distinctive crystal development of pyrite from Otvovice.
