Pyrite crystal (pyritohedron), Roşia Poieni, RO

3D ModelNoAI

Locality: Roşia Poieni, Romania

FOV: ~8 mm

Formula: FeS2

Description: This is my first contact with macro photogrammetry. There is a lot of space for improvements. The main crystal is ~ 4 mm long and represents a dodecahedron, also known as Pyritohedron. The pyritohedron is an isometric closed crystal form of 12 faces, each an irregular pentagon. It is named after pyrite, which characteristically has this crystal form. Pyrite’s brassy golden color led to it being called “Fool’s gold”, but the name of the pyrite comes from the Greek word pyr meaning “fire” because sparks flew from it when struck with another mineral or metal.
