"Perfect" Pyrite dodecahedron (pyritohedron)

3D ModelNoAI

Locality: Roșia Poieni, Romania

Size: 2 cm x 2 cm x 2 cm

Formula: FeS2

Description: 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.

The crystal 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.

This Pyrite shows the characteristic striations (class m-3). More info here: https://skfb.ly/6XqoY
