Pyrite Crosses

These are famous "iron cross" pyritohedron twins where the exterior of a pyrite crystal transforms into an iron-related mineral like hematite or goethite.
Sourced from the Gachalá and Guavio-Guateque District which is located in the Cundinamarca Department of Colombia, the region is renowned for sharp, architectural iron-cross twin crystals.
While the color may occasionally be the brassy gold associated with pyrite, it is more often reddish-brown characteristic of hematite.
