NFG72XXX: Group of Goethite crystals with intense and striking iridescence, showing a wide range of metallic colours including golden, green, violet and bluish reflections.
The main interest of the specimen lies in its provenance. It was found by Fermín Clemente at the Poderosa Mine, a classic locality mainly known for its Azurites. We are not aware of previous references to Goethites with this type of iridescent coloration from this mine, which adds further interest to the specimen.

Geologically, the Goethite formed as an alteration product of iron-bearing minerals present in the deposit, developing in this case surface coatings responsible for the striking iridescence observed.
