Iridescent Goethite is a spectacular variety of iron oxide that stands out in mineral collecting for its stunning play of metallic colours. Unlike common goethite, this specimen displays a natural iridescence on its surface, creating a visual effect similar to a rainbow or oil on water, due to the diffraction of light within its layers of oxidation.
