Iridescent Goethite (Spain)

Iridescent Goethite also known as Turgite and Hydrohematite, is a rare variety of Goethite and Hematite that crystallizes in the form of masses, botryoidal, and stalactite. The colorful rainbow within Iridescent Goethite comes from the mixture of Hematite & Goethite on the surface, creating a thin layer that interferes with light. This mineral can only be found in a few deposits around the world such as in Russia, Spain, Germany, China, and the U.S.A.

This mineral specimen is from Spain, with well formed botryoidal structures and a predominant iridescence makes this a sought after example of this type of mineral
