Botryoidal Goethite (Iron Hydroxide) Specimen on Black Background. A detailed macro photograph of a raw Goethite specimen, dramatically isolated against a solid black background. The specimen displays a classic botryoidal (grape-like) and reniform (kidney-like) habit, with a convoluted, bumpy surface. The color is predominantly a dark, brownish-black with a dull to sub-metallic luster. Patches of vibrant, earthy orange and reddish-brown rust are scattered across the surface, highlighting the texture and indicating the mineral's iron content and oxidation.Photographed at the Chongqing Natural Resources Science Popularization Museum, this is a prime example of Goethite, an iron oxyhydroxide. It is a very common mineral, typically formed as a secondary product from the weathering of other iron-bearing minerals. For millennia, earthy forms of goethite have been a crucial resource as a pigment (ochre). It is also a significant iron ore. In metaphysical beliefs, Goethite is considered a powerful grounding stone that connects one to the Earth and aids in processing deep-seated emotions. This image is ideal for geological studies, educational content, or as an abstract natural texture background.
