Shiny black goethite, botroidal, France! Rare provenance Crystals on matrix - Height: 133 mm - Width: 80 mm- 983 g

Goethite is an iron oxyhydroxide mineral commonly found in weathered iron ore deposits, known for its deep brown to black colors and metallic to dull luster. Botryoidal goethite forms smooth, rounded, grape-like masses, adding an aesthetic quality beyond typical crystalline forms. The shiny black goethite specimen originates from France, a country with varied geologic settings yielding unique mineral specimens. This botroidal habit combined with a glossy appearance is unusual and visually striking, making it a sought-after collector's piece. Goethite's formation often results from the oxidation and hydration of iron-bearing minerals, prominently influencing soil and sediment colors. Besides its scientific and decorative appeal, goethite plays a role as an iron ore. Its provenance from France adds a layer of rarity, enriching its appeal to those interested in European mineral localities and distinctive mineral morphologies.
