£ 8.40
GENUINE GOETHITE CRYSTAL SPECIMEN FROM MOROCCOThis listing is for a genuine Goethite crystal specimen from Morocco, carefully
chosen for its natural mineral character, earthy colouration, and distinctive geological appearance. The photo shows the actual specimen you will receive, making this a suitable piece for mineral collectors, crystal displays, natural history collections, geology education, cabinet presentation, desk décor, or as a thoughtful gift for someone who appreciates genuine rocks, crystals, and minerals.Full sizing details can be seen in the photo. This crystal is supplied with a generic Certificate of Authenticity lifetime guarantee card, confirming it as a genuine specimen. MINERAL SPECIES AND CRYSTAL TYPEGoethite is an iron oxyhydroxide mineral with the chemical formula FeO(OH). It is one of the most common and important iron-bearing minerals and is a major component of many iron ore deposits, weathered rocks, lateritic soils, and oxidation zones. Goethite is named after the German writer and scientist Johann Wolfgang von Goethe, who had a strong interest in mineralogy.Goethite belongs to the orthorhombic crystal system, although well-formed individual crystals are less common than compact, botryoidal, stalactitic, fibrous, massive, earthy, or radiating forms. Many specimens show rounded, lumpy, layered, or velvety textures, created as iron-rich minerals alter and recrystallise under surface or near-surface geological conditions. This makes Goethite particularly appealing for collectors who enjoy natural iron minerals with strong texture and geological presence. COLOUR, TEXTURE AND NATURAL APPEARANCEMoroccan Goethite specimens often display rich earthy tones, including dark brown, reddish brown, golden brown, rusty orange-brown, blackish brown, steel-grey, or nearly black areas. The surface lustre can vary from dull and earthy to silky, submetallic, or bright on more crystalline faces. Some pieces may show botryoidal rounded surfaces, fine sparkling crystal areas, fibrous growth, natural cavities, iron-rich crusts, or layered mineral textures.The colours are linked to the mineral’s iron content and formation history. Natural colour variation, surface irregularities, small fractures, contact marks, and matrix areas are typical of rough Goethite specimens and should be appreciated as part of the specimen’s genuine geological character. The contrast between darker iron-rich areas and warmer brown or ochre tones can make Goethite an attractive and unusual display mineral. GEOLOGICAL FORMATION AND MOROCCAN ORIGINGoethite commonly forms through the weathering and alteration of iron-bearing minerals such as pyrite, siderite, magnetite, hematite, and other iron-rich minerals. It is especially common in oxidation zones, where water and oxygen interact with iron minerals near the Earth’s surface. Over time, these reactions can produce iron oxyhydroxides, including Goethite, limonite mixtures, and related iron-rich deposits.In geological settings, Goethite may form as vein fillings, crusts, nodules, replacement material, or coatings in cavities and fractures. It is also a major mineral in some ironstone and lateritic deposits. Morocco is well known for producing a wide variety of collectable minerals, including iron oxides and associated minerals from arid and mineral-rich geological environments. Moroccan Goethite is valued for its natural textures, strong earthy colours, and suitability as a display specimen. COLLECTING, DISPLAY AND CAREThis Goethite specimen is ideal for display in a mineral cabinet, on a shelf, desk, specimen tray, geology collection, natural history display, or educational rock and mineral set. Its iron-rich composition, distinctive surface texture, and natural Moroccan origin make it an interesting piece for collectors of oxide minerals, ore minerals, and unusual geological formations.Goethite has a Mohs hardness of approximately 5 to 5.5, though matrix areas or earthy sections may be softer or more fragile. Handle the specimen with care, especially if it has delicate crystal surfaces, fine botryoidal texture, or friable edges. Avoid soaking, harsh chemicals, abrasive cleaning, and prolonged damp conditions. To preserve the natural surface, gently dust with a soft dry brush or wipe lightly with a soft dry cloth.
