Hematite Kidney Ore Crystal - Natural USA Mineral - Genuine Metallic Iron Ore - Certificate Included
£ 7.80
This listing is for an authentic Hematite Kidney Ore Crystal sourced from the
USA. You will receive the exact specimen shown in the photos, measuring approximately 40–60mm and displayed with a 1cm scale cube for size referenceThis crystal was carefully chosen for its rich metallic luster and distinct botryoidal (kidney-like) morphology—a hallmark of the kidney ore variety of hematite. Known for its dense weight and shimmering surface, this piece makes a fantastic addition to any mineral collection, metaphysical toolkit, or geological display.All of our Crystals are 100% Genuine Specimens & come with a Certificate of Authenticity. Key Features:
• Species: Hematite (Kidney Ore variety)
• Chemical Formula: Fe2O3 (Iron(III) Oxide)
• Crystal System: Trigonal
• Morphology: Botryoidal (kidney-shaped masses)
• Hardness: 5.5–6.5 Mohs
• Lustre: Bright Metallic
• Colour: Silver to steel-grey
• Streak: Reddish brown (classic diagnostic feature)
• Cleavage: None | Fracture: Subconchoidal to uneven
• Magnetism: Non-magnetic, but high iron content Geological Context:
• Depositional Environment: Forms in oxidized iron-rich zones of ore bodies, frequently as secondary mineralisation in sedimentary and hydrothermal environments
• Geological Stage: Can occur across a wide range of stages, including Precambrian banded iron formations (BIFs)
• Notable: Kidney ore hematite was historically significant as a major iron ore used in early metallurgy Other Taxonomic & Identification Info:
• Order: Oxide Minerals (Class: Simple Oxides)
• Family/Super Family: Not typically applied to mineral taxonomy
• Zone, Biozone: Not applicable to minerals
• Formally Identified By: First described and named by Jean-Baptiste Boussingault in the early 19th century; name derives from the Greek haima, meaning "blood," due to its red streak Whether you're a mineral collector, geologist, crystal enthusiast, or gift-giver, this metallic Hematite Kidney Ore is an extraordinary and authentic specimen ready to display or work with.You will receive the exact piece shown in the photos.
